抽象的

The growing importance of public innovation has been manifested through the creation of
policy labs: spaces for policy experimentation and innovation that work for or within a
government entity. The rise of this phenomenon in Europe was evidenced by the creation of
a policy lab by the European Commission (EC) 在 2016 and the publication by the EC of a
report identifying policy labs and their influencers in Europe. Public innovation is increasingly
based on national and international networks, giving rise to complex ecosystems involving
participation by multiple actors from countries with different administrative approaches. 我们的
study uses social network analysis of these labs’ Twitter profile data to map the European
Union’s (欧洲联盟) public innovation ecosystem and identify the major influencers. Policy labs and
their influencers are analyzed by administration style by using a large geographical database.
The results reveal a complex global network of influencers and a strong predominance of
the Anglo-Saxon administration style. From an EU perspective, our systematic analysis of
influence is particularly important in the post-Brexit context, helping to foster a genuine public
innovation ecosystem that is both autonomous and interconnected with the aim of facing
challenges such as the Sustainable Development Agenda and COVID-19 crisis recovery.

介绍

Public sector innovation has become one of the most promising topics in public governance in
recent decades (摩尔, 2005) and this has led to its being institutionalized (Hjelmar, 2019). 这
speed with which social and technological changes occur, the complexity of social problems
and a globalized world—thanks to trade, 社交网络, and information flows—have pushed
governments to adopt various solutions to promote public innovation (经合组织, 2019) 和, 因此,
address common challenges more creatively, more effectively, and with greater social legiti-
macy. As Hartley (2005) pointed out, public innovation is a process of change that produces
durable and significant transformation in how an organization operates. This happens not just
by creating original ideas but also as the result of applying existing ideas to new institutional
上下文 (Gieske, George et al., 2020; 摩尔, 2005). Efforts to advance public innovation have
been made at various levels of government administration, from local to supranational levels.

Innovation labs, innovation networks, innovation schemes, and prizes are some examples of
the institutionalization of public innovation (经合组织, 2017). In the present article, we focus on
innovation labs or policy labs in Europe, whose mission it is to use innovative and participatory

methodologies in designing public policies (Hjelmar, 2019; Lewis, McGann & Blomkamp, 2020;
Romero-Frías & Arroyo-Machado, 2018; Tõnurist, Kattel, & Lember, 2017). Labs are attempts to
institutionalize and promote the transformation of public organizations from the inside out, 在
order to respond to citizens’ demands for openness and participation. 同时, they seek
to activate an approach in which smart citizens and employees foster collective intelligence.
Policy labs place citizens at the center of their innovation processes in open, experimental ways
to promote more proactive institutions that seek to recover the political initiative and increase
people’s confidence in them. Concepts such as coproduction, citizen participation in innovation
流程, 实验, and managing through networks all fit within the New Public
Governance paradigm (Pollitt & Bouckaert, 2011; Torfing, Andersen et al., 2020). This new
theoretical approach takes into account sociology and network theory and acknowledges
the increasing uncertainty affecting public management in the 21st century (Osborne,
2010), a political scenario that policy labs are seeking to address in the public sector.

Policy labs are generally identified by a range of names: government labs or govlabs, 民众
sector innovation (PSI) labs (McGann, Blomkamp, & Lewis, 2018), innovation labs (Tõnurist
等人。, 2017), or policy labs (Fuller & Lochard, 2016), 除其他外. Throughout this study, 我们
will use the term policy lab (or simply, labs), as this was used by the European Commission
(EC) when creating its own lab in 2016.

To understand the global outreach of policy labs in Europe and around the world, 这是
necessary to adopt various means of classifying public administration according to their
特征. As stated, policy labs meet governments’ needs to reorganize their innovation
流程, taking into account two main ideas: technological change and user- and citizen-
centric governance and management. Based on an analysis of the literature, Voorberg,
Bekkers, and Tummers (2011) identified the following drivers of the innovation environment:
the social and political complexity of the public organization environment; the characteristics
and degree of the legal culture in a country; the type of governance and state tradition in the
国家; and the allocation of resources, resource dependency, and the quality of relationships
within the networks among the stakeholders involved. Both the legal culture and the type of
governance and state tradition seem to be relevant drivers to understand the nature of policy
labs. 例如, innovation in the public sector is dependent on the capacity to embark on a
process of “trial and error,” experimentation, collaboration, and availability of resources.
Dwivedi (2005, p. 20) refers to administrative culture as “the modal pattern of values, 信仰,
attitudes, and predispositions that characterize and identify any given administrative system.”
This idea, also referred to as Administration Style, is used in this study to classify labs according
to their different national traditions. Administration Style has been used to explain the evolu-
tion of public sector reforms (Bonsón & Bednárová, 2018), including aspects such as transpar-
ency, accountability, and e-participation (Pina, Torres, & Royo, 2007; Royo, Yetano, &
Acerete, 2014). According to these authors, the dissemination of public sector management
innovations is influenced by their organizational and administrative culture, historical back-
地面, and legal structure. 所以, this can be a useful theoretical approach to understand
the creation and popularization of policy labs and their influencers across countries.

In EU countries, four broad styles of public management may be distinguished, as follows

(Torres, 2004):

(西德:129) Anglo-Saxon (AS, including Ireland and the United Kingdom): emphasis on efficiency, effec-
主动性, and value for money in public administration; more likely to introduce market
mechanisms, notions of competitiveness, and attempts to make public services more respon-
sive to their users or customers; adaption of private sector experience to the public sector.

Who influences policy labs in the European Union?

(西德:129) Germanic (GE, including Austria and Germany): Weberian approach, involving a com-
plex federal system; administrative practice marked by an overriding legalistic philoso-
phy within the constitutional framework; strong hierarchy with detailed regulations.
(西德:129) Nordic (NO, including Denmark, 荷兰人, 芬兰, 瑞典, 和挪威): A
mixture of the AS and Germanic types; public administration model that seeks efficiency
and effectiveness through the satisfaction of citizens’ needs; strong tradition of negotia-
tion and consultation.

(西德:129) Southern EU countries (SO, including Belgium, 法国, 希腊, 意大利, 卢森堡,
Portugal, and Spain): influenced by the French legal model focused on administrative
法律; definition by central government of overarching state rules for field services and a
unitary treasury system.

This classification focuses mainly on Western Europe, which may a priori present limita-
tions due to the enlargement of the EU with countries that have postsocialist administration
traditions (Painter & Peters, 2010). 然而, the EU report upon which this research is based
does not identify policy labs from these countries and therefore its scope fits the aforemen-
tioned classification (IE。, mainly focused on Western European tradition).

Public innovation practice in Europe and around the world is made up of globalizing instru-
评论, such as conferences and networks, giving rise to a complex and interconnected public
innovation ecosystem. Policy labs are one of the most novel and relevant entities in this eco-
系统. Due to their institutional nature and goals, most of them have active profiles on social
媒体, where they communicate and build networks with other actors.

Our main objective is to explore this global ecosystem by analyzing structural relations on
the Twitter profiles of European labs to obtain a better understanding of public innovation
communities and the extent to which they are connected to the different public administration
styles. This can provide insights on how different management and innovation cultures relate
to each other in a field that, unlike competitive political processes such as electoral cam-
paigns, is built on cooperative dynamics (Sørensen & Torfing, 2011). 此外, Dawes
and Gharawi (2018) pointed out the lack of empirical research into Transnational Public Sec-
tor Knowledge Networks, in which governments engage to share knowledge and information.
This study helps to fill this research gap in relation to policy labs, which are an example of this
type of network, as well as verifying the effectiveness of new media as a means of unveiling
new actors and potential partners.

Based on this general goal, our research questions are the following:

RQ1: What kind of network exists between European policy labs and their potential influ-

encers (their followed profiles or friends)?

RQ2: What is the profile of European policy lab influencers on Twitter? Does social network
分析 (SNA) validate the identification by experts of influencers in the EC-
commissioned report?

RQ3: How are policy lab influencers distributed geographically and according to their

public administration style?

2. POLICY LABS IN EUROPE
在 2016 the EC founded its own policy lab1, defined as a “a space designed to foster creativity
and engagement, and to develop interactions, processes and tools able to bring innovation

Who influences policy labs in the European Union?

into European policy-making”2. It was conceived of as both a physical and conceptual space
where solutions are delivered through testing, experimenting, codesigning and visual thinking,
using participatory methods that integrate all the stakeholders’ views. 在六月 2016, the EC
Joint Research Centre, on which the lab depends, commissioned and published a report enti-
tled “Public Policy Labs in European Union Member States.” This was prepared by Conseil &
Recherche and the 27e Région (Fuller & Lochard, 2016) and their main goal was to map the
policy labs operating in the EU at that time—64 laboratories in 13 countries—and their
principal topics of interest. 据我们所知, this report has not yet been replaced
or updated.

迄今为止, research into policy labs in Europe has been scant, although recently there has been
a growing number of studies on policy design and labs (Olejniczak, Borkowska-Waszak et al.,
2020; van Buuren, 刘易斯等人。, 2020). To our knowledge, some studies have analyzed Euro-
pean labs in a wider context. 例如, Olejniczak, Newcomer, and Borkowska-Waszak
(2016) 分析过的 20 labs around the world, including Europe, through a literature review and
analysis of policy evaluation practices, to determine their value and impact. Tõnurist et al.
(2017) 分析过的 35 public innovation laboratories around the world to determine their main
characteristics and the reasons for their creation. Their methodology focused on empirical
analysis by triangulating data from in-depth interviews, document analysis and a survey of
i-labs. McGann et al. (2018) tried to understand the role of public sector innovation labs in
policy systems by analyzing publicly available information of a sample of 20 labs worldwide.
Focusing solely on the European context, Romero-Frías and Arroyo-Machado (2018) used net-
work analysis to reveal the structure of relationships between the 42 的 64 labs in the EC
report that have a presence on Twitter, conducting a content analysis of the labs’ Twitter pub-
lications to identify their topics of interest. 最近, Olejniczak et al. (2020) analyzed the
功能, 结构, and processes of 20 policy labs from all around the world, 包括
欧洲.

The EC report mapped the main European policy labs and offered a selection made by the
report’s authors of the so-called “influencers” of these policy labs. 桌子 1 shows a list of 13
influencers that are defined as “entities that both advocate and propel the creation of Policy
Labs, but are not in and of themselves attached to a specific government organization.” Influ-
encers play a role in advocating the creation of policy labs and providing experience,
资源, and networking, as well as functioning as central nodes in the policy lab manager
网络.

3. SOCIAL NETWORK ANALYSIS AND INFLUENCER IDENTIFICATION

Social network analysis is based on network theory, which enables us to understand and
model complex systems (Lewis, 2008). Different types of graph reflect real-world behavior
through individual participants (节点), and the implicit or explicit relationships between them
(边缘), whether or not directionality exists in the relationship. Given its popularity and
openness to data collection, Twitter is one such complex system in which we can observe
relationships through various indicators: number of friend/follower connections, retweets,
and mentions (Del-Fresno-García, 2014). These relations can be analyzed from two general
perspectives by focusing on social relations between individuals through established follow-up
连接 (taking account of the double, bidirectional follower/friend perspective) 和
information network based on tweet-produced interaction (迈尔斯, Sharma et al., 2014). 这
objective is to describe a given community’s underlying network and analyze the existing

clusters and a range of indicators and statistics. Influence is one of the issues that can be
researched through social network analysis.

Influencers have largely been analyzed in marketing studies, particularly in relation to
社交媒体 (Casaló, Flavián, & Ibáñez-Sánchez, 2017; Hsu, Chuan-Chuan Lin, & 蒋,
2013; Uzunoğlu & Kip, 2014; 张 & Caverlee, 2019), where digital influencers have a
wider reach among their online social contacts than in traditional offline communication
(Lyons & Henderson, 2005). This is how brands seek to design effective campaigns by using
influencers as a reference group to influence their audience. The identification of relevant
influencers has become a popular research topic in business (Kim & 特兰, 2013; 刘, Jiang
等人。, 2015; 朱, 2013). Numerous studies try to identify influencers on social media plat-
形式, given their increasing importance as a part of companies’ marketing strategies (Nip &
福, 2016; Sun, 王等人。, 2016).

Shmargad (2018) studied Twitter influencers in politics using retweets as the best indicator
of a given user’s influence, as they capture other users’ willingness to engage with others’ mes-
sages. Centrality has also been studied in the specific case of social media platforms, conclud-
ing that a relationship exists between an individual’s position in a group and their behavior
(克莱因, Ahlf, & 夏尔马, 2015). In politics, influence has mainly been studied in relation to
electoral competition (Shmargad & Sanchez, 2020), although generally these studies focus
on a particular event involving a surge in social media communication and not on the network
of relations between institutions (policy labs in our case), where the act of following another
profile can involve recognition in a process of accumulation of social capital (Bourdieu, 1986).

Our study explores the nature of the global public innovation ecosystem taking as its start-
ing point the influencers of European policy labs, defined in the EC report as entities that advo-
cate the creation of policy labs. This influence at an institutional level will be analyzed by
following the different relationships in a given policy lab’s Twitter network.

4.1. Sample and Research Design
Our initial sample consisted of 64 policy labs and 13 “influencers,” identified in the EC-
commissioned “Public Policy Labs in European Member States” report. This report has been
taken as a starting point to explore this public innovation ecosystem, given the relevance of the
EU and the importance of the expert reports they commission in terms of agenda-setting and as
foundations for future regulatory decisions.

We identified some problematic policy lab Twitter profiles that have associated Twitter
accounts that may not be exclusively dedicated to lab activity. Labs with descriptions suggest-
ing they are primarily or exclusively used by the policy lab were included. 相似地, 我们有
included labs with a wider scope if their profiles or tweet content refer to innovation activities
covered by the abovementioned definition (IE。, CityofOdense and AlpesMaritimes). 在一些
案例, we have found that accounts have been redirected (例如, UKTIIdeasLab is now redi-
rected to TradeDesignLab—we have included the latter in the present study). Another case
was the UNHCR policy lab, which links globally to the United Nations but was located in
the online Refugee Aid Initiative in Greece report (UNHCRInnovation).

Initial profile identification and data collection took place in spring 2018, finding that 42 的
这 64 labs had a presence on Twitter. A second survey was conducted in September 2019 到
determine any subsequent changes. 在这个, we found that MindLabDK, one of the most prom-
inent European policy labs according to Romero-Frías and Arroyo-Machado (2018), 有

disappeared following cessation of activities at the end of 2018. 此外, PFI Region
Sjælland (PFI_regsj) and Trade Design Lab (TradeDesignLab) 不再存在.

At that point, 这 39 policy labs included in the EC report (plus the EC’s own lab) 是
distributed geographically as follows (from highest to lowest number): 13 in the United
王国, eight in France, three each in Denmark, 西班牙, and the Netherlands, two each in
Italy and Sweden, 和 1 each in Finland, 希腊, 爱尔兰, and Portugal, plus the EU lab.

4.2. Data Processing

We collected information on Twitter related to the labs in the sample (42 在 2018 和 39 在
2019) and to the so-called “influencers”; this including followers, 朋友们, number of tweets,
description, 列表, profile set-up date, 地点, 和语言.

The data gathered (profiles and interconnections) were collected through scripts pro-
grammed in python using the Tweepy and Twython libraries. We also used R3 to treat some
数据. In our study we used the locations found in the free field offered to Twitter users. Having
collected the locations, we searched OpenStreetMap API to geolocalize the accounts. 最后,
we created heat maps using R to indicate the presence of accounts worldwide.

We analyzed the policy lab network by visualizing the connections between labs with the
Gephi3 tool (Bastian, Heymann, & Jacomy, 2009). The graph obtained shows how the sample
labs related to each other and which network nodes were the most relevant. We conducted
this analysis on a global scale, taking account of the network as a whole and paying attention
to each node or lab at local level. At a global level, we calculated the diameter, maximum
eccentricity (greatest distance) between all node pairs, and the mean distance between all of
他们. For each node the degree of entry (indegree) and exit (outdegree) have been taken into
帐户; these are equivalent to account followers and friends, 分别. 同样地, eigen-
vector centrality has been calculated (Bonacich, 1972). This is determined by using an itera-
tive process that takes account of the degree of entry and exit of a node and the quality of these
连接. We also calculated descriptive statistics for the mean and standard deviation (标清)
from follower and friend data.

总共, 41,058 朋友们 (outdegree) 和 843,701 followers (indegree) of policy labs have
been downloaded; of these, 36,338 朋友们 (potential policy lab influencers) 和 786,453
followers are unique. These figures indicate that policy labs attract much more attention from
third parties than they pay to others by following their accounts.

The profile geolocation process revealed that 510,715 Twitter accounts provided locations,
其中 110,156 were unique. Because this is not a standardized field on Twitter, the specific
country to which each account belonged had to be identified using the OpenStreetMap API.
一些 73,769 unique locations were correctly identified, giving 487,232 different Twitter
accounts associated with a specific country. 因此, 77.14% of initial friends and 58.38% 的

Who influences policy labs in the European Union?

(西德:129) Nordic (NO) (9): 丹麦 (3), 荷兰 (3), 瑞典 (2), and Finland (1)
(西德:129) Southern Europe (SO) (15): 法国 (8), 西班牙 (3), 意大利 (2), 希腊 (1), and Portugal (1)

There is no Germanic policy lab in the sample. All geolocalized Twitter accounts in Europe
were classified by administration style and then visualized through a Sankey diagram to ana-
lyze the location of influencers and the subsequent patterns of policy labs. We grouped policy
labs by administration style and influencers by country. To improve the visualization, 国家
representing less than 0.2% of total influencer connections were eliminated. We then estab-
lished the follow-up flows between administration styles and influencers using percentages of
influencers over the total instead of absolute values.

4.4. Content Analysis

We conducted a content analysis of Twitter profiles to classify the top policy lab influencers
identified in our analysis by influencer type and country of origin (Holsti, 1969). Our profile
sample is based on the top 100 influencers of all European policy labs and on the top 50 labs
in each of the three administration styles identified in the study sample. We ranked influencers
by indegree and eigenvector centrality.

An initial taxonomy was explained to two independent research assistants who were asked
to classify part of the sample to test the classification scheme. After sharing results, 一些
adjustments were agreed which led to the establishment of the following influencer types:
Academia; 商业; 专家 (female/male); Government institutions; 媒体; Networks and
国际组织; Nonprofit organizations; and Others (including conferences,
事件, and internet services). We also recorded country profiles. The three researchers then
coded the influencers separately and shared their results, reaching a consensus in the few
cases on which they initially disagreed.

最后, to respond to our research questions, we used a contingency table and correspon-

dence analysis to assess differences between administration styles and influencer type.

5.1. European Policy Lab and Influencer Network
To answer RQ1, “What kind of network exists between European policy labs and their poten-
tial influencers (their followed profiles or friends)?,” Figure 1 shows the network of policy labs
and influencers; 那是, all outdegree connections (朋友们). In some cases this relation is recip-
rocal. From the labs’ perspective, this is reflected by the directions and colors of the edges,
with blue for outdegree connections and red for indegree connections. Policy labs are repre-
sented by blue circles and influencers by red circles. The size of each node is calculated from
the indegree, except for those labs that have been shown as equivalent in size to indegree 7 到
give a homogeneous representation that allows the reader to focus on the influencers—the
object of our study. All lab names have been included together with all influencer names with
indegree 7 or higher. Edge thickness has no specific meaning. To properly visualize the net-
工作, only profiles with indegree 2 and belonging to the main component have been taken
into account. The network in Figure 1 consists of 3,096 节点, including labs and influencers,
和 13,785 边缘.

数字 1 identifies two main clusters by size, corresponding mainly to British entities in the
upper part and French entities in the lower part. The United Kingdom cluster comprises UK
labs and the Irish lab (DCCStudio), and is next to the center of the network in closer

connection with other countries. This cluster includes the most relevant influencers, 作为
indicated by labels on the map. nesta_uk and FutureGov are two of the most prominent influ-
encers, as recognized by the EC report and confirmed by their position on the map. 清楚地,
nesta_uk holds a more central position in the European ecosystem than FutureGov, 这是
more central to the British cluster.

Note that PolicyLabUK stands at the core of the British ecosystem—as would be expected
given its central role within the UK government’s Cabinet Office—which implies that it is
situated at a very high level in the administration. Influencers detected in this cluster include
British government units and departments, such as innovateuk, the UK’s innovation agency
funding ideas in science and technology; cabinetofficeuk, the Prime Minister’s office;
UKParliament; hmtreasury, the UK Government’s economic and finance ministry; beisgovuk,
the UK Department for Business, Energy and Industrial Strategy; and mhclg, UK Ministry of
Housing, Communities and Local Government. This shows affiliations to departments that
can act as clients, 用户, 资助者, or regulators of lab activities, among other roles.

From the nonprofit sector, the Open Data Institute (ODIHQ) is identified as an important
influencer in its work with companies and governments to build an open, trustworthy data
ecosystem. The same stands for designcouncil, an institution focused on design at all levels,
from grassroots to government, developing training programs and research.

Who influences policy labs in the European Union?

Within the same cluster, we find labs of importance in the UK’s devolved regions: iLab_NI,
the public innovation laboratory of Northern Ireland, which was set up in 2014 in the govern-
ment’s Finance Department to innovate in developing public services; ylabwales, a Public
Services Innovation Lab for Wales, which emerged from a partnership between Nesta and
the University of Wales at Cardiff; or creativescots, a public body that supports the arts, 屏幕,
and creative industries in Scotland. It also includes Irish profiles, such as DubCityCouncil and
DCCStudio.

The present study reveals the importance of significant individuals as influencers, given the
greater mobility of people across countries and organizations. Within the Anglo-Saxon cluster,
the most significant individuals are Dominic Campbell, CEO of FutureGov, and Andrea
Siodmok, Deputy Director at the Cabinet Office responsible for Policy Innovation across the
UK Government through Policy Lab, the Open Innovation Team, and SKYrooms innovation
空间. The latter was also connected to designcouncil, an organization committed to improv-
ing life through design and collaboration across institutions. Not directly linked to labs, 我们
also found the economist Mariana Mazzucato (MazzucatoM), an economist and Director of
the Institute for Innovation and Public Purpose at University College London; Tim Berners-Lee
(timberners_lee), the inventor of the World Wide Web; and Philip Colligan, from the Raspberry
Pi Foundation. The last two are involved in the digital world. Close to the center of the network
we find Christian Bason, ex CEO of Mindlab, the Danish policy lab, and Geoff Mulgan, Chief
Executive of Nesta, the most influential and connected influencer of the other European Labs.

Influencers from the United States are found in near central network positions in this area.
They are the most relevant from countries outside Europe. Central positions are indicative of
shared connections with labs from other European countries, as seen in Figure 2. 二

academic labs with high social impact are TheGovLab, a lab belonging to New York Univer-
城市, and the Parsons Design for Social Innovation and Sustainability Lab (desisparsons), 一个
action research laboratory at The New School in New York.

全球范围, we can conclude that the Anglo-Saxon cluster includes the more influential pro-
files. Outside of this, other national clusters can be observed. The biggest is the French cluster,
which remains relatively isolated from another cluster made up of various Southern European
and Nordic countries.

The United Nations (和) and the EC (EU_Commission) are both intergovernmental orga-
nizations that are placed in central positions. The 27e Région (La27eregion) is the most influ-
ential French influencer, as can be seen by its position closer to other European labs and not at
the core of French institutions. It is a public transformation lab for the design of public policies.
openlivinglabs is the Twitter profile of the European Network of Living Labs (ENoLL), an influ-
ential actor in social innovation and cocreation practices across private and public
组织.

数字 1 shows how network analysis can be an effective approach to reveal the complex
ecosystem built around European policy labs. As we will examine below, this ecosystem goes
beyond the actor identified in the EC report taken as the starting point for this research.

5.2.

Influencers Identified on Twitter

Our RQ2 refers to the profile of influencers on Twitter and whether or not they match those in
the EC report. To answer this, we started with the 39 policy labs with a presence on Twitter
(including the EU Policy Lab). These labs have mean figures of 21,633.4 followers (SD ±
57,345.6), 1,052.8 friend accounts (SD ± 1,064.6), 和 7,100.67 published tweets (SD ±
10,218.73). To focus on the most important influencers, we considered profiles followed by
policy labs with a higher indegree—that is, those profiles followed by a larger number of labs.
We used indegree 6, 包括 106 profiles, to examine influencers. This increased the initial
number of 51 profiles (indegree 7), which have been named in Figure 1. The researchers clas-
sified these profiles by country and organization type.

The data show that a majority of profiles (57%) are located in the United Kingdom,
followed by France (16%) 和美国 (12%). 一些 5% have a European reach
和另一个 5% a global reach. The other countries in the sample with 1% 或者 2% are Australia,
加拿大, 丹麦, 爱尔兰, 和德国. 的 106 profiles, all use English in their descrip-
系统蒸发散, except the French accounts.

The distribution by profile type is government institutions (32%), experts (20%; 其中
仅有的 29% are women), and nonprofit organizations (18%). We found a lower presence for
商业 (8%), 媒体 (7%), networks and international organizations (6%), academia
(3%), 和别的 (8%), which included heterogeneous profiles such as conferences, 事件,
and internet services.

的 106 most-followed profiles, only three are influencers identified in the EC report:
Nesta, FutureGov, and La 27e Région—although this rises to five if we incorporate people
directly linked to organizations as indicated above. 桌子 2 shows descriptive data for the
Twitter profiles of the 15 main influencers detected. The table also shows the evolution of
rank-order positions over 1 year to determine their stability in time. Indegree was quite stable
with a slight general fall, but eigenvector centrality provides more information. Christian
Bason, former CEO of Mindlab, lost influence, probably due to the closure of the lab, 哪个
no longer appears in the list because its Twitter profile was removed. Hootsuite has a very low

eigenvector, indicative of the fact that, despite being followed by many policy labs, its impor-
tance in the community is nil as it does not belong to this group. Its presence is probably
explained by the policy of promoting account-following among Twitter users, which could
happen if labs use the tool to manage social networks. The majority have been active for
10 or more years.

To refine our analysis of influencers, in the next section we will segment influencers accord-

ing to the public administration styles of the labs.

5.3. Policy Labs and Influencers’ Public Administration Style

RQ3 focuses on the distribution of policy labs and influencers in relation to their public admin-
istration style. According to their administration style, 的 38 policy labs in the sample
(excluding the EU Policy Lab), 14 are AS, nine NO and 15 SO. 桌子 3 shows descriptive
indicators of tweets, followers, and friends (mean and SD), of the policy labs classified by
administration style. Mean figures for publications relating to AS and SO labs are significantly
higher than those of NO labs. The AS labs have more followers (mean = 42,163.2) than either
of the other two.

桌子 4 shows the number of influencers (柱子 1) in the present study by public admin-
istration style and details those that we have geolocalized (柱子 2). To limit the total number
of countries and facilitate data visualization, we have selected only those countries with at
至少 0.2% of all geolocalized influencers, hence eliminating some Twitter profiles (柱子 3).

We used a Sankey diagram (数字 2) to explore the worldwide distribution of influencers
and determine which public administration style they belonged to and which labs followed
他们. 一些 92.1% of all connections from the AS administration style are included in the
图形. 这意味着 7.9% of the connections correspond to influencers in countries that

are below the 0.2% limit of total connections. In the SO group, this amounts to 88.7%, 哪个
indicates a higher number of connections missing in the graph given that they follow accounts
in underrepresented countries. In the sample, 51.6% of all influencers are followed by AS
policy labs, 22.6% by SO labs, 和 17.2% by NO labs.

The right-hand side of the graph indicates the countries where the influencers are located:
The first number is the percentage of total influencers of the administration style to which the
country belongs; 第二, the percentage of influencers of a country over the total number
of influencers in the sample. 例如, 57.1% of all influencers of SO policy labs are
French and this represents 14.9% of all influencers in the sample.

桌子 5 shows the percentage of influencers by country and administration style. The top
三 (英国, 43.83%; 法国, 14.86%; 荷兰, 7.6%) correspond to countries
from the three administration styles of the policy labs in the sample. The fourth position is held
by a non-European country (美国, 7.54%). There are only two Germanic administra-
tion style countries (瑞士, 0.86%; 德国, 0.62%), with very low representation. 这
majority of influencers are AS (60.79%), followed by SO (20.94%), NO (16.65%), 和
Germanic (1.62%).

数字 3 shows the worldwide distribution of influencers (朋友们). There are of 28,032
unique influencers in 170 国家; due to the wide range of values, this figure is presented
using a base 10 logarithmic scale. The results show that from a European perspective the ref-

6. DISCUSSION AND CONCLUSIONS

This study uses Twitter to explore the public innovation ecosystem of European policy labs to
gain a better understanding of public innovation communities and the extent to which they are
connected to the different public administration styles. As the OECD (2019, p. 13) indicates,
the need and the potential for innovation in the public sector is greater than ever, due to a
redefinition of the relationship between governments and their constituents using instruments
such as internal innovation labs (Mergel, 锣, & Bertot, 2018). We took as our starting point
a report commissioned by the EC to identify 64 laboratories and their main influencers. 给定
the linguistic and national diversity and the different administrative styles within the EU, SNA
helps to shed light on this complex innovation ecosystem.

数字 1 confirms the existence of national ecosystems integrated in a global network, 在
which actors corresponding to the AS sphere, particularly the United Kingdom, have a special
influence. The highest number of all the influencers detected is from the United Kingdom
(43.8%). Together with 7.7% from the United States, this means that more than 50% 的
influencers detected correspond to entities from countries with an AS administration style.
Focusing on the top 106, the figure rises to 69% for these two countries. The AS style is marked
by greater adoption of private sector practices, which constitute the breeding ground for
innovation laboratories, favoring the adoption of policy labs and institutions linked to public
创新. This is confirmed by the influence in terms of both number and relevance of the

AS profiles in our study. 此外, despite the fact that actors in the network tend to follow
profiles from their own country and culture, the largest number of followings outside their
environment are with entities from countries with an AS administrative style. Given that influ-
encers act as important connectors to generate and disseminate innovations, there is a result-
ing globalization of AS administrative practices through the proliferation of policy labs. 作为
shown by previous studies applied to the municipal sphere and topics, such as e-government
and public innovation (Bolívar, 2018; Bonsón & Bednárová, 2018), administrative style can
explain differences between countries. This strong predominance of AS influencers reinforces
our earlier view and could be explained by the fact that public innovation delivered by policy
labs is more closely aligned to features of administration style, such as openness to public
sector reforms, high transparency, and citizen engagement (Torres, 2004).

The influence ecosystem revealed by SNA using Twitter data is different and more complex
than the results of the EC report, confirming the validity of this method to supplement opinions
offered solely by experts. Another important difference is the percentage of AS influencers:
38% in the EC report and 61% according to Twitter. This strong influence, exerted especially
by the United Kingdom, needs to be considered in relation to the consequences of Brexit. 它
means that most policy lab influencers and, 推而广之, public innovation influencers as a
whole, are currently outside the EU.

The network in Figure 1 shows how some institutional profiles such as those of the UN and
the EC are located in very central positions, connecting the two main clusters (团结的
Kingdom and France) and other smaller clusters such as those of southern countries (西班牙
和意大利) and northern countries (荷兰, 丹麦, and Sweden). The network offers
opportunities to develop a more powerful and interconnected network of policy labs that
boost public innovation in the EU. If the intention is for public innovation through policy labs
to be based on collaboration, more institutional efforts are needed to coordinate and exchange
best practices and projects across different countries and administrative styles.

Only three influencers (Nesta, FutureGov, and La 27e Région) 在......之外 13 are identified as
“big nodes” in the network. 然而, within the top 15 influencers we did identify related
profiles of individuals (例如, Geoff Mulgan and Dominic Campbell). The presence of experts
is very significant among top influencers: 21 在......之外 106 (20%). A certain degree of mobility of
experts across countries and organizations has also been observed. 例如, after the
closure of the Danish Mindlab, former CEO Christian Bason occupied a highly relevant
position with the Design Center project, and Jesper Christiansen moved from MindLab to
Nesta. This indicates that influence should be understood not only at an institutional level,
but also based on personal relations within a dynamic and changing ecosystem. Policy lab
practices may foster an emulation effect (Tõnurist et al., 2017), which also contributes to
the flow and exchange of people. 最后, in relation to the experts a gender bias clearly exists,
as only 29% are women.

Digital culture is quite strongly connected to policy lab influencers, as illustrated by the
significant position within the network of Tim Berners-Lee, the creator of the World Wide
Web, and by the types of activity conducted by organizations such as Nesta. Digital culture
and innovation practices have grown in parallel in recent decades. The online presence of
laboratories is undoubtedly important given their interest in promoting participation and inno-
vation in the development of public policies, including the adoption of tools and strategies
typical of Web 2.0 (Nam, 2012). 实际上, one of the policy recommendations is the importance
of generating an open digital communication policy that maximizes the impact of the entity’s
行动, both nationally and internationally.

Who influences policy labs in the European Union?

At a national level, regardless of the level of decentralization, there is a clear imbalance in
the development of policy labs in Europe. A more proactive policy is needed in the field of
public innovation to institutionalize venues and spaces for innovation. At the EU level, the EC
has an opportunity to promote and lead an ecosystem, coordinating national efforts to develop
a model that is compatible with the various administrative cultures of the member states. 在这个
感觉, the EC should also review methodologies such as SNA for the identification of commu-
实体. This study could offer exploratory methods to expand the identification process by using
hybrid approaches based on network and content analysis.

最后, it should be noted that as can be seen in Figure 3, from a European perspective,
influencers are located almost exclusively in Europe and North America. This shows that there
are opportunities to open the focus to other regions, such as South America, 其中有一个
vibrant innovation ecosystem, thereby fostering international cooperation to learn from initia-
tives in other countries and transfer good practices developed in Europe.

6.1. Limitations and Future Research

We should acknowledge some limitations of the present study. Our study focused on the
EC report on policy labs, which in itself contained the aforementioned limitations in terms
of its identification of policy labs and their representativeness. The report was an ade-
quate starting point to initiate this line of research, but recognizing these limitations should
help us understand some of the results—for example, the clear bias towards a strong AS
presence and a weak Germanic presence. The use of English as the lingua franca of inter-
national communications is also a factor that needs to be considered when interpreting
结果. 此外, the use of visualization techniques to balance the relevance of
information and its comprehension has led us to take decisions that might differ in other
案例.

As we have explained in our results in relation to RQ3, given that only countries with at
至少 0.2% of total influencers were included in this analysis, the opportunity exists to
explore influencers on a smaller scale in specific countries. 例如, 11.34% of poten-
tial influencers with the SO administration style were excluded from more detailed analysis.
The aggregated distribution of some of these influencers is shown in the map in Figure 3.
This opens up opportunities for future research aimed at discovering influencers in linguistic
areas of influence, for example of Spanish in Latin America. 此外, the methodology
used in this paper could be adapted to discover new policy labs or influencers at EU level or
in countries such as Australia or the Dominican Republic, which already have a strong pres-
ence in our sample.

To conclude, SNA seems to be an appropriate methodology to decipher the intricacies of
public innovation ecosystems, given that they are network-like models of public governance
(Scupola & Zanfei, 2016). 相似地, in our view it is an adequate approach to address the lack
of knowledge regarding Transnational Public Sector Knowledge Networks (Dawes & Gharawi,
2018). The results of this study show the promising applications of this method to advance
knowledge of emergent topics such as public innovation, which potentially involves partici-
pation by all citizens and organizations.
