Abstract
Despite the vitality and dynamism that the field of entrepreneurship has experienced in the last decade, the issue of whether it comprises an effective network of (in)formal communication linkages among the most influential scholars within the area has yet to be examined in depth. This study follows a formal selection procedure to delimit the ‘relational environment’ of the field of entrepreneurship and to analyze the existence and characterization of (in)visible college(s) based on a theoretically well-grounded framework, thus offering a comprehensive and up-to-date empirical analysis of entrepreneurship research. Based on more than a 1,000 papers published between 2005 and 2010 in seven core entrepreneurship journals and the corresponding (85,000) citations, we found that entrepreneurship is an (increasingly) autonomous, legitimate and cohesive (in)visible college, fine tuned through the increasing visibility of certain subject specialties (e.g., family business, innovation, technology and policy). Moreover, the rather dense formal links that characterize the entrepreneurship (in)visible college are accompanied by a reasonably solid network of informal relations maintained and sustained by the mobility of ‘stars’ and highly influential scholars. The limited internationalization of the entrepreneurship community, reflected in the almost total absence of non-English-speaking authors/studies/outlets, stands as a major quest for the field.

Notes
The Entrepreneurship Division of the Academy of Management increased its membership by 230%—more than any other established division—and with over 2,700 members, it now ranks among the largest in the Academy of Management. At the same time, the number of dedicated entrepreneurship journals listed by the Social Science Citation Index increased from one to more than half a dozen, among which the one in the lead has achieved impact factors in the same range as highly respected management and social science journals (Katz 2003; Wiklund et al. 2011).
Schildt et al. (2006).
Scopus, officially named SciVerse Scopus, is a bibliographic database containing abstracts and citations for scholarly journal articles. It is owned by Elsevier and is provided on the Web for subscribers. Searches in Scopus incorporate searches of scientific web pages through Scirus, another Elsevier product, as well as patent databases.
Campbell (2011, p. 44) argues that “[t]he academic community is geographically very dispersed and therefore has, at best, superficial social/spatial cohesion; collaboration tends to focus exclusively on task”, whereas Reader and Watkins (2006, p. 417) state that the entrepreneurship community encompasses “real and robust social and collaborative networks underlying the generation of the work which is cited jointly by third parties”.
The author deeply thanks one of the referees for proposing such an insightful method which helped to mitigate the dependence of results on the choice of entrance journals.
JCR is a database of ISI Web of Knowledge.
Number of times the articles published in a given year (e.g., 2009) in a set of journals were cited articles published in the entrance or ‘seed’ journal (e.g., ETP, JBV or SBE).
Number of times the articles published in a set of journals were cited in the entrance or ‘seed’ journal (e.g., ETP, JBV or SBE) in a given year (e.g., 2009).
In order to obtain the citation matrix of the seed journal X (ETP, JBV or SBE) in the year T (2005; …; 2009), we had to gather the citing data of each journal belonging to the citation environment of that seed journal—in the case of ETP, the average number of journals included in the citation environment was 24 (minimum of 21 in 2008 and a maximum of 27 in 2006), whereas the corresponding average was 29 for JBV (minimum of 25 in 2006 and a maximum of 36 in 2008), and 32 for SBE (minimum of 29 in 2009 and a maximum of 35 in 2006). Given that this procedure was done manually, it was rather demanding and time-consuming task.
Preference was given to Scopus, a more recent bibliographic database from Elsevier, instead of the more widely used database, the ISI Web of Knowledge, because although both are similar in coverage for the period analyzed (2005–2010), the former (Scopus) provides the name of all (co)authors of the cited studies, whereas ISI only supplies the name of the first author, limiting substantially a comprehensive analysis of top-cited authors in a given field.
In their paper, Ravallion and Wagstaff (2011) propose and discuss a new approach that is grounded on a theoretical ‘‘influence function’’ representing explicit prior beliefs about how citations reflect influence.
This does not, however, solve an important problem which consists in identifying the citation threshold above which the researcher is included in the category of ‘influential’ author. Acknowledging this important limitation, we decided to consider a rather conservative approach by computing top-50 most cited authors instead, as most common, top-10 (Frey 2006) or top-25 (Silva and Teixeira 2008) rankings.
We excluded from this figure the authors in Table 3 who have died or retired/are not active in the field (e.g., Schumpeter, Cooper, Birley, Kirzner) and those who are highly cited but are not from the area, i.e., ‘outsiders’ (e.g., Porter, Lerner, March, Granovetter, Williamson, Teece).
Since its inception, in 1996, the Global Award for Entrepreneurship Research (before 2009, International Award for Entrepreneurship and Small Business Research) has become firmly established as the foremost global award for research on entrepreneurship (Henrekson and Lundström 2009). According to Henrekson and Lundström (2009, p. 11), “a prize-worthy contribution needs to be original and influential… a contribution is influential, notably through its impact on subsequent scientific work…, by furthering entrepreneurship as a field…, by furthering entrepreneurship education and training at the academic level, and by influencing policy-making and society more broadly.”
Shaker Zahra has received several awards for his excellent service and teaching, including the Best teacher in the MBA and the Mentor Award from the Entrepreneurship Division, the Academy of Management.
William Gartner also serves on the Board of Review of JBV and JSBM.
He is also Associate Editor of The Annals of Regional Science, Journal of Policy Analysis and Management, International Journal of Technology Transfer and Commercialisation, International Journal of Biotechnology, and International Journal of Industrial Organization.
Using the ISI classification of scientific areas, demarking from the Business and Management (B&M) the specialty of Entrepreneurship (ENT), we considered 8 distinct ‘specialties’ or research subjects: Entrepreneurship (ENT), Business and Management (B&M), Economics (ECO), Sociology (SOC), Psychology (PSY), Finance (FIN), Planning and Development (P&D), and Labour and Education (L&E). It is important to note that Business and Management (B&M) includes Innovation, Marketing and Organization fields of research, whereas Accounting is included in Finance (FIN).
The other two core entrepreneurship journals, FBR and ISBJ, appear in all but one (SBE) of the seven journals.
In order to maintain the number of topic categories low, we included the Accounting-related sources that appear in FBR under the label ‘Finance’.
Detailed information is presented in Table A6 in the Online Appendix. Data was gathered from the Scopus bibliographic database (using the search machine ‘Authors’ Affiliations’) and authors'/organizations' webpages; the authors’ current affiliation reports to May 2011.
24 different countries are represented: 1 (0.5%) located in Africa; 10 (5%) in Asia; 65 (34%) in Europe; 3 (1.6%) in Oceania; and 113 (59%) in North America (it was not possible to identify the location of 5 institutions).
By May 2011 this author was also affiliated to Växjö University (Sweden).
