3.1 Summary of the data
This section covers brief description of the whole data that is selected for our study purpose and three field plots. Data has been gathered from last five years (2018 to 2022 and early access articles of 2023). It has been concluded that a total of 183 documents which are selected for the study contain 61 Sources such as books, journals, etc, the total number of authors is 517, and Single-authored documents have 14 authors. Total references are 13117, researchers’ keywords are 715, and 615 total keyword pluses (words that appear repeatedly or more than once in the titles of referenced publications). Figure 3 illustrates three field plots of authors, keywords, and author’s countries. Names of the top ten authors are displayed on the left field; the middle field represents the author’s keywords (n10) and the right field shows the author’s countries. Cohn B, Genus A, Fichter K, Guerrero M, Burch Si, and other renowned authors have written pieces on green entrepreneurship. The top working nations include the United Kingdom (n17), the United States (n16), Spain (n16), Italy (n15), Germany (n11), and so on. The top author’s keywords revealed various terms which include Sustainable Entrepreneurship, Entrepreneurship, Sustainability, Social Entrepreneurship etc.
3.2. Sources information
This section discusses Bradford's Law and production of sources throughout time. Figure 4 shows most relevant sources using Bradford law. Under Bradford law the total number of articles are divided into 3 groups, each consisting of one-third of all articles. The figure shows that Journals like Business Strategy and Environment, Small Business Economics, International Entrepreneurship and Management Journal, Technological Forecasting and Social Change fall under Zone One journals (i.e. Core Journals), Journals like Journal of Business Ethics, Journal of Business Research, Industrial Marketing Management fall under Zone 2 and Journals like Innovation-Organization & Management, Corporate Social Responsibility, and Environmental Management fall under Zone three journals (i.e., Secondary journals). Table 2 shares information rigorously about the growth of sources over this period.

3.3. Authors
Information is provided in this area regarding the top authors who published articles on green entrepreneurship. Table 3 shows the top ten cited documents of our study along with their titles, sources' names, years, and author’s names. (Kraus S, 2020) document entitled ‘Corporate Social Responsibility and Environmental Performance: The Mediating Role of Environmental Strategy and Green Innovation’ has recorded maximum citations (n = 308), (Cohen B, 2018) article named ‘Sustainable Entrepreneurship Research: Taking Stock and Looking Ahead’ received second highest citations (n175). Blok V’s (2018) article ‘Toward a Validated Competence Framework for Sustainable Entrepreneurship’ has 109 citations, Kraus S (2021) article titled ‘Social Entrepreneurship Orientation: Drivers of Success for Start-Ups and Established Industrial Firms’ has been ranked lowest in the below-mentioned list of top-cited documents as it received 34 citations only. Figure 5 depicts the productivity of an author using Lotka's law. The graph of the top documents written by various authors is displayed in the image. It reveals that only 1 document has been published by 472 authors on green entrepreneurship. There are only 2 documents authored by 42 authors, 3 by 3 authors, and so forth.

3.4 Top Performing Nations
Based on the nationality of the corresponding author, Fig. 6 displays the scientific findings of top twenty nations in the fields of green entrepreneurship and international collaboration in stylometry research. Single Country Publications are referred to as SCPs, and Multiple Country Publications are MCPs. From the results it has been derived that the UK, Germany and Netherlands are the countries that has published the highest number of articles and the UK, Germany, Netherlands, Spain, USA, and other nations have a large number of international alliances. Still, certain conclusions may be drawn from the MCP ratio of the twenty most influential nations, shown as a percentage of total articles. Among all countries Belgium has gained maximum MCP ratio (100%), then, Denmark (100%), New Zealand (38%), and China (80%). The ten nations with the most articles published include the UK, Germany, and the Netherlands.
Figure 7 shows trending topics between 2018 to 2022 on the basis of keywords plus in the hierarchical arrangement on green entrepreneurship that are discussed by scholars annually. These topics are related to green entrepreneurship which are used in published publications. For instance, in 2019, Institutional entrepreneurship (freq. 8), then Self-efficacy (freq. 6) and finance (freq. 5) was the most discussed. However, one year later, in 2020, Management (freq. 26), Social Entrepreneurship (freq. 10), Responsibility (freq. 10) and entrepreneurship (freq. 470), Innovation (freq. 43), Business (freq. 22) was the most discussed issue in 2021. In the year 2022, Performance (freq. 36), Sustainable Entrepreneurship (freq. 19) and Knowledge (freq.15) among the most discussed topics. From the trend it can be noticed that emerging themes of 2023 includes areas like Networks and capabilities.
With the use of VOSviewer, Fig. 8 displays a network visualising diagram of author keywords featuring a minimal occurrence over two times. Size of every bubble depends upon the times the respective keyword occurred. Maximum frequency is found in "sustainable entrepreneurship," which occurs 32 times and has a strength of the link of 154. Next in frequency are "entrepreneurship," which occurs 28 times and has strength of the link of 151, "sustainability," which occurs 24 times and has a strength link of 125, and "social entrepreneurship," which occurs 18 times and has a strength link of 83, and "sustainable development," which occurs 14 times and has a link strength of 81. According to distance analysis, which considers link quality and citation weight—both of which are dependent on frequency—keywords are divided into eight clusters in Fig. 9. The number of times a keyword has been co-selected in a publication is shown by the dimensions of the circles where it appears. The words most closely associated with strength are entrepreneurship, innovation, and sustainable entrepreneurship. The distance between two keywords shows how strong and similar in theme they are relative to one another. A comparable theme among the publications is indicated by circles of the same colour and each hue denotes a different cluster.
3.5 Conceptual and social structure analysis
This section includes Thematic Map Analysis, Co-citation networks of Authors and Institutions prepared with the help of biblioshiny (R-package) and various collaborations on publications related to green entrepreneurship among different institutions and countries. Figure 10 identifies, thematic map shows the co-occurrence network's discovered clusters from 2018 to 2022. Here, X-axis shows centrality, or how much a network cluster interacts with other clusters, and gives information on the importance of a theme. As we can see, the whole map has divided the key themes into four quadrants based on some parameters. The initial region shows motor concepts (including concepts that have developed), the second region identifies advanced and isolated concepts (concepts that are of little significance for the field), and the third quad. includes arising or reducing concepts (including concepts that have been lightly developed). Fall into fourth Quad. are fundamental and intersecting concepts or universal issues that cross over into other fields of study. Future research studies can lie in the areas that fall under the quad. four (i.e., Research and Development, Innovation, Technology, strategy, etc.). The co-citation structure of different authors is shown in Fig. 11. Here, Cluster One includes authors like Mair J, Teece DJ, Battilana J, Anonymous and Cohen B, Munoz P, and Dean TJ belongs to Cluster Two. Cluster three includes names like Stam E, Autio E, Acs ZJ, etc.
Figure 12 shows collaborations networks on green entrepreneurship between various institutions. It reveals that De Montfort Univ, Univ Kent, Univ Manchester fall under Cluster 1. Cluster two includes Coventry Univ, Univ Turi, Brunel Univ London, and cluster three includes Leuphana Univ Luneburg, Brock Univ, Univ Sussex, and so forth. Table 4 reveals that Australia and New Zealand have tied with highest no. of collaborations (n2). Austria and Macedonia share second place with one partnership, and so on.
