Out of these 47 published articles, 15 have been published in 2023, which is the highest number of publications among rest of the years. First article discussing the relationship between GHRM and Green Innovation came in 2013 which emphasized on GHRM training i.e., the part of Human Resource Management helps in the adoption of Environmental Innovation and the data for this research has been gathered from 555 manufacturing industries of Italy (Antonioli et al., 2013). A recent publication on the given topic by Awan et al. (2023) discusses the mediated-moderation approach i.e., Green Human Resource Management leads to Green Innovation which further enhances the Environmental Performance of the Firm. Green Innovation acts as a mediator whereas Green Transformational Leadership acts as a moderator between GHRM and Green Innovation, and the results show the moderator strengthens the relationship between GHRM and Green Innovation.
Years 2017–2019 show the consistent trend with (n = 1) publication each year. A steady increase in publications has been observed from year 2020 to 2023 with publications 2020 (n = 5), 2021 (n = 8), 2022 (n = 11), 2023 (n = 15). So, Fig. 2 summarizes the yearly publications of articles; 2023 with highest number of publications (n = 15). Table 1 shows the yearly citation trend and It can be seen that year 2020 has received highest number of citations yet (n = 705). Year 2019 stands second highest in the table with (n = 412) citations. Although the maximum number of articles got published in 2023 but they have not received the maximum number of citations yet. From the table it can be predicted, as publications have been increasing yearly, so the respective year will receive increase in citations on the published articles.
Journal Publication Trend
Ten main journals have been presented in Table 2 on the basis of highest number of Publications out 0f 47 selected articles. Table 2 shows the Journal name, n = number of publications, %= percentage that journal is contributing to the total of 47 publications, TC = total citations the journal has received till now, Impact Factor of that journal and the article with highest of number citations published in that particular Journal. A total of 44.68% is condensed in the Fig. 3 with respect to these 10 journal publications. Figure 3 shows the percentage of each journal out of top 10 contributing towards publication of articles on the topic of GHRM and Green Innovation. Out of top 10 journals, ‘’Environmental science and Pollution Research’’ and ‘’Sustainability (Switzerland)’’ top the table with maximum number of publications (n = 4) with 8.51% on the linkage between GHRM and Green Innovation. A journal named ‘’Technological Forecasting and Social Change’’ comes at third with total publications (n = 3) and 6.38%. Three journals have total publications (n = 2) and then the rest of the journals given in the table have only one publication with 2.13% till now.
Along with this information, impact factor of the journals has also been discussed in the table. Journals with greater number of publications may not have the high impact factor. The Journal with highest impact factor 11.072 is the ‘’Journal of Cleaner Production’’ although its publications are fewer in number. The top two journals with highest publications ‘’Environmental Science and Pollution Research’’ and ‘’Sustainability (Switzerland)’’ have impact factor of 5.19 and 3.88 respectively.

Another journal named ‘’Research Policy’’ stands out with impact factor of 9.473 but has only one publication till now. A journal with least impact factor of 0.284 is ‘’International Journal of Sustainable Development and Planning’’ but it stands at number 5 in the table with respect to number of publications.
Total number of citations received by the journal on publishing GHRM in relation to GREEN Innovation has also been mentioned in the table. Journal named ‘’Technological Forecasting and Social Change’’ has received highest number of citations (n = 1073), followed by the journal ‘’Research Policy’’ which has received (n = 158) number of citations in this selected list of journals. The article published in the journal ‘’Technological Forecasting and Social Change’’ with highest number citations (n = 509) discusses the impact of Green Transformational Leadership on GHRM which further enhances Green Innovation, so GHRM has been taken as a mediator in this research (Singh et al., 2020). Another article by Ogbeibu et al. (2020) with highest number of citations (n = 85) published in the ‘’Journal of Cleaner Production’’ with maximum impact factor discusses how some of the activities of GHRM such as green trainings, green compensations, green recruitment will affect green team creativity; ultimately that induced green team creativity among employees will help them to bring green product innovation. (The data for this research has been collected from the manufacturing sector of Malaysia). Highest citation receiving documents have been mentioned in the above table published in the respective journals.
Citation Analysis
Waltman et al. (2010) refers citation analysis as the number of times particular institute, document, country or author has received citations. Using the software VOSviewer, different citation analyses have been conducted with different unit of analyses to know the citation impact on a particular institute, author, document or country.
Institutional Analysis
Using VOSviewer, citation analysis has been performed by keeping institution as the unit of analysis. This analysis helped us to interpret which educational institution is most impactful in receiving maximum number of citations on the published article linking GHRM and Green Innovation. The criteria for the analysis have been set up as minimum number of documents per institution (n = 1) so that 151 out of 151 institutes meet the given threshold. Table 3 shows top 12 institutes with the total number of citations on published article out of 47 selected articles and it also mentions the individual citations of the articles.
‘’Abu Dhabi University of United Arab Emirates’’ tops the table with maximum number of citations (n = 921) and it is the only institute which has published two articles till now on the given topic. The article which got published first with reference to Abu Dhabi University has received 412 citations and it discusses the drivers of Green Innovation which are necessary for the competitive advantage of the firm. One of the drivers of Green Innovation discussed in the paper is HR Practices (El-Kassar & Singh, 2019). The other article of Abu Dhabi University got published in 2020 and it received 509 citations. Paris School of Business-France National Research University-Russia and University of Milano-Italy made a collaborative effort in publishing this one article in 2020 which received 509 citations. This article by Singh et al. (2020) was a joint publication by the three institutes and it discusses the mediation of Green Innovation between GHRM and Environmental Performance. Table 3 shows that University of New Mexico-United States has received least number of citations (n = 152) on an article which is also a joint publication with other universities. This article studies Green Intellectual Capital and GHRM as the drivers of Green Innovation which ultimately lead to Environmental Performance (Rehman et al., 2021). The table summarizes the top 12 institutes with maximum number of citations received on published article along with the individual article citation.

Documents’ Analysis
After running citation analysis on VOSviewer by keeping Documents as unit of analysis and selecting minimum number of citations per document (n = 5), the results show that 24 documents out of 47 meet the threshold. Figure 4 is extracted from the VOSviewer showing different clusters. Size of the cluster shows the dominancy of the article by author with respect to received citations. Figure 4 shows that article by Singh et al. (2020) dominates the figure as it is interlinked to different authors and received highest number of citations (n = 509). Table 4 further elaborates the document alongside its citations, authors and year of publication. Top ten documents have been selected with maximum number of citations. An article with number of citations (n = 114) discusses the mediation effect of GHRM between Green Transformational Leadership and Green Creativity, the variable green creativity has been discussed keeping in mind concept of innovativeness in the given article (Jia et al., 2018). Another article presented at second last number of the table with citations (n = 43) has taken green innovation culture as moderator which strengthens the relationship of GHRM and Firm Performance (Muisyo & Qin, 2021). Lastly, the document with least number of citations (n = 36) by Bossle et al. (2016) discusses the Green Innovation in Food Companies how they can opt eco-friendly innovation by important internal and external factors. One of the major internal factors discussed is HRM practices which will lead to eco-innovation in the food industry of Brazil.

Co-Authorship Analysis
As per the study of van Eck and Waltman (2014), co-authorship analysis tells us about how a particular document has been produced by two or more than two authors. This type of analysis tells us about the linkage of authors on the basis of number of articles produced by particular authors (Enciso-Alfaro & García‐Sánchez, 2023). Using the software VosViewer, this analysis can be run at the level of authors, organizations and countries.
Co-Authorship at Country Level
Using software Vos Viewer, co-authorship analysis at country level has been performed to know the collaboration of authors across different countries. Co-authorship at country level will help us to understand how a particular document has been co-authored from different origins. with some major countries showing collaboration on bringing articles on green innovation being induced by GHRM. By keeping ‘’Countries’’ as unit of analysis, minimum number of documents per author (n = 2) and minimum number of citations per author (n = 5); the results obtained after running co-authorship analysis show 13 countries out of 32 meet the threshold which shows the collaboration of authors in bringing the documents on GHRM and Green Innovation. The set criteria for the given analysis extracted Fig. 6.
As per the figure, Saudi Arabia seems to be dominating in this regard with highest co-authorship links (n = 7) with different countries i.e., Egypt, Pakistan, Malaysia, Italy, United States etc. Second highest co-authorship links (n = 6) can be seen of Pakistan with China, Saudi Arabia, Malaysia, United States etc. Three countries i.e., Malaysia, United States and Italy are seen to be showing same number of links (n = 5) with other countries. China and France show collaborations with further 3 countries with respect to co-authorship.
Table 6
Co-Authorship and Different Countries
Country | Documents | Links | Citations |
Pakistan | 15 | 6 | 209 |
China | 14 | 3 | 251 |
Saudi Arabia | 9 | 7 | 200 |
Malaysia | 8 | 5 | 148 |
United States | 4 | 5 | 237 |
Italy | 3 | 5 | 819 |
Egypt | 3 | 2 | 36 |
France | 2 | 3 | 535 |
Tunisia | 2 | 2 | 5 |
Thailand | 2 | 2 | 12 |
For better understanding of the above pictorial figure, this table is extracted which shows the documents co-authored by the respective countries, total number joint links of countries and lastly the number of citations the countries have received on co-authored articles. Table 6 shows that although Pakistan has highest number of co-authored documents (n = 15) but it has collaborative links (n = 6) lesser than that of Saudi Arabia (n = 7). The second highest number of documents co-authored are of China (n = 14) but it has 3 joint links with other countries in co-authorship. Saudi Arabia stands out in collaborative links but comes at third on number of documents (n = 9). Lastly, coming to the number of citations, Italy dominates the table in this regard with (n = 819) citations, then France (n = 535), China (251), United States (n = 237) and Pakistan with 209 citations on co-authored documents.
Bibliographic Coupling Analysis on Documents
Bibliographic Coupling analysis on documents tells us about a third common document being referred by two or more articles. Documents are seen to be sharing same cluster or group if they have greater number of overlapping references (F. Khan et al., 2022). Figure 6 is extracted by running bibliographic coupling analysis on documents as unit of analysis. Results show that 26 documents out of 47 meet the given criteria. The results are obtained by keeping minimum number of citations per documents (n = 3) an it resulted in 4 clusters and 26 items. Figure 7 shows 4 dominant colours red, yellow, blue and green. The clusters generated can be named as Cluster 1 (Red Group), Cluster 2 (Green Group), Cluster 3 (Blue Group) and Cluster 4 (Yellow Group) for better apprehension.
The inter and intra connections of references within or between groups can be interpreted from Fig. 7. Discussing red group, one of the articles by Rajiani et al. (2015) which addresses some detriments of GHRM using Ability, Motivation and Opportunity (AMO) concept, helps in process innovation in manufacturing industry of Malaysia. This article is further referred by other two documents in the same group. One of them takes innovation capacities as a mediator between GHRM and competitive advantage (Gharbi et al., 2022) and the other one addresses the role of Green Product Innovation as a mediator between GHRM and Green Supply Chain Management (Kara & Edinsel, 2022). Talking about interconnections of the groups, one of the articles in Green Group is referred by two articles in Yellow Group. Article by Yahya et al. (2021) addresses the intention of small business to go for eco-innovation by practices of GHRM in an organization and the other article in the same group by Ullah et al. (2023) talks about the impact of GHRM and Green intellectual capital on Environmental Performance with Green Innovation as a mediator. Both of these documents have referred to a common article which got published in 2020. This article addresses two factors i.e., GHRM and the concern of Management towards environment which help in stimulating Green Innovation (Song et al., 2021). So, the following figure summarizes Bibliographic Coupling of Documents which share common references.
Co-occurrence- Authors’ Keywords Analysis
Using Vos Viewer, co-occurrence analysis has been run to know how many times authors’ keywords have co-occurred with each other. Co-occurrence analysis helps us to dig into the latest research areas (Khan et al., 2022) and also identifies the gaps for future research contributions. This analysis tells us about the keyword which has been used for the maximum number of times and likewise it further shows the keywords which have been explored leas till now. The keyword used for fewer times, serves as a gap analysis for future purposes. Figure 8 shows that 28 out of 156 keywords meet the given threshold after keeping the criteria as minimum number of occurrences of a keyword as (n = 2). The figure elaborates that different keywords have been used by authors which have contributed in linking GHRM and Green Innovation such as Eco-Innovation, Environmental Performance, Green Innovation, Organizational Performance, Green Human Capital, Green Product Innovation, Training, Corporate Social Responsibility, Green Creativity, Management Commitment etc. Table 7 is extracted for better understanding of the given figure. It picks the top 20 keywords on the basis of maximum number of co-occurrences. Given in the table, Green Innovation has occurred for the highest number of times (n = 18), forming maximum number of links with other keywords. The average publication year for Green Innovation is 2021. Next comes Green Human Resource Management which has been occurred for 16 times, with (n = 16) links and averagely being publicised in 2020. Apart from the main variables of concern, the keyword which can be seen with 15 links is Environmental Performance and has average publication year of 2022. Corporate Social Responsibility has average publication year of 2023, which shows that recent work has been done on this keyword in the given domain. Occurrence of some other keywords can also be seen in the table such as Green Transformational Leadership (n = 5), Sustainable Performance (n = 4), Corporate Social Responsibility (n = 3), Management Commitment, Green Creativity and Green Intellectual Capital have occurred for 2 times.

Future Recommendations
The impact of GHRM and Green Innovation (as a mediator) can be investigated on variables other than environmental performance. Studies show that GHRM has a positive impact on green organizational citizenship behavior (Hooi et al., 2022), Green organizational identity which further lead to voluntary and task relevant green behaviors (Zhu et al., 2021), Corporate social responsibility (CSR) practices (Freitas et al., 2020), organizational commitment (Shoaib et al., 2021), energy efficiency (Lee, 2020), and economic performance (Luzzini et al., 2014). This study proposes to check the relationship between GHRM and all the above-mentioned outcome variables along with Green Innovation as a mediator.
Forty-Seven articles were included in this bibliometric analysis, majority of which take GHRM as an independent variable and Green Innovation as a dependent variable. Studies show that Green Innovation is also used as a mediator between GHRM and Environmental Performance (Fang et al., 2022; Kanan et al., 2023; Mittal & Kaur, 2023). Furthermore, past studies have also proven the mediation of other variables such as Green Creativity (Malik et al., 2021) and Green Human Capital (Munawar et al., 2022) between GHRM and Green Innovation. Currently, there is a need to study what are other internal employee factors which further lead to Green Innovation. There are some other variables which are analysed as a mediator between GHRM and some other outcome variables, such as Green Motivation as a mediator between green training and Environmental performance (Yafi et al., 2021), green passion as a mediator between GHRM and Green Creativity (Jia et al., 2018), Green self-efficacy and employee green behavior as intruders between GHRM and Environmental Performance (Nisar et al., 2022) and Psychological Green Climate as an intervening variable between GHRM and Employee Green Behavior (Srivastava & Dhiman, 2022). Our study proposes that above mentioned internal factors such as green motivation, Green Passion, Pro-environmental Behavior, Psychological Green Climate, Green Self Efficacy, should be studied whether they serve as a mediation between GHRM and Green Innovation.
Green Transformational leadership is taken as a moderator between GHRM and Green Innovation in the recent study (Awan et al., 2023). A study of Kaur and Mittal (2023) takes servant leadership as a moderator between GHRM and Product and Process Innovation. Some other leadership styles such as follower leadership, transactional leadership, ebullient leadership can be studied as a moderator between GHRM and Green Innovation. Environmental Managerial is used as a moderator between GHRM and Green Human Capital (Song et al., 2021) and Green Culture as a moderator between Green Knowledge Management and Green Innovation (Wang et al., 2022). So, these variables environmental managerial concern and green culture can be taken as a moderator between GHRM and Green Innovation.
Future researchers can also dig into the secondary research for this purpose. They can find the dimensions used to measure GHRM and Green Innovation in the annual sustainability reports of the firms. Till now primary research has been main focus in this regard, but in future secondary research can be done to investigate the relationship between GHRM and Green Innovation.
Future researchers should focus on the separate factors which constitute GHRM, such as green trainings, green compensations, green performance management, green rewards and how these factors are individually impacting Green Innovation, so one can know which is the most beneficial factor of GHRM in brining Green Innovation. Scopus database is used for this bibliometric analysis on GHRM and Green innovation, in future Web of Science should also be used to know the more contributions of researchers in the respective domain.
Future researchers can particularize the bibliographic analysis to specific industry such as investigating the relationship between GHRM and Green Innovation in Hospitality industry, manufacturing industry, services industry etc. On the basis of future recommendations, following Fig. 9 is mapped out which shows the options of variables which can be used in this regard.
