Abstract

:
Green finance is significant since it is the first organized effort by the financial industry to link financial performance with a positive environmental impact. Green finance products are being developed appropriately to achieve sustainability. The present study employs a fundamental bibliometric methodology to assess the current state and progress of academic research on green finance. 1748 papers are taken for this study. Data are extracted from a scholarly database i.e., SCOPUS and for network analysis, VOSviewer software is used. The present paper is focused on six research questions. Information is gathered to examine the above research questions and network maps are applied. We examined year-wise document publications, types of documents, subject areas, most influential articles, different journal sources, co-authorship of countries, and co-occurrence of keywords of green finance. We categorized keywords into clusters and discovered new trends in green finance. The paper also highlighted the recent issues and challenges. The study has also certain limitations and it is concluded by providing implications and suggestions for future studies. At last, this paper will give more insights to researchers, academicians, and others to discover the research gaps in this field of green finance.

1. Introduction

The global financial crisis (2007) collapsed the backbone of the international financial system. The financial crisis highlighted the recent trends in conventional finance toward the exclusive concentration of earnings in a concrete sense. The result was a loss of faith on the part of the public institutions toward the lending financial institutions (Morano et al. 2020). To bridge the trust among the investors, the lending financial institutions started implementing new approaches. The public’s interest in finance in green investment, socially responsible investment, and social impact investment are among these strategies that are progressively expanding (Morano et al. 2020; Rizzello et al. 2016; Sibanda 2013). The twofold exposure framework demonstrated that there was an interaction between the global financial crisis and other climatic change risks (Leichenko et al. 2009). Thus, global attention has been focused heavily on sustainability and climate change (Zhang et al. 2019). As a result, green finance is significant since it is the first organized effort by the financial industry to link financial performance with a positive environmental impact. It can also be considered as one of the clear indications that the economic system has begun to adapt to the challenge of the environment at large (Berrou et al. 2019).
Since the UN 2030 agenda was unveiled in 2015, member nations have designated Sustainable Development Goals (SDGs) as their top priority. A significant level of financial means is needed for initiatives to accomplish SDGs (Pizzi et al. 2021). The Sustainable Development Goals (SDGs) are implemented in 17 prime areas, where green finance plays a significant role. The purpose of green finance, according to Soundarrajan and Vivek (2016), is to strategically include the financial industry in the transformation to minimal carbon emission and wealth optimization economies as well as in the context of addressing climate change. Promoting inclusive green finance is an essential approach to reaching sustainable development goals since it concentrates on the three aspects of sustainable development (financial, ecological, and societal) (Naz et al. 2020).
Enhanced capital inflows from the public and non-public sectors are possible through the use of green finance, which aims to advance key sustainable development objectives (Ahmad et al. 2022). Green finance serves as a link between the financial and eco-friendly sectors (Ngo et al. 2021). It can also direct the flow of capital, thereby assisting in the optimization of industrial structures (Salazar 1998). Green financial products have been developed to achieve sustainability. These items refer to financial services such as undertaking venture investment, risk assessment, and greener project activities that preserve the environment, assist professional energy preservation, and enhance sustainable development (Ding et al. 2022). According to Chami et al. (2002), green finance aids in risk management and boosts the credibility of financial institutions in the market. Green debt products are a relatively new development in financial markets. The application of this instrument in financing renewable energy projects worldwide has been established (Narayan et al. 2022; Charfeddine and Kahia 2019). By introducing the purchase of liquid fixed-income assets with the additional feature of bringing investors with a social conscience who want to rely on green initiatives in the financial market, green bonds, also known as climate bonds or sustainable bonds, are expected to signify the start of a paradigm change (Bernabé Argandoña et al. 2022; Hadaś-Dyduch et al. 2022; Lee and Lee 2022). In the Chinese regulatory framework, “green financial bonds” are generally issued by retail banks to corporate investors (Zhang et al. 2022; Ehlers and Packer 2017). The entire net income from the issuance of green financial bonds shall be used to finance green initiatives, often through the issuance of green loans for the development of green infrastructure projects (Lin and Hong 2022). Narayan et al. (2022) provide evidence of the quest for quality, with investors shifting their investments from riskier assets such as conventional and Islamic stocks to safer ones such as Sukuk and Green Sukuk. Generally, financial institutions that care about environmental sustainability deal with green financial securities on the financial market (Talan and Sharma 2019). In addition, establishing a green financial system can enable the allocation of social capital for investments in green businesses, increase corporate social responsibility awareness, and accelerate the industry’s overall transition to a greener economy (Chen et al. 2022; Mehta et al. 2020; Shahbaz et al. 2013). During the COVID-19 pandemic, this evidence was very compelling. Environmental and natural resource externalities can be addressed with the aid of market mechanisms using green finance (Narayan et al. 2022; Ghosh et al. 2022). Green and sustainable financing offers advantages and opportunities (Meher et al. 2020). Consequently, many businesses are strongly emphasizing sustainability and implementing eco-friendly business practices that are good for the environment and encourage sustainability (Desalegn and Tangl 2022).
Zhang et al. (2017) research also examined the mechanisms of geographical spillover impact and diversity in China’s eastern, middle, and western provinces. They provide a framework for choosing green funding to support regional green development by extending the study viewpoint and subject matter of financial geography. Green economic development is facilitated by green finance, and this results in green GDP growth (Wang et al. 2020). Expanding the investment and finance channels of the green industry is a key step in the development of a green economy to support the government’s guidance and support for the sector (Li et al. 2022; Du et al. 2022). Consequently, green financing can be used to accomplish comprehensive green growth as it assists in alleviating and assembling flexibility against the adverse consequences of environmental changes (Prajapati et al. 2021).
All the financial institutions were ordered to provide green products to support sustainable development. This investment strategy will help achieve the UN SDGs, especially SDG 7 (affordable and clean energy), SDG 8 (decent work and economic growth), SDG 9 (industry, innovation, and infrastructure), and SDG 13 (climate action) (Desalegn and Tangl 2022). From previous literature, it was found that green finance is termed sustainable finance (Salazar 1998; Liu et al. 2015; Lindenberg 2014; Ghosh et al. 2022; Alshater et al. 2021), and socially responsible investment by (Diener and Habisch 2022; Martí-Ballester 2015), ESG finance by (Gillan et al. 2021; Giese et al. 2019; Van Duuren et al. 2016). This study addresses the following research questions:
  • What are the current trends in research publications on green finance?
  • What publications and papers have the most impact on green finance research?
  • Which organizations, nations, and authors most frequently contribute to the field of green finance?
  • What are the primary subject areas and keywords for study in green finance?
  • What are the recent issues and challenges in green finance?
  • What areas of green finance research will be pursued in the future?

Objectives of the Study

The objective of the paper is to analyze the current trends in green finance along with details of publications, organizations, countries/nations, and the highest cited authors. The purpose is also analysis which area and keywords will be highlighted in the green finance field and address the issues and challenges.
The current paper’s structure will showcase the many sections, which will be displayed as follows: The introduction to green finance is already presented in Section 1, which mentioned the background of the study and addressed the research questions and objectives. Section 2 will be covered the methodology part. The detailed analysis and discussion will be explained in Section 3, which will cover the year and no. of publications, different types of documents, subject area, most influential articles, different journal sources, co-authorship of countries, and co-occurrence of keywords of green finance. The findings will be shown in Section 4. The conclusion will be presented in Section 5 which includes the Limitations, Implications, and Recommendations of the study. The last section will wrap up this paper with the specified references.

2. Methodology

SCOPUS is one of the most popular and broadly involved academic databases that provides leading journal articles, references, and publication details for research and development. Thus, in the present study, SCOPUS was used for the literature survey and analysis. The retrieval strategies are as follows: Database = SCOPUS; Topic search = ‘Green Finance’; Period of study = 1997 to 2023 (collected data from SCOPUS on 1 November 2022, only 9 papers of 2023 are registered). We got 1748 document results for our study. Publication outcomes were exported in text form, including citation information, bibliographic information, abstracts, and keywords.
This study breaks down the fundamental features of green finance publications predominantly from two perspectives: (1) the primary highlights, that is, the efficiency and impact of publications in light of certain bibliometric pointers such as the total no. publications (TP) and no. of citations (TC), the average citations per publication (AC),) and h-index according to the viewpoint of sources, authors, countries/nations, and organizations/affiliations; (2) this paper utilize Vosviewer to introduce the visualization network, which is useful to notify the research areas of interest and improvement patterns (Wang et al. 2020; Chen and Liu 2020).

3. Analysis and Discussion

3.1. Analysis Based on Documents

Figure 1 shows the number of publications based on the year of publication. Green Finance papers were published in 1997. As per the analysis of documents by year, it was observed that the highest number of publications was published in 2022, with 995 documents, followed by 2021 and 2020, with 373 and 171 documents, respectively. To date, it has been observed that by 2023, nine papers will be published in SCOPUS-based journals. As per the publication trend, the number of green finance papers has increased tremendously and will also grow in the near future.
As indicated by SCOPUS, we have obtained a wide range of green finance publications. Figure 2 illustrates the eight different types of documents. It demonstrates that the majority of publications are from articles with 1539, which accounts for 88.0% of all records, followed by 81 review paper publications, representing 4.6%; 64 and 52 of them are conference papers and book chapters, respectively. Of the total publications, four were books, four were notes, two were editorials, and two were short surveys, accounting for 0.2%, 0.2%, 0.1%, and 0.1%, respectively. Articles are popular choice for researchers in this field.
Figure 3 demonstrated the top 10 universities in which green finance-related papers are published.
According to the data, it was observed that the top universities published ≥ 25 ≤ 50 papers. Jiangsu University got the 1st rank in green finance publications, accounting for 48. documents, Followed by the Beijing Institute of Technology and the University of Economics Ho Chi Minh City, with 42 and 33 no. of publications. This was followed by Tokai University (32), City University of Macau (29), Nanchang University (28), Southwestern University of Finance and Economics (28), Xiamen University (27), China University of Mining and Technology (27), and Qingdao University (26).
Table 1 Lists the top 10 subject areas of green finance that involve “Environmental Science” (1048 publications which occupy 59.95% of total publications); “Energy” (632, 36.16%); “Social Science” (549, 31.40%); “Economics, Econometrics, and Finance” (487, 27.86%); “Business, Management and Accounting” (321, 18.36%); “Engineering” (281, 16.08%); “Computer Science” (134, 7.67%); “Earth and Planetary Sciences” (76, 4.35%); “Mathematical methods in social science” (69, 3.95%); “Arts and Humanities” (67, 3.83%).
We can see that several topics, particularly “Environmental Science,” “Energy,” “Social Science,” “Economics, Econometrics and Finance,” and “Business, Management, and Accounting” are relevant to the research topic of green finance. Due to the fact that numerous scientific study outputs have examined green finance from multiple angles, it may be multidisciplinary.
The top ten influential articles have shown the details of authors, sources, countries, periods, citations, and keywords in Table 2.
Table 2 reveals that out of the top 10 papers, two papers were published in the Finance Research Letters in the year 2019, the Journal of Cleaner Production also 2 publications in 2019, and two papers were from the Journal of Environmental Management was published in 2011 and 2021, respectively. The title “The way to induce private participation in green finance and investment” is the highest cited article in the field of green finance research which has published in 2019 by Taghizadeh-Hesary and Yoshino and it’s citation 233. “Public spending and green economic growth in BRI region: Mediating role of green finance” is another highest cited paper, published by Zhang et al. in the year 2021 with 186 citations and so on. These ten papers were drawn from a highly diverse range of sources, highlighting the subject’s interdisciplinary aspect once again. This information will benefit researchers in analyzing the highest-cited papers on green banking and keyword analysis, which will lead to meaningful research shortly.

3.2. Analysis Based on Sources

Table 3 showcases the top-10 prolific journals on green finance with their few metrics such as TP total no. of publications (TP), % of total no. of publications (TP%), the total citation (TC), the average citation per publication (AC), h-index and total link strength. From the above Table, it found that according to country wise both the United Kingdom and the Netherlands have an equal source of publications i.e., 3 sources of each country out of 10 and followed by the United States with 2 productive journals. Sustainability (Switzerland) is published 218 papers which is found the highest paper-published journal on green finance and followed by the Environmental Science and Pollution Research and The Journal of Cleaner Production with 180 and 58 no. of documents. Out of the overall publications, these 3 journals scored 26.0,9% and the rest was done by the other journals. It is also found that Environmental Science and Pollution Research is the highest cited journal which has 1824 citations, followed by Sustainability (Switzerland) with 1670 and the Journal of Cleaner Production with 1448 citations. Based on average citations, the following 3 journals have got the highest rank. Such as the Finance Research Letters (AC = 36.95 and TP = 22), the Energy Policy (AC = 35.19 and TP = 32), and the Journal of Environmental Management (AC = 31.33 TP = 43). The Energy Policy has the highest no. of h-index i.e., 234 followed by the Journal of Cleaner Production (232) and the Ecological Economics (220). As per the overall analysis, Environmental Science and Pollution Research have the most connected journal of green finance research with 810 total strength links. Figure 4 it is mentioned that economic modeling, climate change economics, and technology society have few no. of publications in this field.

3.3. Analysis Based on Country

The geographic distribution of publications can be determined by examining the distribution of the nations that publish in this field. From Table 4, it is evident that China, with 957 articles, has produced the most scholarly papers on the subject of green finance, accounting for 54.57% of the total publications from 1997 to 2023. This was followed by the United Kingdom (155) and Pakistan (144), accounting for 8.87% and 8.24% of the total publications, respectively. Apart from TP, total citations (TC) are more frequent in China (10,519 times), followed by Pakistan (2541) and the United Kingdom (2105 times). AC was more prevalent in Japan (25.59) and Vietnam (20.28), followed by other countries. China published the most articles on the topic, had the strongest links, and amassed the most knowledge in the area, as shown in Figure 5.
There are six clusters, and each cluster encompasses nations that undertake studies in a specific area or sub-area of green finance. In VOSviewer, the closer the two countries are to one another, the stronger is their relationship. A thicker line indicates a strong link and similarity between the two countries. In our study, China had a strong link and similarities to Pakistan, the United Kingdom, the United States, Taiwan, Macau, and Hong Kong. Countries such as China, Malaysia, Pakistan, Macau, and Turkey have recently joined a group of nations that publishes green financing. From the VOSviewer result (Figure 5) shows that in cluster 4, China had connections with 54 countries and its total link strength was 575. However, there are a few counties such as Brunei Darussalam, Chile, Denmark, Iceland, North Macedonia, the Syrian Arab Republic, and Uganda, where green finance has less popular and very few studies have been done. Moreover, the countries such as China, Malaysia, Pakistan, Macau, Saudi Arabia, Bangladesh, and Turkey have recently joined a group of nations that publishes green financing.
It is vital to note that nations with no participation are automatically removed from the network. The co-authorship between nations is indicated by the lines linking the points visible on the network map, and the proximity among the clusters reflects the volume of publications and the strength of co-authorship between the nations. This provides a comprehensive picture of how well various nations collaborate on green finance-related matters.

3.4. Analysis Based on Keywords

Table 5 lists the 20 most popular keywords in this field of study. The top three themes in the literature were green finance, sustainable development, and sustainability. Green finance promotes the sustainable development of the economy, and it is obvious that this is a topic that pertains to sustainability. A visual representation of the co-occurrence of the authors’ keywords and all keywords is shown in Figure 6 and Figure 7, respectively. As per the analysis of the author’s keywords from Figure 6, it is observed that the “green intellectual capital”, “carbon emission efficiency”, and “green bank” had fewer occurrences and the highest occurrences in “green finance”, “sustainable development” and “sustainability”. However, all keywords network analysis has also shown in Figure 7 where “green finance” and, “sustainable development” along with carbon emission, environmental economics, economic development, and ecological innovation was found highest occurrences and less in “sustainable investment”, “low-carbon finance”, “low-carbon investment”. The study of keywords revealed significant data that can be utilized to explain the basic aspects of green finance. Green policy implications should govern green finance because it is linked to green investment, green growth, and climate variability. The focus areas revolve around financial development through sustainable finance, climate finance, investment in green bonds, and green innovation. Econometricians and financial economists must contribute to the field of green finance as well as to environmental economists and scientists to achieve sustainability.

3.5. Analysis Based on Authors

Table 6 lists the top 10 most productive Co-citation authors along with their connections.
When the authors of two publications receive a citation from the same author in a third document, it is known as a co-citation network of authors (Baber and Fanea-Ivanovici 2022). Consequently, co-citations jointly determine the number of documents cited. When conducting a co-citation analysis, the ‘cited authors’ unit of analysis can be used to determine the most significant (Galletta et al. 2022). Table 6 contains the supporting numerical information for this analysis. Based on our experience, five major clusters were identified, as shown in Figure 8. Cluster 1 (red) which consisted of 483 cited authors, cluster 2 (green) which consisted of 234 cited authors, cluster 3 (blue) consisted of 139 cited authors, cluster 4 (yellow) and cluster 5 (black) consisted of 131 cited authors and 13 cited authors, respectively. The outcomes of cited authors we got from VOSviewer while considering 1000 as the minimum no. of citations of an author. In addition, the top 2 cited authors of each cluster were listed below. The red cluster (Top authors: Lee, Zhang), green cluster (Top authors: Shahbaz, Charfeddine), blue cluster (Top authors: Taghizadeh-hesary, Mohsin), yellow cluster (Top authors: Yoshino, Managi), and black cluster (Top authors: Ding, Shahzad).

3.6. Analysis Based on Issues and Challenges in Green Finance

Apart from this, various issues and challenges regarding green finance have also been noticed in existing studies. Different countries have highlighted their critical issues and challenges in financing green projects. For example, mismatched interests of investors, high borrowing costs, and counterfeit assurances of environmental compliance are some challenges faced by Indian investors while investing in green finance (Chhaochharia 2021). Green financing in China confronts four primary difficulties. Such as the absence of policy directives, a lack of capacity building, unsuitable financing terms for long-term projects, and the absence of a general definition for “green assets” (Lee 2020). From the perspective of Malaysian bankers, the feasibility of the project to be funded, a lack of a track record, and a lack of familiarity with green technology are the top three key obstacles to the success of green technology financing (Amran et al. 2018). The study findings of Zheng et al. (2021) also suggested that the substantial barriers to the growth of green finance in Bangladesh include a high default culture, operational self-sufficiency, lack of proper legal responsibilities, inaccurate evaluation of loan applications, and a lack of effective accountability and transparency and inadequate corporate governance. The following issues are also examined from the study of Fedorova (2020) as being specific to green finance: discrepancies in the interpretation of the terms “green finance” and “green economy sectors,” challenges in measuring and evaluating the external effects of green finance, institutional barriers to the growth of green finance, information asymmetry, and issues with the prediction of credit and market risks.

4. Findings

According to the 1st research question, there is a noticeable increasing trend in the number of documents indicating that interest in the study of green finance performance is growing. The number of publications and citations has rapidly increased.
To assess the 2nd research question, the top ten authors and journals with their parameters are shown in Table 2 and Table 3, respectively. “The way to induce private participation in green finance and investment” was found to be the most trending paper which has been published in the Journal of Finance Research Letter and Sustainability (Switzerland) and secured the top most published journal with 218 publications.
According to the 3rd research question, Jiangsu University (China) contributes the most to green finance. As shown in Table 4 and Figure 5, China has published the most publications, the strongest connections, and accumulated the most expertise in the green finance field. The author is a significant player in demonstrating the research potential and assessing the development of an academic issue (Baber and Fanea-Ivanovici 2022). The evaluation of the author’s collaboration demonstrated the subject’s potential for further studies related to green finance. Mohsin, M, Wang, Y, and Taghizadeh-Hesary, F are the most cited authors from the outcomes of authors’ co-citation network analysis in the green finance paper with citations of 1168, 1167, and 1161, respectively, as figured out in Table 6 and Figure 8. During the investigation, it was discovered that many authors prefer to collaborate with a small number of people, leading to many significant author groups from 1997 to 2023.
As per subject area studies, it is observed from Table 1 that Environmental Science (1048), energy (632), and Social Sciences (549) have the greatest impact on green finance research, contributing 59.95%, 36.16%, and 31.40%, respectively, from the total publications. It is also found that shortly “Economics, Econometrics, and Finance,” and “Business, Management, and Accounting” areas will play a prominent role in this field of research.
A network map of the authors’ keywords (Figure 6) and all keywords (Figure 7) will be beneficial to academics for a detailed analysis of the green finance field. As per the outcomes from VOSviewers, more studies have been conducted using the keywords sustainable finance and sustainability. “Green financial products,” “green innovation performance,” “green insurance,” “green finance gaps,” “green bank,” “green credit rating” and others are a few keywords that fewer studies have done. If researchers work in this area, they are likely to obtain meaningful outcomes shortly. It is also inferred from the prior literature that different countries experience some common issues and challenges while investing in green finance. Such as the definition of green finance, technical issues in green technology adoption, inaccurate assessment of loan applications, policy framework, and legal compliances of green finance (Chhaochharia 2021; Lee 2020; Zheng et al. 2021).

5. Conclusions

Green finance enables business in the market. The main driver of economic sustainability is the growth of the green industry. Power generation, ecological sustainability, cleaner production, and renewable energy companies have all grown as a result of green investment (Du et al. 2022). This study used a fundamental bibliometric methodology to evaluate the status and development of scholarly work on green finance. This analysis consisted of a total of 1748 publications. In order to conduct the network analysis, data were taken from the SCOPUS and entered into the VOSviewer program. This study focused on six research questions. Information was gathered to examine the research questions and network maps were applied. From the bibliometric analysis and findings, it is observed that green finance has broader aspects. It is also noticed that the trend of publication in this field has been increasing faster and China has placed a remarkable position for publication of the highest cited documents. This paper has also emphasized the issues and challenges. Moreover, the overall paper will give pertinent knowledge to other researchers to study in this field.
Few limitations in the study is faced which are outlined here. First, the SCOPUS data do not contain all relevant literature; therefore, the data in this study are not comprehensive. For doable research, other databases such as WoS, google scholar, and other methodologies such as SLR and other network analyses, such as the co-occurrence of index keywords, citations, co-citations of other parameters, and bibliometric coupling, can also be applied. Secondly, only articles and review papers were employed for the analysis; however, future research could concentrate on relevant books, book chapters and conference papers to widen the scope of the data.
The results provide some practical implications for financial companies, administrators, bankers, financiers, government officials, and investors to encourage green finance for the fulfillment of the country’s sustainable development objectives (SDGs). Financial literacy in green finance is one of the keys to the inculcate public at a large. Thus, the government should take the initiative to provide information, coordinate efforts, encourage growth, and supervise green finance-related activities. To minimize the credit risk in green finance, the financial institutions should sanction loans to those investors which have good creditworthiness. Proper training should also be given to bankers, financiers, and practitioners about the operation of green technology and its applicability.
Risk and return are two major factors that affect the investor’s financial decisions. Thus, further studies can be done on perceived financial risk and expected return on green finance instruments. Nowadays financial awareness plays a significant role. As per the current scenario, a demographical analysis of different countries of financial literacy on green finance could also be proven relevant studies in this field. Apart from these, further studies could be done on different countries’ policies regarding green finance, and cross countries’ green industries’ financial performance. The above-mentioned studies can be done by applying different methodologies which will give meaningful results to researchers. Furthermore, the study may explore in green finance AI systems and blockchain analysis.
