1. Introduction
The study of the relationship between green technology innovation and corporate financial performance can provide valuable insights into sustainable innovation strategies for managers (
Frempong et al. 2021). As the issue of global environmental degradation attracts scholars’ attention, it is also a widespread concern of firms and policymakers (
Su et al. 2021). A growing number of entrepreneurs are becoming aware of their dependence on the environment. As a result, they are more heedful of financial returns and their contribution to the society and environment (
Akbar et al. 2021). Considering the stakeholders’ requirements and institutional environmental pressures, the link between environmental sustainability and corporate financial performance is catching the spotlight (
Rabadán et al. 2019;
Jan et al. 2019;
de Padua et al. 2020). It is believed that this link is essential to the commercial success (
Chen and Liu 2018). Consistent with these developments, the relationship between green technology innovation and corporate financial performance currently occupies a prominent position in the broad research community (
Wang et al. 2021;
Ma et al. 2021;
Li et al. 2021). For example, the existing literature on some topics deals with this relationship including environmental regulations (
Ren et al. 2022), proactive environmental strategy (
Ahmed et al. 2021), eco-innovation (
Salim et al. 2019), environmental innovation (
Ren et al. 2021), and corporate social responsibility (
Sardana et al. 2020). Although hundreds of studies on this topic are in existence, the findings have been inconsistent and disappointing, most of which considering the relationship between green technology innovation and corporate financial performance to be positive (
de Azevedo Rezende et al. 2019;
Lin et al. 2019), which can not only bring benefits to consumers and firms, but also significantly release the environmental burden (e.g., in energy conservation, pollution prevention, waste recycling, green product design, and environmental management). However, other studies have shown that this relationship is negative (
Baah et al. 2021a), U-shaped (
Riillo 2017;
Jin and Xu 2020) and inverted U-shaped (
Deng and Li 2020;
Zhang et al. 2020).
In addition, previous studies consider the theoretical predictive motives of the relationship between green technology innovation and corporate financial performance. Scholars have proposed four dominant theories for studying the relationship, namely resource-based view (
Russo and Fouts 1997), legitimacy theory (
Preston and O’Bannon 1997), institutional theory (
Aguilera-Caracuel and Ortiz-de-Mandojana 2013), and stakeholder theory (
Weng et al. 2015), all of which have been used in the literature on the relationship. The resource-based view provides a tool for environmental innovation researchers. It clarifies the relationship between internal resources, technological capabilities, and performance, which forms the basis for a holistic discussion of the relationship between green technology innovation and corporate financial performance (
Cheng et al. 2014;
Tariq et al. 2019;
Johl and Toha 2021). Moreover, legitimacy theory holds that public disclosure of environmental and social information for a way of the firm’s continued existence or legitimizing to society (
Gray and Lavers 1995). Scholars have suggested that environmental disclosure can positively or negatively influence financial performance and profitability by building on legitimacy theory (
Neu et al. 1998). For example, the authors who find a negative relationship argue that disclosing CSR is a disadvantage for stakeholders since firms must expend significant resources in fulfilling their social responsibilities (
Preston and O’Bannon 1997). However, other scholars argue that legitimacy pressure significantly impacts green innovation and positively influences corporate financial performance (
Li et al. 2017;
Nguyen et al. 2021). Thus, the theory also provides a comprehensive theoretical perspective to study the relationship between green technology innovation and financial performance. Furthermore, institutional theory suggests that a firm’s environmental management practices and policies also depend on its national institutional context (
Kostova and Roth 2002). The effects of green innovation on a firm’s financial, social and environmental outcomes are equally likely to be highly influenced by the national institutional context (e.g., environmental regulatory and normative dimensions) in which the firm conducts its activities (
Li et al. 2017;
Zhang et al. 2021). Besides, another compelling argument behind the motivation of firms to engage in green technology innovation is based on stakeholder theory (
Baah et al. 2021b). Increasingly, firms use green technology innovation to promote socially responsible action and respond effectively to stakeholder needs (
Weng et al. 2015). These existing studies are critical for academics and businesses working on sustainable innovation (
Cupertino et al. 2021).
With this in mind, we want to get a comprehensive understanding of the contributions of the literature on the relationship between green technology innovation and corporate financial performance in the academic field. Specifically, we wonder about the following research questions: (i) Is the number of relevant publications still growing? (ii) Who are the influential contributors to this field? (iii) Which countries, research institutions, and journals are the most active parts of this study? (iv) What are the field’s knowledge clusters of research hotspots? (v) What are the research frontiers and trends in the field? Although several scholars have reviewed the existing literature on some topics, such as green innovation (
Albort-Morant et al. 2017;
Yin et al. 2018;
Karimi Takalo et al. 2021), green and low carbon technology innovation (
Shi and Lai 2013), sustainability innovation and financial performance (
Alshehhi et al. 2018;
Bartolacci et al. 2020), environmental innovation impacts on financial performance (
Molina-Azorín et al. 2009;
Albertini 2013;
Hizarci-Payne et al. 2021), and corporate social responsibility (
Ye et al. 2020;
Losse and Geissdoerfer 2021). However, to our knowledge, there is still limited systematic bibliometric review covering these issues on the relationship between green technology innovation and corporate financial performance. In particular, focus on the perspective of corporate financial performance and the help of computer software such as Citespace. Therefore, to address this critical research gap and deal with the above questions, we conducted a quantitative bibliometric analysis of the relationship between green technology innovation and corporate financial performance with the help of Citespace tool. By obtaining a sample of publications from the Web of Science database and visually analyzing 251 articles on their relationship from 2007 (the first article was published;
Russo and Fouts 1997) to 2021, in doing so, we offer a holistic, systematic, and scientific review of this field.
The rest of the paper is structured as follows.
Section 2 conducts materials and methods.
Section 3 presents the results and discussion.
Section 4 summarizes the main findings. In
Section 5, our contributions, limitations, and directions for future research are given.
4. Conclusions
This paper presents a bibliometric analysis of developments in research on the relationship between green technology innovation and corporate financial performance based on 251 articles from Web of Science using the Citespace tool. Based on our analysis, some conclusions can be drawn: (i) the literature on the relationship between green technology innovation and corporate financial performance first appeared in 2007 and has seen a surge in the number of publications since 2015, with 54 papers published between January and September 2021 alone, indicating that this field of research is receiving increasing attention from scholars; (ii) Yaw Agyabengmensah is the most productive author, whose works are highly collaborative with other writers and have a variety of subjects. However, there is only a small collaboration network among other authors; (iii) China is the largest research country, followed by Spain, Pakistan, and England. It indicates that focusing on the relationship between green technology innovation and corporate financial performance has become a common concern in developed and developing countries and is a research interest for scholars worldwide. Dalian Maritime University, Hong Kong Polytechnic University, and Sichuan University are highly productive institutions, but they do not work closely with other institutions; they operate relatively independently in this field. It indicates that institutions should further establish deeper collaborative relationships across disciplines and regions. In addition, the Journal of Cleaner Production is the most productive journal with 40%. The second-highest ranking is Organization & Environment with 20%, which indicates that the literature on the relationship between green technology innovation and corporate financial performance is concentrated in these top journals, indicating that these journals have a unique influence in the field; (iv) we also find that the keywords “financial performance”, “environmental performance”, “green innovation”, and “product innovation” are the hot spots for scholars to focus on in this field; and (v) “green innovation”, “corporate performance”, “legitimacy”, “environmental disclosure”, and “corporate sustainability” these concepts are expected to be new directions for further research on the relationship between green technology innovation and corporate financial performance.
5. Contributions, Limitations and Future Research
We have contributed to the study of mapping and visualizing the relationship between green technology innovation and corporate financial performance in three ways. First, our findings contribute academic value to the bibliometric research on the relationship between green technology innovation and corporate financial performance. There is a lack of bibliometric analysis in previous studies that comprehensively and scientifically evaluates their relationship. However, whether it pays to be “green” has been a core debate in the academic circle. Our study is the first comprehensive and holistic bibliometric analysis of the relationship between green technology innovation and corporate financial performance. In particular, we focus on green technology innovation from a corporate financial performance perspective. Second, our findings also contribute a valuable addition to the methodological use of this research area. Previous reviews have generally taken a systematic approach (
Mazzi et al. 2016;
Hermundsdottir and Aspelund 2021). In contrast, our study uses computer software, such as the Citespace tool. We provide direct visualization of research hotspots and trends in the relationship between green technology innovation and corporate financial performance. A visualization network helps researchers gain a clearer and more transparent understanding of the field and draw inspiration from various backgrounds. Third, our research also helps those in engineering, management, and social sciences to understand the latest advances in the relationships between green technology innovation and corporate financial performance. Since we offer the most popular topics, main keywords of clustering, and focal areas in this field.
In addition, we recommend the firm’s policymakers in four ways: (1) firms should implement green technology innovation to improve their financial performance; (2) firms create an organizational climate that encourages green technology innovation activities to improve the organization’s environmental, social, and financial performance; (3) firms should tilt their development strategies toward green innovation. For example, they create green policies to develop their green industries, thus gaining a competitive advantage in the marketplace and gradually outperforming their competitors; and (4) equally important, firms should also note that there is value in implementing green technology innovation. It is not just for developed countries but for developing countries since it is worth paying to be green.
However, this bibliometric review also has some limitations. (1) Our choice of the database may affect the number of relevant articles. We selected literature from only a single database (WoS), although this decision is based on the fact that the articles and citations collected from the WoS and Scopus databases were highly similar. However, using other databases may increase the number of articles on the research question. Future studies may consider selecting additional databases (e.g., Scopus and Google scholar) for a bibliometric review in this field; (2) due to the wide variation in content and definitions of green technology innovation (
Hermundsdottir and Aspelund 2021), literature on other terms of this keyword may be overlooked in the search process. Future studies should fully consider the comprehensiveness and completeness of the concepts of the topic; (3) although some criteria were included in the literature search as much as possible for the literature review, there is still a certain degree of personal subjectivity, which may also be a limitation of this study (
Gonzales-Gemio et al. 2020). Future studies should adopt more objective criteria to clean and organize the literature; (4) our objective is to explore only a bibliometric analysis of the relationship between green technology innovation and corporate financial performance. We don’t take into account the resilience and risk mitigation of an enterprise in the current work. However, their connection to sustainable finance and green innovation strategies may also be fantastic. Future studies should be engaged in this debate; (5) predicting emerging areas is also widely applied in patents analysis and provides a source of equal importance for nourishing an innovation strategy. However, our study has not yet mentioned this. Future studies could carefully consider this work; and (6) a meta-analysis of the relationships between green technology and corporate financial performance may also be interesting. A meta-analysis may provide a statistical integration of the accumulated research on their relationship. Future studies could take this approach to conduct further a complete and comprehensive literature review on the relationship between green technology innovation and corporate financial performance.
