The Heterogeneous Relationship between Pollution Charges and Enterprise Green Technology Innovation, Based on the Data of Chinese Industrial Enterprises

The impacts of China's dual carbon policy on green innovation: Evidence from Chinese heavy-polluting enterprises

Encouraging enterprises to engage in green innovation is a potent strategy for reducing carbon emissions from production. As one of the largest carbon emitters, China has launched a series of policies to achieve carbon peaking and neutrality collectively referred to as China's dual carbon policy. However, existing research on the impact of China's dual carbon policy on green innovation by heavy-polluting enterprises is insufficient. To fill this gap, this study constructed a theoretical model to draw hypotheses about the impact of the dual carbon policy on enterprises' green innovation and verified this impact using a difference-in-differences model to conduct a quasi-natural experiment based on data from 2010 to 2022 from Chinese A-share-listed enterprises. The results indicate that the dual carbon policy had a significantly positive influence on green innovation in heavy-polluting enterprises. Moreover, environmental tax mediated this effect, while enterprises' total costs and subsidies positively moderated it. Additionally, the impact exhibited variations based on several key factors, including green patent type, carbon emissions, enterprise ownership structure, and Environmental, Social, and Governance ratings. This study supplements related research on the effects of environmental policy on green innovation and provides both theoretical and empirical support for adapting subsequent environmental policies.

Impact mechanism of environmental protection tax policy on enterprises' green technology innovation with quantity and quality from the micro-enterprise perspective

Promoting green technology innovation through environmental tax is an important tool to achieve green development. Based on the data of Chinese listed companies from 2010 to 2020, this research examines the impact mechanisms of environmental tax policies on the quality and quantity of enterprise green technology innovation from the micro-enterprise perspective. The underlying mechanisms and heterogeneous effects were analyzed empirically using pooled OLS model and the mediated effects model. The results indicate that the environmental tax policy has an inhibitory effect on the quantity and quality of green patents, and the impact on the quantity is more significant. The mechanism analysis suggests that the environmental tax inhibits green technology innovation via accelerating capital renewal and environmental investment. Heterogeneity analysis shows that environmental tax has an inhibitory effect on green technology innovation behavior of large-scale enterprises and eastern region enterprises, while it has a boosting effect on green technology innovation of western region enterprises, and its effect on quantity of innovation is greater than that on quality. This study helps Chinese enterprises to better achieve green development from the perspective of green taxation and provides important empirical basis for achieving the win-win goal of economic growth and environmental development.

Bibliometric Analysis of the Research on the Impact of Environmental Regulation on Green Technology Innovation Based on CiteSpace

With increasing environmental regulation (ER), the requirements for green technology innovation (GTI) in enterprises are also rising. However, there are relatively few systematic summaries of the themes of ER-affecting GTI. Adopting the method of bibliometrics and visual analysis, this research discusses the status of research and development trends of ER-affecting GTI and summarizes the research in this field. The paper takes 738 papers from 2001 to 2021 in the core database of Web of Science as the research sample. Based on CiteSpace, this paper makes a visual analysis of the number of published papers, institutions, authors, keywords, countries (regions) and journals. The study found that to some extent, favorable collaboration between authors and institutions in this field needs to be strengthened. Research hotspots in this field include innovation, technology, performance, policy and environmental regulation. Renewable energy consumption, the pollution haven hypothesis, sustainable development, carbon dioxide emission, energy technology and environmental Kuznets curve are the current research frontiers in this field. In terms of the number of published papers, research in this field has been conducted in a national (regional) layout with China as the core force, and Italy, America, Britain, Germany and other European countries as important forces. This field covers three main research areas: enterprise performance, policy instruments and research methods, going through the start-up phase (2001-2011), the growth phase (2012-2018) and the development phase (2019-2021). Future research can further incorporate the digital economy and synergy of multiple environmental regulation policies into this field, which will continuously enrich the theoretical research system in this field. The content, methods and conclusions of research in this field are becoming increasingly diverse.

The Mixed Impact of Environmental Regulations and External Financing Constraints on Green Technological Innovation of Enterprise

Green technological innovation is an important force for high-quality economic development and high-level ecological environment protection. Environmental regulation and market financing are important factors affecting enterprise green technological innovation, while the relationship between environmental regulation and enterprise green technological innovation is most likely to be nonlinear. Additionally, this impact may be moderated by market financing. Based on the data of 2278 manufacturing enterprises in China, this article intends to empirically test the nonlinear relationship between environmental regulation and enterprise green technological innovation. Green technological innovation is divided into green process innovation and green product innovation. Based on this, the analysis of the heterogeneous impact of environmental regulations on different types of green technology innovation is implemented. Moreover, the moderating effect of external financing constraints on the relationship between environmental regulation and green technological innovation is further discussed. It shows that there is an inverted U-shaped relationship between environmental regulation and enterprise green technological innovation. This conclusion will not change due to the types of green technological innovation, while the impact of environmental regulation on enterprise green product innovation is greater than that of green process innovation. In addition, external financing constraints will reduce the impact of environmental regulation on enterprise green technological innovation. The research conclusions have certain reference value for deepening the understanding of green technological innovation and optimizing the relationship between government and market.
