Exploring the Sustainable Development Path of a Green Financial System in the Context of Carbon Neutrality and Carbon Peaking: Evidence from China

In the 75th session of the United Nations General Assembly, the Chinese government first proposed the goal of carbon neutrality and carbon peaking. Since then, China’s economy and society have undergone a comprehensive green and sustainable development upgrade and transformation. The development of green finance can provide financial support for the achievement of the dual carbon goals and mitigate the impact of climate change, and more importantly can contribute to the sustainable development of the national economy and society. In this study, we innovatively draw on the quality function deployment theory in marketing to logically formulate the research idea of this paper. The greatest advantage of this approach is that it enhances the readability of this paper and enriches the research logic system of this paper. On this basis, we also applied the G1-entropy value method from fuzzy mathematical theory for quantitative research. In fact, it should be noted that the G1 method we propose in this study is actually an improved subjective assessment method, in which we introduce expert ratings to improve the reliability of the subjective assessment results. As we all know, financial system architecture and research is a common academic topic, but unlike the classical research on the development quality of financial systems, we innovatively addressed the actual national conditions in China and fully integrated green elements in the construction of the index system from the perspective of green finance and sustainability. Finally, we calculated the index weights through G1-entropy quantification, and qualitatively propose countermeasures for the development quality of China’s green finance for key index factors. In conclusion, we sort the contributions of this paper into the following three aspects: (1) we innovatively combined the quality function deployment theory and built the quantitative analysis process architecture in this paper, which enhanced the readability of this paper; (2) we realized the use of quantitative research for qualitative analysis and proposed the G1-entropy value method, which made up for the defects of the subjective and objective methods in the traditional evaluation methods; and (3) we realized the organic combination of quantitative and qualitative analysis, and proposed relevant countermeasure suggestions based on the quantitative index calculation results, which provided relevant countermeasure suggestions for promoting the sustainable and high-quality development of green finance in China
