Measurement of regional green finance development and its coordination with economic development: a study on the Yangtze River Delta region of China

Abstract

The green transformation of industry and sustainable economic development both require considerable investment. In this regard, green finance that is compatible with economic development can help cope with the massive demand for capital. Taken China’s Yangtze River Delta (YRD) as an example, this study is to measure the coordination degree between green finance and economic development. First, the concept, content and scope of green finance is defined based on the new financial regulation mechanism. Second, a green finance measurement index is built to calculate the green finance index for 30 Chinese provinces by the CFA test. Third, based on the economic structure index, an economic development index is built. Testing the rationality of green financial index and the economic development index, this paper finally measures the degree of coordination between green finance and economic development in the YRD. The results reveal that, first, green finance is a financial instrument that integrates financial industry development, environmental improvement, and economic growth. The measurement of the green financial development index includes the sum of regional green credit, green investment, green securities, and green insurance. Second, after years' development, the comprehensive score of YRD’s coupling coordination degree exceeds 0.8 in 2020, which shows a high level of coordinated development between green finance and economic construction. However, there is a 2-year timing effect between the economic development and green finance index increase, which reveals that green finance development in the YRD requires further policy guidance and support. This study’s findings can provide a theoretical reference and case support for the further development of green finance and related policies in China.
