The impact of green financial policies on carbon emission efficiency: empirical evidence from China

In the crucial phase of high-quality economic growth, green finance is essential for directing capital to green industries and optimizing the quality of economic growth. Academics in China have paid a great deal of attention to green finance because it is a crucial government policy for advancing the development of an ecological civilization. This document examines the Chinese State Council’s implementation of the Guidance on Building a Green Financial System as a quasi-natural experiment. It determines, using the double difference method and panel data from 283 prefecture-level cities in China between 2011 and 2020, if green financial reform policies can enhance carbon emission efficiency and its mechanisms. The study reveals that green finance reform policies considerably improve the carbon efficiency of cities, albeit with a significant time lag and an annual increase in net effect. In addition, the mechanism analysis revealed that green financial policies primarily improve carbon emission efficiency by decreasing the intensity of energy consumption, enhancing technological innovation, and optimizing industrial structure. Therefore, expanding the size of the reform pilot zone and increasing incentives and guidance for green financial institutions will aid the transition of cities to a low-carbon economy.
