Can green credit policies promote coordinated emission reduction of carbon pollution? Based on a double difference model

摘要: Green credit policy is an important tool to promote the green and clean development of the industrial sector.，the transformation effect of the industrial sector directly affects the global climate governance process. To explore how green financial policies will impact coordinated carbon pollution emission reduction, this study uses the double difference model (DID) to evaluate the impact of green financial policies on coordinated carbon pollution emission reduction. Constructing an Empirical Analysis of Provincial Panel Data in China from 2008 to 2021. Results show that the green credit policy significantly inhibited the synergistic emission of carbon pollution, with a coefficient of -0.0278, and had a synergistic and significant effect on the total pollutant emissions. The mechanism test shows that the policy drives emission reduction through the path of technological innovation; however, the mechanism of industrial structure adjustment and energy efficiency has not reached a significant level. Furthermore, the policy effect is more significant in areas with high economic levels, areas with low proportions of secondary industry, and areas with high environmental regulation, revealing the heterogeneity of regional economic structure, industrial dependence, and environmental supervision on policy transmission. Based on this, we proposed some recommendations: to strengthen the regional adaptability of green financial instruments, focus on technological innovation incentives, and break heterogeneous bottlenecks through differentiated policy design to improve the efficiency of collaborative governance of carbon pollution and help promote the synergy of global climate goals and sustainable development agendas.
