Research on the Spatial Spillover Effect of Carbon Emission Trading on Carbon Emission Intensity

This article is based on panel data from 30 provinces in China from 2006 to 2019, analyzing the spatial spillover effects of carbon emission trading on carbon emission intensity through spatial econometric models. The empirical results indicate that China's carbon emission efficiency has significant regional differences and spatial correlations. Carbon emission trading can significantly reduce the carbon emission intensity of the treatment area, while also having a suppressive effect on the carbon emission intensity of surrounding areas. Based on the above conclusions, this article suggests promoting the opening and innovation of the carbon emissions trading market, increasing monitoring and control of the negative impact of carbon emissions trading, and promoting the optimization and improvement of carbon emissions trading policies.
