Abstract:This paper takes reducing resource dependence as a starting point,takes resource-based cities in China as samples, and adopts different-phase differential method (DID) to investigate the impact of carbon trading market pilot on resource dependence of resource-based cities in view of the different pilot periods of carbon trading in different pilot regions. The empirical results show that carbon trading can significantly reduce the dependence of resource-based cities on traditional resource land, but this kind of influence has hysteresis, the results of parallel trend test and placebo test can support the empirical results. The conclusion of this study will play a positive role in enhancing the confidence of China's carbon trading market and promoting the green and low-carbon transformation of regional economy.
