Abstract:
Based on panel data from 282 prefecture-level and above cities from 2006 to 2020 and using the super efficiency SBM model with unexpected output to measure carbon emission efficiency, this study explores the impact and dynamic performance of location-oriented developmental policies represented by the "National Resource-based City Sustainable Development Plan (2013-2020)" (referred to as the "Plan") on carbon emission efficiency using a double difference model. The internal mechanism of the Plan is revealed from the perspective of industrial structure upgrading, and the heterogeneity effect of the Plan is examined. The results showed that: ① The Plan could significantly improve the carbon emission efficiency of resource-based cities by approximately 0.043 units, and this conclusion remained robust after being tested by methods such as PSM-DID. However, from the perspective of dynamic effects, a certain degree of time delay was observed in the above effects, and they exhibited a dynamic change characteristic of being strong first and then weak. ② Mechanism testing found that promoting the supererogation, rationalization, and ecologicalization of the industrial structure of resource-based cities is an inherent mechanism for the Plan to improve carbon emission efficiency. ③ Heterogeneity analysis showed that the improvement effect of the Plan on carbon emission efficiency of resource-based cities in the eastern region was significantly greater than that in the central and western regions, and this positive effect was only significant in mature, declining, and regenerative cities. Furthermore, the existence of the mechanism for upgrading the industrial structure is an important source of the aforementioned differences. The research conclusions can provide certain policy insights for resource-based cities to improve carbon emission efficiency, assist in achieving China's dual carbon goals, and promote low-carbon transformation and development.
