低碳城市试点政策对城市绿色全要素生产率的影响及效应
Impacts and effects of low-carbon city pilot policies on urban green total factor productivity
摘要
Abstract
The low-carbon city pilot(LCCP)policies are the important content of the national low-carbon strategy,which is of great significance in upgrading industrial structure and realizing high-quality economic development.Based on the panel data of 278 cities at the prefecture level and above in China from 2007 to 2019,and taking the three batches of LCCP projects implemented since 2010 as a quasi-natural experiment,this paper adopts the methods of staggered difference-in-differences(DID),event study,synthetic DID,and generalized synthetic estimation to assess the impacts of LCCP policies on green total factor productivity(GTFP)of Chinese cities and its underlying mechanisms.Specifically,technological innovation,industrial structure upgrading and rationalization,and industrial agglomeration are selected as the intermediate mechanism variables,while factors such as factor allocation,financial development,financial efficiency,informatization,marketization,and environmental regulation are controlled.The results reveal that the LCCP policies can enhance the level of urban GTFP,but this impact is significantly heterogeneous across regions.Further analysis finds that industrial structure upgrading acts as a mediator in the LCCP policies;technological innovation and industrial agglomeration serve as moderators with promoting effects;and industrial structure rationalization functions as a moderator with inhibiting effects.Dynamic effect analysis shows that the average treatment effect after the implementation of LCCP policies is positive and statistically significant,indicating that the LCCP policies exhibit a certain lag,and the treatment effect gradually increases over time.This paper aims to provide empirical support for evaluating the implementation effect of LCCP policies and continuously advancing the national low-carbon strategy while providing useful references for promoting high-quality economic development and realizing the"dual-carbon"goals as soon as possible.关键词
