低碳转型对城市经济高质量发展的影响——来自低碳城市试点的经验证据

On Influences of Shifting to Low-carbon Practices on High-quality Urban Economic Development--Empirical Evidence from Low-carbon Pilot Cities

实施低碳城市试点政策是对低碳转型战略的具体落实,评估其执行效果可以为后续稳步推进低碳转型工作提供微观经验支撑。文章将低碳城市试点政策看作是一项准自然实验,基于2008—2020年中国276个城市的面板数据,运用多时段双重差分固定效应模型开展实证性分析。研究结果表明:低碳城市试点政策在推动城市经济高质量发展方面起到了积极的促进作用,并且该政策主要通过集聚人力资本和促进绿色技术创新来实现经济发展质量的提高;异质性检验表明,该政策对位于东部和西部区域城市的经济高质量发展具有更强的驱动效果;进一步研究发现,该政策对邻地的经济高质量发展也具有积极的空间外溢效果。

The implementation of low-carbon pilot city policy is a practical step towards low-carbon transition.Analyzing its implementation can provide empirical evidence to support the subsequent promotion of low-carbon transition.An empirical analysis of the low-carbon pilot city policy in China between 2008 and 2020 is conducted using panel data from 276 cities and a multi-period double-difference fixed-effects model,and it is done as a quasi-natural experiment.The results of this study suggest that the policy has a positive effect on urban economic development,which is achieved through the pooling of human capital and the promotion of green technological innovation.Moreover,the heterogeneity test reveals that the policy has a stronger driving effect on the high-quality economic development of cities in the east and west,and also has a positive effect on the high-quality development of neighboring regions.Further research suggests that the policy has positive spatial spillover effects on the high-quality economic development of neighboring cities.
