摘要
本文基于新发展理念和经济稳定性,构建城市经济高质量发展的评价指标体系,利用2003—2019年中国278个城市的面板数据,运用多时期双重差分固定效应模型,实证研究低碳城市试点政策对城市经济高质量发展的效应以及内在影响机制。研究结果表明:低碳城市试点政策能够推动城市经济的高质量发展,并通过了一系列稳健性检验;从异质性分析结果来看,低碳城市试点在东部和中部城市的政策效应显著为正,在西部地区政策效应不显著;从中介效应检验机制来看,低碳城市试点政策通过优化投资结构和集聚科技人才,促进了城市经济高质量发展。
According to the concept of new development and economic stability,this paper aims to empirically study the effects of low-carbon city pilot policies on high-quality urban economic development and its intrinsic influence mechanism drawing on the panel data of 278 cities from 2003 to 2019,with the help of a multi-period double difference fixed effect model.The results suggest that the pilot policy can bolster the high-quality development of urban economy,and has passed a series of robustness tests.According to the heterogeneity analysis,the policy effect exerts a significant positive effect on eastern and central cities,but not on western regions;In terms of the intermediary effect mechanism,the pilot policy has promoted urban economy by optimizing investment structure and gathering scientific and technological talents.
