中国城镇化对二氧化碳排放的影响效应:基于省级面板数据的经验分析

Effect of Urbanization on CO_2 Emissions in China:Empirical Study Based on Provincial Panel Data

在结合STIRPAT模型和简单环境库兹涅茨曲线基础上,建立城镇化对二氧化碳排放影响的实证模型,利用中国1997—2009年省级面板数据,实证研究城镇化对二氧化碳排放的影响效应。研究结果表明:城镇化与二氧化碳排放存在长期的均衡关系;城镇化对二氧化碳排放影响呈现地区间差异,全国和东部地区两者呈现倒N型关系,与中部地区两者呈现N型关系,与西部地区两者虽呈现倒N型关系,但统计上不显著。

Based on the STIRPAT model and the simple environmental Kuznets curve,this paper constructs the empirical model and analyzes the impact of urbanization on China's CO2 emissions by using provincial panel data in 1997—2009.The main findings are as follows:urbanization and CO2 emissions have a steady equilibrium relationship in the long run;the impact of urbanization on CO2 emissions has obvious regional difference,and the inverse N-shaped relationship is found between urbanization and CO2 emissions in the eastern region,while the N-shaped relationship is found in the central region,and the inverse N-shaped relationship is found in western region,though not statistically significant.
