长江经济带城镇化的生态环境效应研究

Impact of Urbanization on Ecological Environment in the Yangtze River Economic Belt

基于长江经济带11个省(市)2000-2014年省级面板数据,从直接效应和溢出效应两个维度实证研究了城镇化对长江经济带生态环境的影响效应,结果表明:(1)人口城镇化与土地城镇化均加剧了长江经济带环境污染水平;(2)溢出效应中居民收入增长有利于提升环境质量水平,而经济增长、产业转移会对生态环境造成破坏;(3)考虑溢出效应后,土地城镇化会有利于提升环境质量水平,而人口城镇化对环境的影响不显著。最后提出相关政策建议。

We study the impact of urbanization on the ecological environment from the perspectives of direct effect and spillover effect based on eleven provincial panel data in the Yangtze River Economic Zone from 2000 to 2014. The result indicates ：（ 1） The urbanization of population and the urbanization of land have exacerbated the environmental pollution in the Yangtze River economic zone.（ 2） The growth of residents＇ income is beneficial to the improvement of environmental quality while the economic growth and industrial transfer would damage the ecological environment.（ 3） Urbanization of the Yangtze River economic zone would improve the environmental quality,and the impact of urbanization of population on the environment is not significant.
