环境库兹涅茨曲线(EKC)描述了环境污染与经济增长之间存在倒U型关系,然而需求结构与经济增长有很大的关联,进而影响环境质量。本文通过研究中国2001-2012年31个省市需求结构与环境污染之间的关系,得到实证结果:需求结构与环境之间并非单纯的线性关系;消费需求与环境污染之间呈现出U型结构,并且当最终消费占总需求比重达到65.34%时,环境质量最好,政府消费需求的提高对环境的利好程度大于居民消费的提高对环境的利好程度;投资需求与环境污染之间呈现出倒U型关系,当最终投资占总需求比重达到57.9%时环境质量最差;净出口需求与环境质量呈正向关系,贸易顺差有利于我国环境质量的提高。
The Environmental Kuznets Curve( EKC) illustrates an inverted U-shape relationship between pollutant emission and economic development. Because the demand structure is closely correlated with economic growth it will affect the environmental quality. This paper gave the empirical study of the relationship between demand structure and economic development and the results were as follows: The relationship between demand structure and the environmental emission is not simply linear; There exhibits a U-shape relationship between consumption demand and environmental pollution and the quality of environment is the best when consumer demand account for 65. 34% of the aggregate demand. Improving government consumption demand is more beneficial to the environment than improving individual consume demand; The relationship between investment demand and environment emission is much like an inverted Ushape and the quality of environment is the worst when investment demand account for 57. 9% of the aggregate demand.There was a positive relationship between the net export demand and environmental quality and trade surplus is conducive to the improvement of environmental quality.
