摘要
地域间环境质量演进存在着明显的区域相关性,而传统的EKC研究中往往忽视这种空间效应,使得研究结果存在偏差。本文基于空间面板模型,结合不同固定效应分析,对中国29个省级区域1990-2006年间工业三废密度与人均GDP之间的作用关系进行了探索研究。实证结果表明,我国经济增长与环境质量作用关系之间存在明显的空间相关性,同时,在纳入空间效应的条件下,除工业废水外,其他环境指标与人均GDP之间皆符合EKC关系。
There＇re distinct spatial relationships among the environmental quality in diffenrent districts. However, conventional EKC studies have not pay much attention to the potential spatial relationships, risking misspecifications and presenting incorrect reasons. Based on spatial panel data along with different kinds of fixed effects, this paper analyzes the relationships between the density of industrial waste and GDP per capita for 29 provinces in China from 1990 to 2006, revealing the obvious spatial relationships in the data, and explaining the EKC＇s existence in two industrial wastes taking the spatial relationships into account.
