摘要
基于环境库兹涅兹曲线(EKC)假说,利用面板单位根和面板协整方法研究中国省区1985-2004年间废气、废水和固体废弃物3种污染物排放量与收入之间的关系.面板检验显示,变量之间存在长期EKC关系,协整估计结果表明,废气和固体废弃物排放量随收入增加呈先上升后下降的趋势,而废水则表现为单调递增关系,且其转变点尚未出现.随治理技术进步,废水排放量呈现单调递减的趋势,而废气和固体废弃物呈现先上升、后减少、再上升的波动过程.
Based on the environmental Kuznets curve(EKC) hypothesis, utilizing panel unit root and panel cointegration methods, the relationship between three kinds of pollutants emission (waste gas, wastewater and solid wastes) and income of the Chinese provincial areas in the period 1985-2004was studied. The long-run EKC relationship existed between change amounts. With the increase of income, waste gas and solid wastes tended to increase first and then decline, but wastewater emission appeared a monotonously increasing relationship with its turning point not appeared yet. With the technical progress, wastewater emission tended monotonously to decline, while waste gas and solid wastes emission appeared increasing first, then decreasing and again increasing waving process.
