| 摘 要： | 以废水排放总量、废气排放总量以及固体废弃物储存总量表征环境污染的综合水平,研究丽江市经济发展与环境污染水平之间的关系。结果表明:1994~2007年丽江市环境污染状况随经济增长呈现波动变化,环境库兹涅茨曲线大体呈现"倒U形+U形"的变化特征。其中"倒U形"的峰值出现在1998~1999年人均GDP为2000~3000元之间,"U形"的低谷出现在2001~2002年人均GDP为3000~4000元之间。进一步分析工业废水排放量、工业废气排放量、工业固体废物贮存量等单项指标的环境库兹涅茨曲线,分别呈现"U形曲线的下降阶段"、"U形曲线的上升阶段"和"倒U形+U形+倒U形"特征,即M形。分析表明,上述环境库兹涅茨曲线特征,与污染物排放量、产业结构变动、环境保护投资力度、环保政策等有密切的关系。

| Abstract: | Environmental Kuznets Curve (EKC) is a hypothesized relationship between the environmental degradation and economic growth. It is also known that Environmental Kuznets Curve shows classical "inverted U-type" shape. A sizable literature on EKC has grown in the recent period, and the empirical studies of EKC have shown several different relationships between environmental degradation and economic growth in various research regions, such as monotone relationship, U-shaped relationship and N-shaped relationship. This study tested the empirical relationship between the environmental degradation and economic growth, taking Lijiang city as case study. Using the data of waste water discharge, waste gas emission and solid waste storage volume from 1994 to 2007, we found that the tested EKC presented the shape of "inverted U-type+U-type", which is not the classic "inverted U-type" shape. The situation of environmental degradation fluctuated with economic growth. To study further, it is found that the "inverted U-type" peak appearedin 1998-1999 when per capita GDP was between 2000-3000 RMB yuan, while the bottom point appeared in 2001-2002 when per capita GDP was between 3000-4000 RMB yuan. As for the single indicators such as wastewater discharge, waste gas emission and solid waste storage volume to represent environmental degradation EKC shows the shape of the decline phase of the "U-type" curve, the rising phase of the "U-type" curve and "inverted U-type + U-type + inverted U-type" (that is M shape) respectively. In-depth analysis of the reasons of the new shape of EKC indicated that the impact factors include pollutant emissions, industrial reconstructing, environmental protection investment and environmental protection policies, in which the secondary industry is the key factor. We expect that the above results could provide advices to decision-making for the harmonious development between environment and economy of Lijiang city. |
