90年代中国省级区域经济与环境协调度分析

Differentiating and analysis of the coordination degree between economic development and environment of provinces (regions) in China

在阐述经济环境协调度理论的基础上 ,建立了环境承载力与经济发展水平之间的协调度模型。并通过对 90年代我国省级区域的实证分析 ,发现我国空间区域经济环境协调度基本符合“U”型曲线 ,区域经济发展模式大多以牺牲环境为代价 ,特别是中西部地区的问题比较严重。

Based on the theory of economic development and environmental protection, the paper first offers a Coordinated Degree Model (CDM) on the relation between the stage of economic development and the capacity of environment. The authors expound the notion of coordination degree and believe that there exists the best harmonizing range at different economic development periods. The optimization of economic & environmental system does not mean optimization of all parts , the whole optimizations based on both harmony are more important. Environment carrying capacity is the most important factor which will affect optimization.It also makes differentiating classes for provinces (regionsf) according to economic & environment coordination degree, regardingeconomic development and resources & environment as a unified entity, it is fit for sustainable development thought. The result of the demonstrative analysis on the provinces (regions) in China by using the CDM revealed that the relation of the economic development and the environment is in line with the 'U shaped' curve. The 'U shaped' curve demonstrated that the pattern of the economic development in China was not ideal, which is brought by the decrease of the capacity of the environment. The most serious area is middle west China. This conclusion will help forecast turning period in differents regions, so people can adjust it on time, avoid uncover effect of economic development on resources & environment.
