Part of the Research on the Ecological Efficiency Evaluation and Sensitivity Analysis

Abstract

With the rapid development of economy in our country, the environmental pollution problem has got more and more attention of public. To pay attention to the ecological efficiency and to go the way of sustainable development become the consensus of people from all walks of life. This article selects emissions of industrial waste water, emissions of industrial waste gas and industrial solid waste as input index of the environmental pollution, and selects energy consumption per unit GDP and employment as the investment of resource consumption index. Then the article selects regional GDP as output indicators and use data envelopment analysis (DEA) to measure the ecological efficiency of 12 provinces in western China. Then it combines with clustering analysis method to the classification of 12 provinces. Finally it obtains the ecological efficiency factor of the analysis of the western region by sensitivity analysis method of the elements in the input
