最终需求对中国工业行业环境效率的影响分析

Final Demand Impact on China's Industrial Eco-efficiency Analysis

以投入产出法作为基础性方法测算的行业完全环境效率值均低于直接环境效率值;为了从需求角度探索改善环境效率的途径,本文测算了最终需求引致的环境影响量和边际环境效率。在最终需求各分项(国内消费、资本形成和出口)引致的环境影响量中,出口是引致SO2排放的主要因素;最终需求变动引致的边际环境效率较低的行业与最终需求引致的SO2完全排放量较高的行业具有较高的重合性,并且该行业的中间需求率也较高。

Based on the input-output method,the complete environmental efficiency was measured and analyzed. In order to seek the way to improve industry environmental efficiency from the demand point,sulfur dioxide emissions were calculated and analyzed which caused by final demand and the elements of final demand such as domestic consumption,investment and export from the demand point,and marginal environmental efficiency were measured and analyzed which caused by a unit of final demand changes. It is demonstrated that the export is the main factor leading to completely emissions of sulfur dioxide; industries with lower marginal environmental efficiency caused by the change of final demand,and higher completely emission of sulfur dioxide caused by final demand have high coincidence.
