Research on the Spatial-temporal Differences and Influencing Factors of Anhui Industrial Environmental Efficiency

Abstract

In order to improve the efficiency of industrial environment in Anhui Province and promote the coordinated development of industrial production and environmental protection, industrial waste water discharge, air particulate matter discharge and solid waste discharge are regarded as undesirable outputs. The model measures the industrial environmental efficiency of 16 prefecture-level cities in Anhui Province from 2013 to 2018, and fully considers the differences between regions; then, based on the analysis of the total factor productivity of the industrial environment, the impact of industrial environmental efficiency in each province is found factor. Finally, through the construction of the Malmquist index model, the spatial-temporal change trend of industrial environmental efficiency in Anhui Province was analyzed. Studies have shown that there is a clear difference in the efficiency of the industrial environment in Anhui Province. The change trend of TFP and TEC is basically the same. TEC is the main influencing factor of TFP. All regions should pay attention to technological innovation, adjust the existing industrial production model, coordinate the relationship between industrial development and resource environmental protection, and gradually improve their own industrial environmental efficiency.
