摘要：With the development of technology, the negative effects brought about by innovation have become more and more attractive. But there are few studies on the relative efficiency of input and output in a region. Since the input and output of a region are multidimensional variables. Therefore, this paper adopts the DEA method, first analyzes 16 cities in Anhui Province without environmental pollution index, and finds that Hefei is in an inefficient region with decreasing scale. Under the same input, it is necessary to improve the efficiency of technology input. After introducing the environmental index, Hefei has reached the effective input standard, and four cities have not reached the effective decision-making unit. Among them, Maanshan, Xuancheng and Anqing are in the stage of increasing returns to scale. For these three regions, technology investment can be increased. . Based on the results of the above data analysis, the corresponding measures are proposed and the direction of policy designation is indicated.
