Analysis of Wholesale Industry efficiency in Liaoning Province -- Based on DEA model

Abstract

Based on DEA model, the wholesale efficiency of 14 cities in Liaoning province was measured. From the perspective of input and output, the wholesale efficiency of each city in Liaoning Province was systematically studied to evaluate the development of the wholesale industry in Liaoning Province. The results show that the wholesale efficiency in Liaoning province is generally low, but the returns to scale are increasing. The efficiency level varies greatly among different cities, and the reasons for non-DEA effective wholesale investment in different cities are different.
