Evaluation of Economic Efficiency in Western Regions from a New Perspective ——Empirical Research Based on the Three-stage DEA Model

Abstract

This paper uses the three-stage DEA analysis method proposed by Fried et al. (2002) to correct the influence of factors such as environmental variables and random disturbances, and conducts an empirical analysis on the economic efficiency of 31 provincial-level regions in my country from 2010 to 2016. By comparing the economic efficiency of the western region with the central and eastern regions, it focuses on the economic development efficiency of the western region under the new perspective. The study found that the overall level of economic efficiency in China is relatively low, the economic efficiency of the eastern part remains leading and stable, and the efficiency of the central and western regions is relatively low and fluctuates greatly. The overall efficiency of the provincial economy in the western region is relatively low, and the overall efficiency of my country's economic development is gradually converging. We should focus on the characteristics of current economic development and increase investment in the economic development of the western region while maintaining stable economic growth in the eastern and central regions, so as to solve the problem of unbalanced regional economic development in our country.
