Study on Regional Innovation Efficiency Based on DEA Three-stage Model-Take Ten cities in Shaanxi Province as an Example

摘要

In order to further optimize the allocation of innovative resources, improve innovation efficiency, and fully tap regional development potential, this paper uses DEA's three-phase model to evaluate the innovation efficiency of ten cities in Shaanxi Province from the perspective of input and output, and on the other hand, it analyzes the changing trends and differences in time and regional innovation efficiency. The research results show that comprehensive technical efficiency is greatly affected by the scale effect, and the scaled efficiency is often underestimated in more developed cities such as Xi' an. Overvalued cities are relatively underdeveloped, such as Ankang and Tongchuan. The influence of environmental factors is greater.
