Regional Innovation System Efficiency Assessment in Sichuan Based on DEA Model and Coupling Theory

摘要

The efficiency of the regional innovation system affects the benefits of regional innovation development, and scholars are paying more and more attention to research in this area. However, there has been no consensus on how to reasonably evaluate the efficiency of regional innovation systems. This paper first builds an input-output indicator system, then measures the efficiency of the regional innovation system based on the SBM model, and establishes a coordination model based on the coupling theory to analyze the coordination level of the regional innovation system. Finally, a data set of the regional innovation system in Sichuan Province for the period 2003-2016 is utilized for empirical estimations. The research results show that the average efficiency of the scientific research institution subsystem (SS), enterprise subsystem (ES), and university subsystem (US) is 0.894, 0.902, and 0.797, respectively. There is a certain difference in innovation efficiency among the three. In terms of coordination, the coordination of the innovation system in Sichuan is relatively good, with a high degree of coordination above 0.922.
