Abstract: According to the current situation of policy-based agricultural insurance in Shaanxi Province, this study selected DEA model and Malmquist index method to analyze the factors influencing policy-based agricultural insurance in Shaanxi Province. The results showed that the comprehensive efficiency of policy-based agricultural insurance in both 2018 and 2019 had not reached DEA validity, and the efficiency of policy-based agricultural insurance in different regions varied greatly. There was room for improving technology efficiency and scale efficiency in most regions to varying degrees. From the Malmquist index dynamic analysis, it could be seen that the average value of the total factor productivity index of policy-based agricultural insurance in Shaanxi Province from 2016 to 2019 was 0.851, and the overall efficiency was in the rising stage. The improvement of comprehensive efficiency in most regions was jointly driven by technology efficiency and technology progress, so the changes in technology efficiency and technology progress played a primary role. This paper put forward suggestions for enhancing the efficiency of agricultural insurance in Shaanxi Province.
