Agricultural Insurance and Food Security:A Quasi-natural Experiment Based on the Pilot Policy of Agricultural Catastrophe Insurance
This study takes the pilot of agricultural catastrophe insurance as a quasi-natural experiment.Firstly,we conduct theoretical analysis based on characteristic facts and propose several theoretical hypotheses:the agricultural catastrophe insurance pilot significantly increases grain production,and there is regional heterogeneity.Secondly,based on the county panel data of Shandong Province from 2013 to 2019,we use the time-varying difference-in-differences method to analyze the impact of pilot on grain yield.Thirdly,we identify and verify the mediating and mod-erating effects of the pilot policies.The study finds that the degree of agricultural scale operation plays a mediating effect,and the initiative of buying insurance plays a moderating effect.So we should continue to improve the level of insurance protection for food crops and accelerate the transformation of agricultural insurance to income insurance.At the same time,it is necessary to continue to improve the level of large-scale agricultural operation,cultivate farmers'awareness of insurance,and give play to the positive role of agricultural insurance in ensuring food security.
