Abstract: Since the reform and opening up, the development of agricultural insurance in China has experienced four stages: restoration, stagnation and shrinkage, exploration and expansion, and quality improvement. At present, the academic research on the evolution of agricultural insurance policy is mostly focused on the macro level of qualitative research, lack of quantitative and qualitative comprehensive analysis of empirical research. From the perspective of policy evolution, this paper combs the policy documents on agricultural insurance from 1982 to 2021. Based on text analysis, this paper uses GooSeeker and co-word analysis to mine the text of 785 local policy documents and uses Gephi to realize the visualization of mining results. The results show that the inherent logic of the evolution of agricultural insurance policy in China is as follows: the mode of policy change changes from government compulsion to pluralistic coordination; the policy orientation gradually shows the characteristics of strong response; the policy tools gradually change from singleness to diversification; policy orientation changes from expending coverage to high-quality development. Based on the critical period of structural adjustment, transformation and upgrading and the reconstruction of governance system in agricultural and rural areas, this paper puts forward the following policy suggestions: strengthen the synergy between government and market, improve the systematic top-level design of agricultural insurance, and speed up the pace of policy innovation and cooperation.

Key words: agricultural insurance, policy evolution, internal logic
