| Agriculture is the "ballast stone" to ensure the stable development of national economy.Clarify the internal relationship between agricultural insurance and agricultural service ecosystem and agricultural output is of great significance to guiding agricultural insurance and agricultural service ecosystem to better serve agriculture and promote high-quality development of agriculture.Under the theoretical guidance of value co-creation,synergistic effect and Pareto improvement,this thesis takes Guangdong Province as an example,based on the panel data of 2012-2020,and the coupled coordination model is used to calculate the coupled coordination degree of agricultural insurance and agricultural service ecosystem,and demonstrates that the coordinated development of the two can improve the level of agricultural output.The empirical results show that,in terms of timing structure,the coupling and coordinated development of the two subsystems at the provincial level experiences the stage of moderate coupling coordination,showing a positive trend;the regional level forms the pattern of West Guangdong> Pearl River Delta and East Guangdong.On the basis of coupling coordination measurement,through the benchmark regression,robustness test and heterogeneity test,the coupling coordination of two subsystems of agricultural output at 5% level has significant positive influence and heterogeneity,performance in coupling coordination can significantly improve high food crops sown area group,the third industry than restructuring and high fixed investment group of agricultural output level.Based on this,in order to maximize the economic effect of the coupled coordination of agricultural insurance and agricultural service ecosystem on agricultural development,the function of "guarantee + service" of agricultural insurance should be optimized to attract high-quality agricultural resources;identify the short board of agricultural service ecosystem development and improve the comprehensive development index;and systematically construct the coordinated development pattern of agricultural insurance and agricultural service ecosystem according to local conditions. |
