Research on the Calculation and Verification of Income Insurance Rates for Special Agricultural Products——Base on the design and calculation of Hainan natural rubber income insurance
Income insurance can spread the yield and price risks that farmers encounter during the production process ef-fectively and stabilize their expected income.Special agricultural product income insurance has obvious regional characteristics,and reasonable pricing is the key to promoting it.Taking Hainan natural rubber as an example,this paper studies the calculation and verification of the premium rates for local advantageous special agricultural product income insurance.Firstly,the marginal distribution of natural rubber yield and price are fitted by non-parametric kernel density estimation method.Secondly,the Copula function and Monte Carlo algorithm are used to calculate the premium rates of natural rubber income insurance.Final-ly,according to the utility theory,the utility model of farmers is established to test the rate of natural rubber income insurance.The results show that there is a positive correlation between the yield and price of Hainan natural rubber.At the guarantee lev-els of 80%to 100%,the gross premium rates of income insurance range from 4.1%to 13.85%.At the guarantee level of 80%,when the premium subsidy rates are 0%,20%,40%,and 60%,the highest acceptable rates for rubber farmers are 5.09%,6.37%,8.49%,and 12.74%respectively.The premium rates for Hainan natural rubber income insurance are within a reasonable range,and it has the conditions for piloting income insurance.Based on the findings of the study,policy recommendations such as es-tablishing an information management system for special agricultural products,exploring differentiated premium subsidy systems,and continuing to promote pilot income insurance are proposed.
