Potato is the fourth largest staple food in China,which has a great impact on national food security and dietary nutrition of residents.It has also made important contributions to China’s grain production growth and rural economic development in the central and western regions.In 2015,the former Ministry of Agriculture put the potato stapled grain strategy on the important work agenda,and the development of the potato stapled grain strategy was inseparable from the support of agricultural insurance.Gansu Province is an important commercial potato and ideal seed potato production area in China.The comparative advantage of potato production is significant,and the potato yield and price are negatively correlated.At the same time,the potato industry is also an important agricultural characteristic industry in Gansu,which plays an important role in promoting rural economic development,agricultural efficiency and farmers’ income.However,at present,potato insurance in Gansu is mainly based on production insurance,which only guarantees the loss of agricultural product output,does not guarantee the loss of income caused by price fluctuations to farmers,and the level of protection is low,which cannot meet the risk protection needs of farmers.Based on this,this paper proposes that Gansu Province should develop potato income insurance to protect the natural risks and protect the income loss of farmers due to price fluctuations.Based on the analysis of the necessity and feasibility of the current potato income insurance in Gansu,combined with the experience of the US crop income insurance,the overall design of the income insurance for potato in Gansu was completed,and adopt the potato yield and price data of Gansu Province from 2000 to 2016,the rate of potato income insurance was determined by Copula function and Monte Carlo simulation.Finally,it is recommended to promote the development of potato income insurance in Gansu by improving laws and regulations,strengthening insurance supervision,improving income insurance subsidy policies,establishing a distribution mechanism for agricultural disasters,and strengthening the accumulation of production price data.The relevant analysis,system construction,pricing methods and countermeasures of this paper can enrich the theoretical research of potato income insurance to a certain extent,and provide a reference for Gansu and other areas in China to carry out potato income insurance. |
