89.Influences of Agricultural Insurance Policies on Farmer Household’s Planting Scale —Taking corn farmer households in Inner Mongolia Autonomous Region for example

Theoretically, agricultural insurance policies can change the probability distribution of a farmer household’s net income, affect his expected return, and make him reallocate resources to improve the utility level, thus exerting influences on his investment of agricultural production factors, such as land, capital and labour force. This paper carries out an empirical research on whether the policy-oriented agricultural insurance in Inner Mongolia Autonomous Region has influences on corn farmer households’ motivation by means of “Logit” model and maximum likelihood estimation. The study shows that farmer households’ planting decisions are closely related with the market risks, agricultural insurance policies, as well as their personal and family characteristics, of which market risks are the primary factors and policy-oriented agricultural insurance is also key factors taking effect, that is, the better an agricultural insurance participating farmer household’s s on the policy-oriented agricultural insurance is, the more likely he willmaintain or expand planting area.
