以四川省、湖南省、河南省、山东省4省问卷调查为基础,从市场风险、管理风险、环境风险和要素风险4个方面构建大田生产服务提供风险评价指标体系,采用模糊综合评价法,对样本区大田生产服务提供风险进行评价.结果显示:南方的四川省、湖南省风险指数分别为3.227和3.197,提供主体面临着较高风险;北方的河南省、山东省风险指数分别为2.895和2.789,提供主体面临的风险水平也相对较低.在4种风险类型中,大田生产服务提供面临的最主要风险是要素风险,其次是环境风险和市场风险,影响最小的是管理风险.最后,从微观和宏观两个层面提出大田生产服务提供风险化解的对策.
Based on the questionnaire survey of 4 provinces in Sichuan Province, Hunan Province, Henan Province and Shandong Province, this paper constructs a risk assessment index system for the provision of production services in large fields from four aspects: market risk, management risk, environmental risk and element risk. By using fuzzy comprehensive evaluation method, The results showed that the risk indexes of Sichuan Province and Hunan Province in the south were 3.227 and 3.197 respectively, providing the subjects with higher risks; the risk indexes of Henan Province and Shandong Province in the north were 2.895 and 2.789, the level of risk faced by the provider is also relatively low. Among the four types of risk, the most important risk faced by the supply of field service is factor risk, followed by environmental risk and market risk, and the least impact is management risk.Finally, From the micro and macro levels, it puts forward the countermeasures to provide risks to the field production service.
