粮食主产区的利益补偿不仅包括传统的反哺性补偿，还应包括可以提升自我发展能力的内生性利益补偿机制。文章结合安徽省11个粮食主产区（县）283份农户实地调研数据，通过结构方程模型分析安徽省粮食主产区内生性利益补偿机制的影响因素，发现粮食产品再加工、特色农产品品牌培育、鼓励创新机制、农业专业合作社和农产品物流配送对内生性利益补偿机制有着直接的影响效应，粮食补贴、粮食价格、农资价格、粮食产量、农田水利建设和生态环境保护对内生性利益补偿机制有着间接的影响关系。新型农村合作保险、新型农村合作医疗和最低生活保障对内生性利益补偿机制的影响效应不大。

The benefit compensation of main grain producing areas includes not only the traditional feedback compensation, but also the endogenous benefit compensation mechanism which can improve the self-development ability. Based on data of 283 farmers in 11 main grain producing areas(counties) of Anhui province, this paper analyzes the influencing factors of the compensation mechanism of the inherent benefits in the main grain producing areas of Anhui province by structural equation model. It is found that reprocessing of grain products, brand cultivation of characteristic agricultural products, encouraging innovation mechanism, agricultural professional cooperatives and logistics distribution of agricultural products have direct effects on endogenous benefit compensation mechanism, while grain subsidies, grain prices, agricultural prices, grain output, farmland water conservancy construction and ecological environment protection have indirect effects on endogenous benefit compensation mechanism. New rural cooperative insurance, new rural cooperative medical care and minimum living security have little effect on the compensation mechanism of endogenous benefits.
