农业社会化服务体系是衔接我国小农户与现代农业的有效途径，2017-2020年中央一号文件均提出通过将农业生产外包、托管服务等形式带动农业规模经营。 发展玉米生产社会化服务是促使吉林省农业生产方式升级的重要途径，也是促进农业生产经营规模化的重要手段，同时提升黑土耕地质量。本文采取二元Logistic选择模型，通过对吉林省玉米种植户购买生产社会化服务的意愿与行为相悖离的影响因素进行分析，发现社会化服务认同感、土地总面积、土地细碎化程度和社会化服务宣传四个因素最为显著，其次是社会化服务了解程度和土地流转面积，受教育程度、家庭年收入和社会化服务主体数量等因素也具有一定的影响。并据此提出政策启示，以期为促进玉米种植户采纳社会化服务提供参考借鉴。

The agricultural socialization service system is an effective way to link up the small farmers and modern agriculture in China. In the 2017-2020 year, the No. 1 central document proposed that the agricultural scale operation should be promoted by outsourcing agricultural production and hosting services. The development of corn production socialization service is an important way to promote the upgrading of agricultural production mode in Jilin Province, and also an important means to promote the scale of agricultural production and management, and improve the quality of black soil cultivated land. In this paper, binary logistic model is used to analyze the influencing factors of the contradiction between willingness and behavior of corn growers in Jilin Province. It is found that the four factors of social service identity, total land area, degree of land fragmentation and social service publicity is the most significant, followed by the degree of understanding of social service and land circulation area Education level, annual family income and the number of social service subjects also have a certain impact. Based on this, the paper puts forward policy implications, in order to provide reference for promoting corn growers to adopt social services.
