摘　　要：针对社会化服务与农业数量产出的关系存在争论的现状,本文利用能值理论,从单项社会化服务接受情况、接受服务的广度和接受服务的深度三个方面,在农业经营主体层面构建了一个可以综合考察社会化服务如何影响农业产量水平的分析框架。通过来自山东、河北、安徽、陕西、吉林5省调研收集的千余个农业经营主体的样本数据分析显示,大多数产前、产中、产后的单项服务并不具有明显的产量促进作用;服务广度对农业经营主体的总产水平和单产水平总体呈现显著的正向作用,但其产量效应在普通农户与新型农业经营主体两类群体中的结果刚好相反;服务深度总体上并不能促进农业经营主体的产量水平,仅对合作经营和企业经营的新型农业经营主体的产量水平有正向作用。此外,农业经营主体对所接受社会化服务的满意度与其农业产量水平呈显著的正相关关系,说明社会化服务的质量是关键。以上结果对厘清社会化服务与经营主体的农业产量水平之间的逻辑关系,揭示社会化服务的功能发挥机制具有重要的政策含义。In view of the debate on the relationship between agricultural socialized services and agricultural quantitative output,this paper uses the emergy theory to build an analytical frame⁃work that can comprehensively examine how agricultural socialized services affect the level of agri⁃cultural output at the level of agricultural entities from three aspects:the acceptance of individual services,the breadth of services and the depth of services.The analysis of the sample data of more than 1000 agricultural entities obtained from the survey in five provinces of Shandong,Hebei,An⁃hui,Shaanxi and Jilin shows that most of the single services before,during and after production do not have a significant role in promoting output.The service breadth has a significant positive effect on the total output and per unit area yield of agricultural entities,and its output effect is just op⁃posite in the two groups of ordinary farmers and new agricultural entities.In general,the depth of service does not promote the output level of agricultural entities,but only has a positive effect on the output level of new agricultural entities of cooperative and enterprise operation.In addition,there is a significant positive correlation between the satisfaction of agricultural entities to agricul⁃tural services and their agricultural output level,indicating that the quality of service is the key.These results have important policy implications for clarifying the logical relationship between agricultural services and the output level of agricultural entities,and revealing the functional mech⁃anism of agricultural services.
