| 摘 要： | 土地流转背景下提高农业生产社会化服务供给效率,满足农户生产社会化服务需求对于实施乡村振兴战略具有重要意义。本文基于陕甘宁黄土高原区973户农户数据,从基础设施服务、农资供应服务、技术管理服务、加工销售服务、金融保险服务5个方面刻画农业生产社会化服务,并采用倾向得分匹配法（PSM）探讨了土地流转对农户生产社会化服务需求的影响。研究发现：① 土地流转使得农户生产社会化服务需求呈现出明显的异质性,这种总体效应主要由土地转入带来的规模效应贡献;② 土地流转对基础设施服务、技术管理服务、加工销售服务、金融保险服务具有显著的促进作用,农户需求强度分别提高0.215、0.070、0.094和0.162;土地流转对农资供应服务具有显著的抑制作用,抑制强度为0.306;③ 土地转入对农户生产社会化服务需求的影响方向与土地流转影响的总体方向一致,且影响强度大于总体强度;但土地转出与土地流转影响的总体方向差异较大,且影响强度小于总体强度。提出减少政府供给农资供应服务、加强农业技术推广力量、拓充社会化服务内容等政策建议,以此提高农业生产社会化服务供给水平,促进小农户与现代农业有序衔接。

| Abstract: | Under the background of land circulation, improving the supply efficiency of socialized service for agricultural production and satisfying the socialized service needs for farmers' production are of great significance for the implementation of the strategy of revitalizing the country. Based on the data of 973 households in Loess Plateau Area of Shaanxi, Gansu, and Ningxia, the socialized service for agricultural production is described by infrastructure service, agricultural material supply service, technology management service, process and sale service, and financial and insurance service. This study selected the propensity score matching model to investigate the effect of land circulation on socialized service demands. We found that: ① Land circulation makes the socialized service needs for farmers’ production heterogeneity obviously. The overall effect mainly stems from the scale effect of land transfer-in. ② The land circulation has a significant role in promoting infrastructure service, technology management service, process and sale service, and financial and insurance service. Farmers’ demand strengths are increased by 0.215、0.070、0.094, and 0.162, respectively. The land circulation exhibits a significant inhibitory effect on the agricultural material supply service and the inhibitory intensity is 0.306. ③ The influential direction of land transfer-in on the socialized service needs for farmers’ production is consistent with the overall influential direction of land circulation and the impact strength is greater than the overall strength. However, the influential direction of land transfer-out on the social service needs for farmers’ production is greatly different from the overall influential direction of land circulation and the impact strength is less than the overall strength. The government should reduce the agricultural material supply service, strengthen the promotion strength of agricultural technology, and expand the content of socialized service for agricultural production in order to improve supply level of agricultural socialized service and promote orderly convergence between small-scale farmers and modern agriculture. |
