在理论分析的基础上，利用安徽、山东两省粮食主产区425个规模农户的微观数据，使用OLS回归和倾向得分匹配法实证检验组织介入流转的地块整合效应。研究结果显示，组织介入流转具有显著的地块整合效应，在反事实框架下，组织介入流转使得规模农户的地块平均规模扩大36.01亩，扩大幅度为72.60%。不过，组织介入流转的地块整合效应也存在一定异质性，组织介入流转只有在匹配社会资本匮乏和流转规模适度的农户时，才能发挥其应有作用。因此，要充分认识制度安排对农村土地资源重新配置的影响，既要坚持以市场化配置资源为主线，防范政府部门过度干预，也需要激发村民自治活力，强化服务组织建设，建立规范化、有针对性的土地流转服务体系。

Based on theoretical analysis and by using the micro data of 425 large-scale farmers in the major grain-producing regions of Anhui and Shandong provinces, the land plot consolidation effect of organization intervention in land transfer has been empirically studied by adopting OLS regression model and propensity score matching method. The research shows that organization intervention in land transfer has a significant effect on land plot consolidation. In the counterfactual framework, the average land plot size of large-scale farmers increases by 36.01 mu (with an increase rate of 72.60%) due to organization intervention. However, there is also some heterogeneity in the land plot consolidation effect of organization intervention in land transfer, which can only be applied when it is matched to farmers with lack of social capital and moderate scale of transfer. Therefore, the influence of system arrangement on the reconfiguration of rural land resources should be fully understood. It is necessary not only to adhere to the main line of market-oriented allocation of rural land resources and prevent excessive government intervention, but also to stimulate the vitality of villagers’ autonomy, strengthen the service organization construction and establish a standardized and targeted land transfer service system.
