【摘要】 农村第二轮土地承包30年期限已经陆续到期。基于Y省J区D村新一轮土地延包30年试点工作中形成的以调利不调地为核心要义的资源配置方式，深入探究农村第二轮土地承包到期后再延长30年试点工作中效率与公平的关系。结果表明，以调利不调地为核心要义的资源配置方式，一方面通过借助社会大规模参与脱贫攻坚以及乡村振兴战略的制度遗产，满足了极少数无地少地农户的利益需求，在集体层面上保障了全体集体经济组织成员的公平公正；另一方面，对绝大多数农户采取顺延承包的土地延包方式，不断放活农地经营权的自由流转，推动了新一轮土地延包30年试点工作高效开展，进而实现了效率与公平的有机统一。同时，构建开展新一轮土地延包30年试点工作的分析框架，进一步拓展了社会分配理论的应用场景。更多还原

【Abstract】 The 30-year term of the second round of farmland contracting has been expiring one after another. Based on the resource allocation mode with the core principle of adjusting benefits without adjusting farmland formed in the new round of 30-year pilot work of farmland contract extension in D village, J District, Y Province, this paper explores the relationship between efficiency and fairness in the pilot work of 30-year contract extension after the expiration of the second round of farmland contract. The research results show that the resource allocation mode with the core principle of adjusting benefits without adjusting farmland, on the one hand,meets the interests of a very small number of landless rural households through the institutional heritage of large-scale social participation in poverty alleviation and rural revitalization strategy,and ensures the fairness and justice for all members of the collective economic organization at the collective level.On the other hand, the vast majority of rural households have adopted the way of extending the contract of farmland, continuously activating the free circulation of farmland management rights, promoting the efficient implementation of a new round of 30-year pilot work of farmland contract extension, and thus realizing the organic unity of efficiency and fairness. At the same time, the analytical framework for a new round of farmland contract extension pilot work for 30years constructed in this paper further expands the application scenario of social distribution theory.更多还原
