摘要
优化耕地产权配置对保障国家粮食安全具有重要意义。基于1385户粮农调查数据,利用SFA与Probit模型,按照耕地产权是否从弱生产能力主体转移给比较优势主体以减少租值耗散的思路,探求全程托管是否优化了耕地细分经营权配置,利用PSM模型探求全程托管对耕地利用率的积极效果。结果表明,全程托管优化了耕地管理权和操作权在农户间的配置,有效解决了由于政策、土地流转市场不健全、农户对土地保有个人偏好等原因,导致的耕地在不同生产能力农户间配置的扭曲和效率损失;在对耕地细分经营权再配置效果影响方面,全程托管不论相对于服务完全内化的经营形式还是接受分散环节外包服务的经营形式,都会优化耕地投入产出,弱生产能力农户将耕地管理权与操作权转出的越彻底,耕地投入产出得到优化的程度越大;全程托管对种植玉米耕地投入产出的优化程度大于对种植大豆耕地投入产出的优化程度。因此,应防止托管组织垒大户,构建“安心机制”降低弱生产能力农户参与托管所遇阻碍,引导大豆托管服务规模扩大和服务技术提升等。
It is of great significance to optimize the allocation of farmland property rights for ensuring grain security.Based on a survey data of 1 385 households and applying the theoretical framework of whether farmland property rights are transferred from farmers with weak production capacity to farmers with comparative advantages to reduce the rent dissipation,this paper explored whether or not the whole agricultural production trusteeship can optimize the allocation of farmland subdivision management rights by the SFA and the Probit models and examined the positive effect of the whole agricultural production trusteeship on the utilization rate of farmland by the PSM model.Results show that,the whole agricultural production trusteeship can optimize the allocation of farmland administration right and operation right among farmers and solve the distortion and efficiency loss of farmland allocation caused by policies,imperfect land transfer market,farmers' personal preferences for land tenure,and other reasons.In terms of the reallocation effect of farmland subdivision management rights,whether compared with the production form of service internalization or the production form of accepting decentralized outsourcing services,the whole agricultural production trusteeship can optimize the input and output of farmland.The more thoroughly the weak productive farmers transfer out farmland administration right and operation right,the greater the degree of optimization of the input and output of farmland.The optimization degree of the whole agricultural production trusteeship on the input and output of corn farmland is greater than that of soybean farmland.Therefore,this paper provides the following suggestions:preventing trusteeship organizations from building large households,building “reassuring mechanism” to reduce the obstacles encountered by farmers with weak production capacity in participating in trusteeship,and guiding the expansion of soybean trusteeship service scale and the improvement of service technology.
