乡村产业振兴政策实施前后我国粮食生产效率波动研究

Research on the Fluctuation of Grain Production Efficiency in China Before and After the Implementation of Rural Industry Revitalization Policy

粮食问题事关国运民生,粮食安全是国家安全的重要基础,提高粮食综合生产能力,保障粮食安全是乡村产业振兴的首要任务。乡村产业振兴实施以来粮食生产的效率水平怎样,如何在乡村产业振兴政策下提升粮食综合生产和供给能力是重要的研究课题。基于此背景,利用全国农产品成本收益资料,运用DEA-Malmquist方法对粮食生产效率进行测算。研究发现,乡村产业振兴政策实施前后粮食的生产效率有一定的波动,乡村产业振兴政策实施前,由于新农村建设政策的强力推进,粮食生产效率基本处于上升趋势,但是新农村建设后期,粮食生产效率有下降趋势。乡村产业振兴政策实施以来,粮食的全要素生产率得到了很大提升。为了保证粮食安全,还需要继续稳固和提升粮食生产效率,要以粮食生产者为本,从激励制度、粮食产业分工、资源优化配置三个层面发力,形成协同效应激发粮食生产者的积极性,稳定粮食生产的同时继续提升粮食生产效率,充分实现国家粮食安全。

The food issue bears on the well-being of the country and the people,and food security is an important foundation of national security.Improving the comprehensive grain production capacity and ensuring food security are the primary tasks of the rural revitalization strategy.What is the efficiency level of grain production since the implementation of the rural industry revitalization policy?How to improve the comprehensive production and supply capacity of grain under the rural industry revitalization policy is an important research topic.Based on this background,this paper uses the cost-benefit data of national agricultural products and uses DEA-Malmquist method to measure the efficiency of grain production.The study found that before and after the implementation of the rural industry revitalization policy,the grain production efficiency fluctuated to a certain extent.Before the implementation of tthe rural industry revitalization policy,the grain production efficiency was basically on an upward trend due to the strong promotion of the new rural construction policy,however,in the late period of new rural construction,the grain production efficiency has a downward trend.Since the implementation of the rural industry revitalization policy,the efficiency of grain production has been gradually improved,The total factor productivity of grain has been improved.it is also necessary to continue to stabilize and improve the efficiency of food production.Therefore,the implementation of the rural industry revitalization policy should be based on grain producers,and efforts should be made from the three levels of system,division of labor,and resources to form a synergistic effect to stimulate the enthusiasm of grain producers and at the same time continue to increase the efficiency of food production,achieve full national food security.
