粮食主产区政策实施对涉农企业经营效益的影响

The Impact of Major Grain Producing Area Policy Implementation on the Business Profits of Agricultural Enterprises

本文基于浙大卡特一企研中国涉农研究数据库(CCAD)数据,采用断点回归设计,在企业微观层面研究粮食主产区政策实施对涉农企业经营效益的影响。结果表明,粮食主产区政策实施提升了其范围内涉农企业的营业净利润率。机理分析发现,粮食主产区政策实施不仅有助于提高涉农企业全要素生产率,实现要素投入结构优化,获取成本优势,而且能够通过鼓励涉农企业参与多种形式的产业融合,拓宽收入渠道。进一步分析显示,相对于非粮食企业,粮食企业受粮食主产区政策积极作用的效应更大。本文的研究结论为探索粮食主产区政策实施促进农业生产经营效益增长的作用机制和优化路径提供了经验证据。

Based on the data of China Academy for Rural Development Qiyan Database(CCAD),this paper employs a regression discontinuity design to examine the impact of the major grain producing area policy implementation on the business profits of agricultural enterprises at the micro-level.The results indicate that the implementation of the policy in major grain producing areas enhances the business profit margin of agricultural enterprises.Mechanism analysis reveals that the policy implementation not only facilitates the promotion of technological efficiency in agricultural enterprises to improve TFP,optimize input structure,and gain cost advantages,but also encourages agricultural enterprises to participate in various forms of industry integration,thereby expanding income channels.Further analysis shows that,compared with non-grain enterprises,grain enterprises experience a greater positive effect from the policy.The conclusions of this study provide empirical evidence for exploring the mechanisms and optimization paths through which the major grain producing areas promotes the business profit growth of agricultural production.
