财政支农补贴能有效提升粮食全要素生产率吗?——兼顾农业技术环境的调节作用探讨

为了解中国财政支农补贴与粮食全要素生产率之间的影响关系,采用传统DEA-Malmquist指数法测算粮食全要素生产率,以结构效应和技术效应为中介,以农业技术环境为调节,探究财政支农补贴对粮食全要素生产率的影响机制。结果表明:财政支农补贴能够有效促进粮食全要素生产率的提升,并且对非粮食主产区粮食全要素生产率的影响要大于粮食主产区;财政支农补贴通过发挥结构效应和技术效应,提高粮食全要素生产率;在较优的农业技术环境中,财政支农补贴对粮食全要素生产率具有较强的促进作用。据此,从完善财政支农补贴政策,充分发挥结构和技术效应,加大农业技术环境优化力度3个方面提出促进粮食全要素生产率增长的政策建议。

Will financial subsidies for agriculture effectively increase the total factor productivity of food: The moderate effect of agricultural technology environment

In order to study the relationship between China''s financial subsidies for agriculture and grain total factor productivity, this study adopts the traditional DEA-Malmquist index to measure grain total factor productivity, takes structural effects and technological effects as mediation, and uses agricultural technology environment as moderation to explore the influence mechanism of financial subsidies for agriculture on grain total factor productivity. The results show that: The financial subsidies for agriculture can effectively increase the TFP, and the impact on non-major food producing areas is greater than that of major food producing areas. The financial subsidies for agriculture increase the TFP through structural and technological effects. In a better agricultural technology environment, the financial subsidies for agriculture have a significant role in promoting the TFP. In the end, this study puts forward suggestions to promote the TFP, such as improving fiscal subsidy policies for agriculture, making full use of structure and technical effects, and increaseing the optimization of the agricultural technology environment.
