摘要
不断提升农业全要素生产率是保障中国粮食安全的关键,而农业机械化作为农业现代化的基本内涵与技术支撑,是提升农业全要素生产率的重要途径。本文以种植业为例,采用Malmquist生产率指数的方法测算中国31个省份种植业全要素生产率,并通过OLS方法对农业机械化水平对种植业全要素生产率的影响路径和特点进行实证分析。研究发现,农业机械化水平对种植业全要素生产率的提升具有显著促进作用,且在农业机械化发展不同阶段其提升的路径和特点不同,在初级阶段农业机械化水平通过技术进步路径提升种植业全要素生产率的作用最大,而在中、高级阶段农业机械化水平通过技术效率变化路径提升种植业全要素生产率的效应更大。本文准确分析判断农业机械化水平对种植业全要素生产率提升的作用机制和影响特点,为各地区更好地发挥农业机械化在提升农业全要素生产率方面的作用而采取不同的政策措施提供理论依据。
Improving the total factor productivity of agriculture continuously is the key to ensuring China’s food security.As the basic connotation and technical support of agricultural modernization,agricultural mechanization is an important way to improve the total factor productivity of agriculture.This article takes the farming industry as an example,Malmquist Productivity Index is used to measure and decompose crop productivity in various regions of China,and the impact characteristics and impact path of agricultural mechanization level on total factor productivity of crop production are carried out by OLS method.The research finding:The level of agricultural mechanization has significantly promoted the improvement of total factor productivity in the crop industry,the path and characteristics of upgrading were in different stages of agricultural mechanization development.In the primary stage,the improvement of agricultural mechanization level through technological progress path has the greatest effect on total factor productivity of the planting industry,while in the middle and advanced stage,the improvement of agricultural mechanization level through technological efficiency change path has a greater effect on total factor productivity of planting industry.The accurate analysis and judgment of the mechanism and characteristics of the effect of agricultural mechanization level on the improvement of total factor productivity of the planting industry can provide a theoretical basis for different policies and measures to better play the role of agricultural mechanization in the improvement of total factor productivity.
