长江经济带农业全要素生产率研究

Study on Agricultural Total Factor Productivity in the Yangtze River Economic Belt

基于长江经济带2009—2019年农业生产面板数据,运用Malmquist指数模型对该经济带农业全要素生产率进行测算并分析。结果表明:2009—2019年长江经济带Trpch指数大于1,说明这期间长江经济带农业生产效率总体呈上升态势,但仍然存在着技术进步受阻、缺乏创新型农业科技人才等问题。从地区来看,长江经济带各省(市)的全要素生产率均在上升,但技术水平均未超过1,说明该经济带各省(市)均存在农业进步受阻的现象;在11个省(市)中规模效率均大于1,说明该经济带各省(市)投入规模较为合理。

Based on the panel data of agricultural production in the Yangtze River Economic Belt from 2009 to 2019,this paper uses Malmquist index model to calculate and analyze the agricultural total factor productivity of the economic belt.The results show that the Trpch index of the Yangtze River Economic Belt is greater than 1 from 2009 to 2019,indicating that the agricultural production efficiency of the Yangtze River Economic Belt is generally rising during this period,but there are still some problems,such as the obstruction of technological progress and the lack of innovative agricultural scientific and technological talents.From a regional perspective,the total factor productivity of all provinces(cities)in the Yangtze River Economic Belt is rising,but the technical level is not more than 1,indicating that the agricultural progress of all provinces(cities)in the economic belt is blocked;Among the 11 provinces(cities),the scale efficiency is greater than 1,indicating that the investment scale of the provinces(cities)in the economic belt is more reasonable.
