耕地粮食生产效率测算及影响因素分析——以华北平原河南区域为例

Estimation of Farmland Grain Production Efficiency and Analysis of Influencing Factors--Taking He'nan Area of North China Plain as an Example

以华北平原河南区域为研究对象,基于2000年、2005年、2010年、2015年四期统计数据,使用随机前沿生产函数测算其耕地粮食生产效率,从时间和空间的角度分析华北平原在河南境内耕地粮食生产效率的分布情况。得出以下结论:地区以整体的角度来看耕地粮食生产效率总体比较高,处于平稳上升的趋势。经济比较发达的地区往往耕地粮食生产效率比较低,地势平坦的多平原地区耕地粮食生产效率一般比较高。能够显著影响耕地粮食生产效率的因素有以下4种:化肥施用折纯量、农民人均纯收入、常住人口、粮食播种面积等。

This paper takes the He′nan area of the North China Plain as the research object.Based on the statistical data of four periods in 2000,2005,2010,and 2015,the stochastic frontier production function is used to measure the grain production efficiency of its cultivated land.The He′nan area of North China Plain is analyzed from the perspective of time and space on the distribution of grain production efficiency.The following conclusions are drawn:From a holistic perspective,the efficiency of grain production in cultivated land is relatively high,and it is in a steady upward trend.Food production efficiency in arable land is relatively low in economically developed areas,and food production efficiency in arable land in flat plains is generally high.There are four factors that can significantly affect the grain production efficiency of cultivated land:pure fertilizer application,net per capita net income of farmers,permanent population,and grain sowing areas.
