农业前沿技术进步、技术效率和农民增收

Agricultural frontier technology progress,technical efficiency and farmers' income increasement

农业技术进步可分解为前沿技术进步和技术效率,不同技术来源的选择可能对农民增收产生异质性影响。本文将农业前沿技术进步、技术效率与农民增收纳入统一分析框架,运用省级面板数据,采用克服内生性问题的计量模型展开分析。研究表明,农业前沿技术进步和技术效率对农民增收具有显著的积极作用,农业技术效率对农民增收的积极作用明显大于前沿技术进步;前沿技术进步和技术效率对农民增收效应存在区域异质性,东中部省份的农业前沿技术进步和技术效率对农民增收的影响均具有显著的促进作用,而西部地区农业前沿技术进步对农民增收的影响不显著,技术效率对农民增收的影响显著为正。本文的研究为优化财政支农支出结构、实施科技富农战略提供了方向。

Agricultural technological progress can be decomposed into frontier technological progress and technological efficiency.The choice of different technological sources may have a heterogeneous impact on farmers’ income.With Chinese provincial panel data,the model of overcoming endogeneity is adopted,the paper brings the agricultural frontier technology progress,technical efficiency and farmer income increasement into the unified analysis frame.The empirical research shows that,the improvements of agricultural frontier technology progress and technical efficiency have a significant positive effect on farmers’ income,and the marginal effect of the latter is greater than that of the former.The effects of frontier technology progress and technical efficiency on farmers’ income have regional heterogeneity.Both the agricultural frontier technology progress and technical efficiency have a significant positive effect on farmers’ income in the East and Central China,however,the effect of agricultural frontier technology progress on farmers’ income is not significant in the West China.Our research provided direction on how to use agricultural science and technology to increase farmers’ income.
