农业生产性服务对农业生产效率的影响研究——基于CHFS数据的实证分析

Research on the Impact of Agricultural Productive Services on Agricultural Production Efficiency——Empirical Analysis Based on CHFS Data

农业生产性服务是现代农业生产体系建设的活力源泉,对提高农业生产效率,实现农业强国具有重要意义。基于2015年中国家庭金融调查数据(CHFS),运用固定效应模型、工具变量法等实证分析农业生产性服务对农业生产效率的影响。研究发现:(1)农业生产性服务对农业土地生产率、劳动生产率、全要素生产率具有显著的促进作用,对农业成本利润率具有显著的负向影响。(2)农业生产性服务对不同地区的不同农业生产效率的影响不一样。具体而言,西部地区农业生产性服务对农业生产效率的影响显著高于东、中部地区,东、中部之间的农业生产性服务对农业生产效率的影响差异不大。

Agricultural productive services are the source of vitality for the construction of modern agricultural production systems,and are of great significance for improving agricultural production efficiency and achieving a strong agricultural country.Based on the 2015 China Household Finance Survey(CHFS)data,this paper empirically analyzes the impact of agricultural productive services on agricultural production efficiency by using the fixed effect model and Instrumental variables estimation method.Research has found that(1)agricultural productive services have a significant promoting effect on agricultural land productivity,labor productivity,and total factor productivity,and have a significant negative impact on agricultural cost profit margin.(2)The impact of agricultural productive services on different agricultural production efficiency varies in different regions.The impact of agricultural productive services in the western region on agricultural production efficiency is significantly higher than that in the eastern and central regions.However,there is no significant difference in the impact of agricultural productive services on agricultural production efficiency between the eastern and central regions.
