内部管理效率对农业生产效率影响的实证分析

农业生产效率与技术效率紧密相关,技术效率通常受到外部环境效应、内部管理效率以及随机误差这3个因素的影响.为了单独测算内部管理效率这一内生因素对生产效率的具体作用,通过构建3阶段DEA(Data Envelopment Analysis)模型,消除了外部环境效应和随机误差这2个外生因素对技术效率值的影响.又以2008年中国31个省市为例,测算了资源节约型、环境友好型农业生产的综合效率,并依据实证分析的结果,提出了相应的促进资源节约型、环境友好型农业发展的政策建议.

Effect of Internal Management Efficiency on Agricultural Production Efficiency

Resource-saving agriculture and environment-friendly agriculture is a complex organism involving production,economy,society and ecology.Its development process is influenced by various factors,such as producers,nature,society,etc,and so is agricultural production efficiency.In order to overcome the measurement error of traditional data envelopment analysis caused by ignoring random factors,this paper employed the three-stage data envelopment analysis model to remove environmental factors and random effects.On the basis of this model,it estimated the resource-saving agriculture and environment-friendly agriculture comprehensive production efficiency of 31 provinces and cities in China,and brought forth corresponding policy proposals to promote agricultural development.
