我国苹果主产区效率特征及其影响因素分析

On Apples' Productive Efficiency and Influencing Factors in Major Production Areas of China

运用DEA-Tobit两阶段模型对我国8个苹果主产区(省)在2006—2009年期间的生产效率及其影响因素进行了分析,并运用基于非参数DEA的Malmquist生产率指数,对样本期间内苹果主产区的效率变化进行动态评价。实证分析结果显示:在整个研究期间内,由于纯技术效率下降了3.6%,规模效率下降了0.7%,导致全国苹果生产效率出现了负增长;财政支出中农户投资占总投资额的比重、农村居民受教育水平与苹果生产效率呈显著的正相关,而农村居民家庭人均收入与苹果生产效率存在显著的不相关。

This paper analyzed the production efficiency and its influencing factors in 8 major apple production provinces between 2006 and 2009 with DEA-Tobit two-stage model.More importantly,it used non-parametric DEA Malmquist productivity index to evaluate the efficiency dynamically in major apple production areas during the sample period.The case study shows that apple production efficiency declined because the pure technical efficiency and scale efficiency fell 3.6% and 0.7% respectively during the whole study period.Apple production efficiency is positively related with the proportion of peasant household investment to total investment in fiscal expenditure and the education level of rural residents while it is irrelevant with per capita income in rural households.
