中国蔬菜产业生产技术效率及其提高途径分析

Studies on Technical Efficiency of Vegetable Industry Production and Its Improving Approaches in China

技术效率的提高是促进当前我国蔬菜产业发展的重要因素。经数据包络分析方法测算,2003—2006年期间,我国蔬菜生产技术效率上下波动,2007—2008年开始呈持续上升趋势,规模效率下降是造成技术效率损失扩大的主要原因。2008年我国蔬菜生产技术效率水平一般,生产要素投入冗余较多,规模效率不高但规模报酬递增。因此,为提高我国蔬菜生产技术效率,除合理配置蔬菜生产中的要素投入,还应适当提高我国蔬菜的生产规模。

Technical efficiency is an important factor to promote the development of present China＇s vegetable industry.Based on data envelopment analysis（DEA）,it is found in this paper that,in 2003—2006,the technical efficiency of China＇s vegetable production is in volatility,but in 2007—2008,it is rising.The decline of scale efficiency is the main reason for the further loss of technical efficiency.It shows that,in 2008,the technical efficiency of China＇s vegetable production is at an average level,the production factors input is redundant,and the scale efficiency is low but increasing returns to scale.Hence,in order to improve the technical efficiency of China＇s vegetable production,not only the allocative efficiency of resource inputs should be improved,but also the scale of China＇s vegetable production should be appropriately increased.
