摘 要：
在分析1998~2012年蔬菜种植效益基础上,用DEA数据包络模型对蔬菜种植投入产出效率进行实证分析。结果显示:蔬菜种植成本利润率和产值利润率从2010年开始均有所下降,说明近两年蔬菜种植效益不高;实证分析表明,15年中有5年的投入产出效率处于DEA有效阶段,而其余10年处于规模报酬递增阶段,肥料费和间接费用投入效率相对较低。故建立健全蔬菜投入保障机制和改善生产管理模式是提高蔬菜种植效益的重要举措。

摘 要：
On the basis of analyzing the benefits of vegetable planting in 1998 ~ 2012,the empirical analysis on input- output efficiency of vegetable planting was conducted by the DEA data envelopment model.The results showed that the cost and production value profit margins of vegetable planting had declined since2010. This showed that the vegetable planting benefits nearly two years was not high. Empirical analysis showed there were 5 years whose input- output efficiency was in DEA effective stage. And that of the other 10 years was in the stage of scale returns increasing,and the input efficiency of fertilizer and indirect expenses was relatively low. So establishing and perfecting the safeguard mechanism for vegetable input and improving production management mode were the important measures to improve vegetable planting benefits.
