| 摘要: |
| 随着我国人口数量的上升和居民消费水平提高，蔬菜的消费需求不断增加，蔬菜生产和供应的稳 定增加至关重要，而提高蔬菜生产效率是保证供应稳定的重要途径。运用面板数据DEA分析法——— Malmquist指数法计算了2003～2009年全国27个大中城市露地番茄生产的全要素生产效率值，并将各地区 的全要素生产率分解为技术变化、纯技术效率和规模效率。通过对计算结果的分析认为，我国经济发达地 区新技术的投入水平较高，但全国范围内对已有技术的利用程度较低，我国露地番茄的生产效率还有很大 提升空间。 |

| Abstract: |
| As the population growth， China needs more vegetable consumption in the future. It's very important to ensure vegetables supply and enhance the efficiency of vegetable production. The Data Envelopment Analysis for panel data-Malmquist index was used to analyze production efficiency of tomato in the open ground in 27 cities of China from 2003 to 2009， and decompose the total factor productivity（TFP） into technical change， pure technical efficiency and scale efficiency. The results showed that the investment in new technologies was high in well-devel- oped areas， but most of technologies had not been well used. Production efficiency still had great space to be im- proved. |
