| ［目的］为识别三峡库区各区县的农业发展转型中的问题并提出对策， 2006—2014年库区农业全要素生产率作出测算，并进行空间关联分析。［方法］利用DEA Malmquist指数法测算2006—2014年的三峡库区及各区县的农业全要素生产率并分解； 采用空间自相关模型分析三峡库区农业全要素生产率的时空特征及空间关联。［结果］在提高农业全要素生产率促进农业转型的过程中，除2006年外，三峡库区农业全要素生产率处于提升状态； 各区县的农业全要素生产率具有显著的空间正相关性和明显的空间集聚结构； 各区县因表现出技术效率、技术进步偏低等特征，使库区不同区县出现全要素生产率偏低和技术效率滞后于技术进步等方面的问题，形成了库区农业发展转型问题的空间异质性。［结论］加快三峡库区农业转型发展，需结合不同区县的发展问题，充分利用空间相互作用，采取政府统一部署、区域差异化政策以及推广农业科技等策略。 |

| Abstract: |
| To identify problems of agriculture transformation development in all counties of Three Gorges reservoir area and put forward suggestions, this paper analyzed the agricultural total factor productivity (TFP) from 2006 to 2014 and the spatial auto correlation of agricultural TFP. The agricultural TFP of the total reservoir area and all counties were calculated and decomposed by means of DEA Malmquist index. Space time features and spatial correlation of the agricultural TFP were analyzed by the spatial auto correlation model. The results showed that in process of improving the agricultural TFP to promote agriculture transformation, agricultural TFP of the reservoir area was in state of rise in all the years except 2006. There were obvious spatial positive correlation and spatial agglomeration structure among agricultural TFP of each county. Because of low technical efficiency and low technological progress, these problems such as low total factor productivity and technical efficiency′s lagging behind technological progress in different counties resulted in spatial heterogeneity of the agricultural transformation and development in the reservoir area. In order to promote the agriculture transformation development in Three Gorges reservoir area, these measures should be considered such as implementing unified government deployment, adopting different regional policies, and promoting agricultural science and technology, based on the development situations of different counties and making full use of space interaction. |
