Poyang Lake Ecological Economic Zone, a traditional rural area in Jiangxi province, whose grain production holds an important status in the pattern of food production in Jiangxi province. This paper empirically analyzes Total Factor Productivity (TFP) changes of grain in 25 counties (cities) in Poyang Lake Ecological Economic Zone by adopting DEA-Malmquist index model. The result shows that TFP of grain in Poyang Lake Ecological Economic Zone increased from 2000 to 2010 on the whole. In addition, the principal element of the increase is technological progress. Further analyzing its decomposition, it is known that the increase of TFP mainly comes from technological progress. Separately, TFP of four counties (cities) including Yongxiu county, Ruichang city, Yujiang county and Guixi city decreased while the other 21 counties’ all increased. Thus, corresponding policy suggestions is put forward on this basis.
