This paper analyzes the citrus input-output efficiency by using the DEA-Malmquist productivity index methods based on the data of six counties in Jiangxi Province from 2010 to 2013. The result shows that TFP of Jiangxi citrus is at low level overall, but the development is rapid. Technological progress is the driving force to promote productivity growth. Based on the static analysis study of six counties in 2013, it is found that the available input factors on the whole are in an ideal condition, and the citrus input factors in a few counties are redundant. Therefore, according to the results, the following policy recommendations are proposed: speeding up the intensive production of citrus in Jiangxi Province, to maximize the scale effect; adjusting the input ratio of various factors of production, so as to improve the citrus input-output efficiency.
