Abstract: Data envelopment analysis （DEA） was used to evaluate the production efficiency of cultivated land in Guiping city of Guangxi from 2007 to 2016. The results showed that the development of production efficiency of cultivated land in Guiping city was in a fluctuating state from 2007 to 2016. Malmquist productivity index method is used to analyze the change of total factor productivity, the productivity only declined in 2009. Tobit model was used to analyze the influencing factors of cultivated land productivity in Guiping city. The multiple cropping index, the proportion of irrigation area and the average total power of agricultural machinery had significant effects, and the average total power of agricultural machinery had negative effects. The multiple cropping index and the proportion of irrigation area had positive effects. The production efficiency of cultivated land in Guiping city needed to be improved.
