Abstract: Agricultural production efficiency determines the level of rural regional economic development and the quality of people's life. The mode and structure of rural land use in Anhui province are changing constantly. By constructing multi-factor evaluation index, the land use efficiency was analyzed comprehensively by using data envelopment analysis. The results showed that the comprehensive efficiency of rural land use in Anhui province showed an increasing trend, and there were significant differences among different regions. Therefore,to improve the utilization efficiency of rural land use, we should strengthen the service function of the government, perfect the infrastructure construction, perfect the supporting system of land circulation and enhance the value of land resources.
