This paper use DEA method to analyze the factor allocation efficiency of the 196 farmers in ten main litchi producing areas in China in 2013.The results show that the average technical efficiency in nine litchi main producing areas is only 0.600,which indicates that the production factor allocation of the inefficient areas is not reasonable.Pure technical efficiency of the litchi main producing areas is lower than scale efficiency.Low efficiency of the integrated technology is mainly dueto scale inefficiency,which needs to suit one’s measures to local conditions to allocate reasonably ratio of input factors of production,to increase investment in science and technology,to promote the reform of the agricultural extension system,and to provide effective technical guidance and training for farmers.
