Efficiency evaluation of provincial input-output based on DEA in rural China

Data Envelopment Analysis (DEA) is an effective measure tool to evaluate the regional input-output efficiency. After the brief review of existing literature, as well as the principle of DEA, this paper evaluates the input-output efficiency of China´s 31 provinces (municipality) via the approach of DEA. The result shows that there are respectively three, one and three provinces from east, center to west are efficient in rural input-output. Moreover, the average efficiencies of the three regions are very close, and the effect of different region is not significant to rural input-output.
