摘要：

This paper estimates the eco-efficiency of farming activity at a provincial scale in China based on Data Envelopment Analysis model. The results show that provinces in central area presented relatively lower eco-efficiency, the western provinces are higher eco-efficient, while provinces in eastern provinces are low or high eco-efficiency. It also indicates that provinces with higher crop production usually have lower eco-efficiency, which proves that Chinese crop production deeply depends on resource input.
