Abstract
In order to analyze regional difference in optimum allocation efficiency of water-land resources, the article selected panel data of 2011 to make up input-output index system of optimum allocation efficiency on water- land resources. The results of super efficiency in data envelopment analysis show that: firstly, there are some differences among optimum allocation efficiency of water-land resources in different regions of China; secondly, Inner Mongolia, Chongqing, Sichuan, Shaanxi, Hubei, Hunan Guangxi, Liaoning and Shaanxi are located in national final nine; finally, the nine regions are all not relatively effective with less than 100% super efficiency value, and most of these nine regions has inputs redundancy in soil-water erosion controlling, Afforestation of grain for green projects, investment in fixed assets agriculture, forestry, animal, husbandry and fishery; investment in fixed assets management of water conservancy, environment and public facilities.
