Abstract

Starting with the brief analysis of current utilization of water resources in 13 cities in Jiangsu province, input oriented, this thesis evaluated the changes and differences of production and living water use efficiency among the cities in Jiangsu from 2005 to 2014 based on data envelopment analysis’s C2R model. In general, water utilization efficiency of the whole province as well as every city was improving in the last decade. There are obvious differences of water use efficiency among these cities, despite the similar escalating trend in the perspective of time sequence. 13 cities in Jiangsu Province are divided into four types regarding their level of water use efficiency by K-means clustering analysis. Cities in demand of improving water use efficiency can learn from cities of higher water use efficiency. Economic development has great influence on water use efficiency. Generally speaking, efficiency of water utilization is higher in the developed cities; the higher GDP per capital. This faster water use efficiency grows. The present redundant inputs of the cities showing invalid water use efficiency reveal extra resources allocation, which can be theoretically resolved to arrive at the optimal equilibrium point through the analysis of the DEA projection.
