AB - Jilin is an important grain producing area and heavy industry base in China.  With the economic development and improvement of people's livelihood, water  resource issues have been becoming increasingly prominent, Jilin Province  comprehensive utilization of water resources is not efficient. The  traditional method of water consumption per 10000 Yuan of output value  cannot objectively reflect the water-use efficiency of different local  industrial structures. Therefore, this paper builds the data envelopment  analysis model based on the input-output relationship. In order to meet the  requirements of data envelopment analysis model for data analysis, this  paper introduces the principal component analysis method, and reduces the 16  water resources input indicators and 14 water resources output indicators  of Jilin Province from 2004 to 2017 to 3 input principal components and 2  output principal components. The multi-model data envelopment analysis  method is used to analyze the water-use efficiency of Jilin Province, and  the results show that with the rapid economic growth, the water resources  efficiency in 2010-2013 was relatively poor, there was a waste of water  resources, and the management technology was backward, but with the  deepening of the industrial transformation and upgrading, farming  modernization and revitalizing the strategy of the old industrial base in  Northeast China, the water-use efficiency and the water resources carrying  capacity of Jilin Province has been improved.
