Water Resource Utilization Efficiency And Disparities In Spatial Correlation Pattern Research In Liaoning Province

Shortage of water resources is an important factor restricting the sustainable development of the revitalization of northeast old industrial base and the social economy in Liaoning province.Water footprint and water resources utilization efficiency measure of Liaoning province provide important theoretical basis for adherence to ecological red water resources environment.Water footprint measures water resources system of human occupied directly and it is one of the most effective indicators to measure the impact of human life and production activities on the water resources ecological environment system currently.Based on the panel date of water footprint of 14 cities in Liaoning Province,this paper estimated the water footprint and water footprint intensity of every city in Liaoning Province from 2004 to2013,then found that water footprint intensity has obviously decrease tendency and water footprint intensity has great difference of every city in Liaoning Province.By constructing the kernel density estimation model describes the dynamic evolution trend of per capita water footprint and water footprint intensity and by using the Theil index and Tsui-Wang index explore that water footprint intensity is in the direction of the balanced development,this explains that water resource utilization efficiency has a difference reduce trend.There exists a significant spatial effect of water footprint intensity among cities of Liaoning Province,in these influence factors,the per capita GDP and propretion of industrial water consumption have negative influence and the per capita water footprint and education funds have positive influence,these factors are harmful to improve the water resources utilization efficiency.Based on the water footprints then established the water resources utilization absolute and relative efficiency of every city in using stochastic frontier analysis,date envelopment analysis modeling.By the Gini coefficient and variable coefficient,found that the difference reduced and converged for water resource utilization efficiency.The water resource utilization absolute and relative efficiency of Shenyang,Dalian,Anshan and Panjin are on a higher level,while Fuxin and Chaoyang are the lowest.The characteristic of geographical location is distributed across the central inland to southern coastal region and spreads east and west,gradually diminishing in entirety.The water resources utilization relative efficiency of Liaoning is in state of a gradual increase,the gap in water resource utilization absolute efficiency of every city is shrinking.Using cluster analysis to study the spatial-temporaldifferentiation of water resource utilization efficiency,based on the spatial weighting matrix,we found spatial autocorrelation of water resources utilization efficiency.High-high correlation pattern areas are mainly distributed at the economic level in relatively developed cities in Liaoning,such as Dalian,Anshan,Panjin and other regions.Low-low correlation pattern areas tended to be less developed cities,such as Fuxin,Chaoyang and Huludao.High-low and low-high correlation pattern areas occur between high-high and low-low correlation pattern areas.Enhancing the water resource utilization efficiency of low-low correlation pattern areas will promote the water resource utilization efficiency of surrounding areas,and this is conducive to increasing the overall water resource utilization efficiency across Liaoning.
