【摘要】：基于辽宁省14个城市的水足迹面板数据,计算2004—2013年辽宁各城市的水足迹和水足迹强度,辽宁省水足迹强度明显下降,各城市间水足迹强度存在很大差异。采用核密度估计模型、基尼系数、锡尔指数分析人均水足迹和水足迹强度的动态演变规律,辽宁省水足迹强度差异在不断缩小且有收敛趋势。空间自相关检验发现,辽宁省水足迹强度存在显著空间自相关关系,高高集聚区域主要分布在辽宁省经济欠发达的城市,如阜新、朝阳、葫芦岛;低低集聚区域主要集中在辽宁省经济水平相对发达的城市,如大连、鞍山、盘锦;辽宁省水足迹强度存在显著空间效应,其中人均水足迹对水足迹强度的影响最大。
[Abstract]:Based on the water footprint panel data of 14 cities in Liaoning Province, the water footprint and water footprint intensity of each city in Liaoning Province from 2004 to 2013 were calculated. Gini coefficient, Sier index analysis of the per capita water footprint and water footprint intensity dynamic evolution law, Liaoning Province water footprint intensity difference is shrinking and convergence trend. Spatial autocorrelation test found, There is a significant spatial autocorrelation relationship between water footprint intensity in Liaoning Province. High agglomeration areas are mainly distributed in less developed cities of Liaoning Province, such as Fuxin, Chaoyang, Huludao; The low and low agglomeration areas are mainly concentrated in the cities with relatively developed economic level in Liaoning Province such as Dalian Anshan Panjin and the water footprint intensity of Liaoning Province has significant spatial effect among which the per capita water footprint has the greatest influence on the water footprint intensity.
