产业用水增长质量评价应该耦合水资源约束、经济增长、技术进步与结构变动等因素。在构建中国31个省、市、自治区产业用水变化的全要素分解模型的基础上,基于经济学中的边际思想,计算了1997—2007年中国各地区产业用水规模边际、技术边际与结构边际,并对其进行了时空分异分析。然后计算出中国各地区1997—2007年产业用水增长质量指数,以此来评价产业用水增长质量状况。最后运用空间自相关分析探讨中国产业用水增长质量的空间关联模式。结果表明:研究期内,中国产业用水增长质量总体和局部都呈现提高的态势,与各地区经济发展状况相吻合,产业用水增长质量的空间自相关显著,区域空间差异明显,有很大的提升空间。
Increasing quality assessment of industrial water utilization should be coupled with the factors such as resource constraint,economic growth,technological progress,structural change and so on.Based on the panel dataset of waterutilization and social economy from 1997 to 2007 in China,the industrial waterutilization change of 31 regions was analyzed by using Complete Decomposition(CD) model,and the marginal effects of three major determinants(economic growth,technological changes in restructuring) were calculated based on the marginal thought of economy,then the spatial and temporal difference characteristics of the marginal effects was discussed.In orderto assess the increasing quality of industrial waterutilization,the increasing quality index of all the 31 regions were cclculated from 1997 to 2007.Finally,the Exploratory Spatial Data Analysis(ESDA) method was applied to analyze the spatial association pattern of industrial water utilization increasing quality index.The results show that the increasing quality of industrial water utilization in China has appeared a trend of improvements in all parts and periods,and it also has a coincidence with the regional economic development.There are two significance about increasing quality of industrial water utilization,one is spatial autocorrelation,the other is regional spatial differences,so the increasing quality of industrial water utilization has a big potential to improve.
