我国城市工业用水效率与经济发展水平的秩匹配度原理及特征解析
Principle and characteristic analysis of rank matching degree between urban industrial water use efficiency and economic development level in China
摘要
Abstract
The existing matching degree index based on data sequences was improved,and the concept and calculation method of the rank matching degree were put forward.The connotation of matching degree was expanded to three states of under-matching,matching,and over-matching,along with three levels of matching hierarchy,i.e.,high,medium,and low,so as to provide a more comprehensive assessment of the relative development level and matching state of characteristic indicators and influencing factors.The rank matching degree was employed to examine the matching characteristics between industrial water use efficiency(IWUE)and economic development level(EDL)across 336 cities in China in 2017.The findings indicate that cities in the matching state of IWUE and EDL constitute 28.27%of the total,and are distributed across China.Among cities in the matching state,high-level matching cities are mainly distributed in northern areas,and low-level matching cities are mainly distributed in southern areas,such as Hubei and Fujian provinces,as well as Guangxi Zhuang Autonomous Regin.Cities in the over-matching state account for 36.31%,which are predominantly located in North China and Northwest China.The proportion of under-matching cities is 35.42%,which are primarily distributed in Central China,Southeast China,and other economically developed regions with abundant water resources.关键词
