Spatio-temporal characteristics and coupling coordination factors of industrial water resource system resilience and utilization efficiency: A case study of the Yangtze River Economic Belt

Abstract

With the rapid expansion of urbanization and the intensification of climate change, industrial activities have increased the uncertainty faced by water resource system. The coordinated development of industrial water resource system resilience (RIWRS) and utilization efficiency (EIWRU) has become the current goal. In this paper, the coupling coordination model was used to analyze the interaction between RIWRS and EIWRU in the Yangtze River Economic Belt (YEB), and back-propagation artificial neural networks were constructed to investigate the crucial factors influencing coupling coordination levels. The results of this study showed: (1) RIWRS in YEB fluctuated upward from 2011 to 2021, with the growth rate decreasing in the order of “upper-middle-lower reaches,” and EIWRU in YEB showed a “W” trend. (2) The relationship between RIWRS and EIWRU transformed from antagonism to adaptation to coordination stage, with an overall improvement of coupling coordination degree. (3) The coupling coordination relationship was developing, and its influencing factors were constantly changing. The antagonism, adaptation, and coordination stage were primarily influenced by natural resource endowment, environmental protection level, and technological innovation level, respectively. This study can enrich the relevant research framework, which can also provide theoretical references for the YEB and even global industrial water resource sustainable development.
