Evaluation of industrial ecological security in industrial transformation demonstration area based on spatiotemporal differentiation

Abstract

Evaluating the state of China's industrial transformation and its ecological protection is essential to addressing industrial ecological security. In this study, nine cities in the Wanjiang Demonstration Zone were selected for analysis using the normal cloud model and the spatial autocorrelation model. The study results showed that (1) the industrial ecological security of the Wanjiang Demonstration Zone showed an upward trend from 2012 to 2019, and the development among cities was unbalanced; (2) the industrial ecological security level in the northeast of the Wanjiang demonstration zone was higher than that in other cities; and (3) the spatial correlation within the demonstration area is positive, and the degree of agglomeration is strong initially but is subsequently attenuated. This indicates that enhancing the ecological security of the city will have a backflow effect that will attenuate connection with surrounding cities. This study elucidates ecological security in the industrial transformation demonstration area, and the following recommendations are made based on the research results: improving the strategic planning of regional industrial ecosystems, creating a new governance pattern featuring coordinated development among regions, and innovating new business forms and models for the development of inter-city linkage.
