Analysis on the synchronized development between urbanization process and eco-efficiency through the sustainability lens.

Urbanization and eco-efficiency are two interactive systems, contributing to sustainable urban development jointly. However, the synchronized development between them has not received sufficient attention. In light of this gap, this paper conducts an analysis on seeking the synchronized development between sustainable urbanization and eco-efficiency in the context of China. The aim of this study is to uncover the spatial and temporal performance of the synchronized relationship between urbanization process (UP) and eco-efficiency (EE) in a sample of 255 Chinese cities. To this end, entropy method, super efficiency SBM and coupling coordination degree model are employed to conduct the research analysis, covering the period of 2005 to 2019. The findings of this study reveal that (1) there is about 97% of the surveyed cities that exhibit a moderate level of coupling coordination between urbanization process and eco-efficiency (CC-UE). (2) Spatial disparities in the performance of CC-UE are evident, with cities in South and Southeast China demonstrating better CC-UE performance than their counterparts. However, this disparity has been gradually diminishing in recent years. (3) Local perspective presented an evident spatial autocorrelation within the 255 cities analyzed. These research findings provide valuable insights not only for the policy-makers and practitioners to adopt measures for achieving a synchronized development between urbanization process and eco-efficiency in the Chinese context, but also for further studies on sustainable development in the international context.
