Assessing city sustainable development—Residents' quality of life from the perspective of sustainable development goals and spatiotemporal evolution

Abstract

AbstractScientific evaluation of the sustainable development efficiency of China's large and medium‐sized cities has far‐reaching significance to how to improve the well‐being of residents and improve the level of sustainable development. This research uses the parallel two‐stage SBM dynamic (PT‐DSBM) model to evaluate the sustainable development efficiency of 33 cities in eastern, central, and western China. The innovation of this article is divided into two points. First of all, the PT‐DSBM model is used to subdivide the sustainable development system into social, economic, and ecological subsystems and closely integrates it with residents' QOL, which further reveals the inherent mechanism of the sustainable development system. Second, the spatiotemporal evolution can further reveal the spatiotemporal changes of sustainable development and residents' QOL within the scope of this investigation. The results show the following. (1) The overall efficiency of urban sustainable development in China is high in the east and west and low in the central. (2) The social subsystem efficiency in western cities exhibits outstanding performance, eastern cities perform better in economic and ecological sustainable subsystems, while the efficiency of residents' QOL remains at a high level in the sample cities as a whole. (3) In the study of spatiotemporal evolution, the concentration of urban sustainable development decreases with time evolution. Finally, this research gives suggestions on social security, stakeholder engagement, and environmental policies.
