Evaluation and Factor Analysis for Urban Resilience: A Case Study of Chengdu–Chongqing Urban Agglomeration

Abstract

Resilient cities provide a new operating mechanism for sustainable urban development and can effectively reduce urban disaster losses. Urban resilience has become an important research topic, but few scholars focus on the urban resilience of urban agglomerations in western China. Therefore, this paper takes the Chengdu–Chongqing urban agglomeration of China as the study area and aims to evaluate the resilience level of cities in typical regions of western China. This study uses multiple interdisciplinary methods, such as the entropy weight method, Theil index, and geographically and temporally weighted regression, to evaluate the resilience levels of 16 cities in the region and discuss the influencing factors of regional urban resilience. The results show that the urban resilience of cities in the Chengdu–Chongqing urban agglomeration has evolved from a low to high level. Additionally, there are significant spatial differences in urban resilience in the Chengdu–Chongqing urban agglomeration, and the resilience levels of cities in the east and west of the region are relatively high, while the resilience levels of cities in the south and north are relatively low. Further research found that factors such as administrative level, marketization level, industrial structure, population density, urbanization level, and emergency facility level all have a significant positive impact on the improvement of urban resilience, but this impact has spatial and temporal heterogeneity. Based on the above research results, the strategies have been proposed from the perspective of sustainable urban development to provide a new theoretical support and decision-making reference for improving the resilience level of urban agglomerations in western China.

An Empirical Examination of the Coupling Coordination Development of Energy Environment and Socioeconomic: A Case Study of the Yangtze River Economic Belt in China

“…To properly evaluate the coupled coordination between EE subsystem and SE subsystem, it is essential to establish a comprehensive evaluation system, as shown in Table 1. The design of this system should consider the principles of systematization, comprehensiveness, scientific rigor, and operability, while also referring to relevant studies by scholars such as Jochen et al [46], Shen et al [47], Xing et al [48], Daniel et al [49], Zheng et al [50], and Yin et al [51]. By establishing a conceptual and cognitive framework for the connotation of coupling and coordination between EE and SE, we can better recognize the mutual promotion role between EE and SE, providing a scientific basis for formulating corresponding policies and measures.…”

Spatiotemporal characteristics and driving mechanisms of coupling coordination of pseudo human settlements in urban agglomeration in eastern China

“…"Coupling coordination" is the process of coordinating and interacting among multiple systems or subsystems. The term "coupling" originated in physics 14 and has been extensively utilized in research within economics [15][16][17] , ecology [18][19][20] , tourism [21][22][23] , geography [24][25][26][27] , and various elds. Applications in HS have concentrated on the following aspects: (1) the coupling coordination within the internal system of HS 28,29 ; (2) the coupling coordination among different states of HS 7 ; (3) the coupling coordination between HS and the external system 30 .…”

Classification and Planning Strategies of Multidimensional Resilience Units for Urban Waterlogging: A Case Study of the Old City District in Shijiazhuang, China

“…This ensures that sufficient resources can reach disaster points in a timely manner, expediting emergency responses and recovery processes. It emphasizes preparedness, safety, and adaptability and is assessed using seven factors, including emergency shelter density, regional medical facility density, road space GSI rate, and waterlogging evacuation capacity [41][42][43]. (4) Rapidity is the ability to complete tasks in a timely manner according to priorities to ensure the normal operation of the system.…”
