Spatial Characteristics and Influencing Factors of the Coupling and Coordination of High-Quality Development in Eastern Coastal Areas of China

Abstract

China’s pursuit of sustainable and healthy economic growth requires the promotion of high-quality development. While many scholars have studied high-quality development, few have examined the coupling and coordination among its internal systems. The study aims to analyze the influencing factors of high-quality coordinated development, identify problem areas based on the five development statuses, and provide practical recommendations for optimizing the spatial layout of high-quality development in these areas. By applying a coupling coordination model and a geographically weighted regression model, the comprehensive level of high-quality coordinated development in the eastern coastal areas was evaluated. The results revealed that the majority of the eastern coastal region exhibited weak coordination and significant spatial differences in their comprehensive level. The problem cities were predominantly located in the southern and northern coastal areas. An economic foundation and innovation potential have a positive and stable impact on high-quality coordinated development.

Spatiotemporal Evolution, Coupling Coordination Degree and Obstacle Factors of Urban High-Quality Development: A Case Study of Anhui Province

“…The HQDI distribution of the subsystems confirms the severity of the spatial gradient differences. Some studies have paid attention to the CCD of high-quality development from different perspectives [17,[29][30][31][32][33][34][35][36][37]. These studies found that the CCD of high-quality development in some cities has not yet reached a high level [17,35,36].…”

“…They found that counties in Zhejiang Province have an intermediate coordinated degree [17]. Yuan et al found that most cities in the eastern coastal areas of China have weak coordination degrees and obvious internal differences [37]. However, there is a lack of measurement of the internal coupling coordination relationships between the high-quality development subsystems.…”
