“…Hence, it is imperative for the government to optimize the urban population structure, expedite the construction of eco-cities, and refine urban spatial arrangements. Secondly, owing to the implementation of China's high-quality economic development strategy, the impact of economic growth exhibits a "V" shape 75 , 76 . Inadequate investment in green technology exacerbates the adverse trajectory of its impact on coupling coordination 77 , 78 .…”

New urbanization (NU) and ecological welfare performance (EWP) play pivotal roles in achieving sustainable urban development, with both emphasizing social equity and environmental management. Exploring the coordinated relationship between EWP and NU is invaluable for understanding the symbiotic interplay between humans and nature. We constructed a framework to elucidate the coupling mechanism of EWP and NU from the perspective of systems theory. We quantified the levels of NU and EWP utilizing the entropy weighting method and the super-efficient SBM method, respectively. Furthermore, we assessed the degree of coupling coordination between the two using the coupling coordination degree model (CCDM). Spatial and temporal evolution analysis was conducted, and factors influencing the degree of coupling coordination between EWP and NU were explored through a spatial–temporal geographically-weighted regression model (GTWR). The results indicate: (1) During the study period, the average annual increase in EWP in the study area was 2.59%, with a narrowing relative gap between cities. Conversely, the average annual increase in the level of NU was 7.6%, with demographic and economic dimensions carrying the highest weights. (2) The type of coupling coordination between EWP and NU transitions from basic coordination to moderate coordination, with the development of EWP lagging behind that of NU. (3) City size demonstrates a positive yet diminishing trend on the coupling coordination level, with economic development exerting the greatest influence and exhibiting a "V" trend, while the impact of green technology innovation diminishes negatively. Additionally, regional disparities are significant, with city size exhibiting a negative impact in areas of high population density and low economic levels, and green technology innovation showing notable polarization characteristics in core cities. These findings serve as a foundation for fostering coordinated ecological development amid the rapid urbanization process of the Chengdu–Chongqing Economic Circle.

This study investigates the Dynamic Coupling between Land Use Economic Efficiency (LUEE) and Urban Ecological Resilience (UER) in the Yellow River Basin (YRB). This exploration is pivotal for elucidating the interaction mechanisms between economic growth and ecological governance. Furthermore, understanding this relationship is essential for fostering high-quality, sustainable urban development in the YRB. Utilizing panel data from 56 cities spanning 2003 to 2020, this study employed the coupling coordination degree (CCD) model, spatial correlation analysis, Kernel density estimation, convergence model, and Geodetector to systematically analyze the spatio-temporal distribution, dynamic trend, and determinants of the CCD between LUEE and UER in the YRB. The findings indicate that: (1) A general upward trend in both LUEE and UER, accompanied by a steady improvement in their CCD. (2) Significant spatial disparities in their CCD, with higher levels in the lower reaches. (3) Marked positive spatial autocorrelation, predominantly characterized by clusters where high (low) values are surrounded by high (low) values. (4) Regarding the impact of individual factors, government fiscal budget expenditure demonstrates the most robust explanatory power for the CCD within the YRB. Concerning the effects of two-factor interactions, the interplay between industrial structure upgrading and government fiscal budget expenditure emerges as the most significant determinant in influencing the CCD between LUEE and UER. This study enhances our comprehensive understanding of the interplay between economic and ecological systems. It offers scientific insights and strategic direction for harmonizing ecological governance with urban economic growth at both the regional and global scales.

“…This paper estimates the coupling and coordination level of the economic system and ecological system in the Chengdu-Chongqing urban agglomeration area from 2005 to 2019 and uses a local indicator of spatial association analysis to illustrate its spatial distribution. This paper measures the coupling and coordination degree of new urbanization and ecological environments in various provinces in China and analyzes the spatial correlation between the coupling degree and the coordination degree [18]. The Thiel index is a tool for analyzing differences.…”

The construction of ecological civilization is an important part of the cause of Chinese socialism, and the evaluation of the construction of ecological civilization and the differentiated analysis of its synergistic development will guide the coordinated development and coordinated ecological governance and protection in China. Synergistically, an evaluation index system was constructed based on the social–economic–natural multisystem, and the deviation coefficient coupling coordination model was used to evaluate the construction of the ecological civilization of 83 cities in the region from 2000 to 2020. The spatial and temporal development characteristics were explored using the spatial autocorrelation index and standard deviational ellipse, and the urban–rural differences were quantitatively analyzed by using the Thiel index. The results show that from 2000 to 2020, the degree of coordinated development of the social–economic–natural multisystem in different cities was low, and there are different reasons for cities with different urban–rural divisions. In this study region, the spatial distribution of the social–economic–natural coordinated development of cities is becoming increasingly discrete, and the center of urban distribution, which has a higher level of coordinated development, is gradually shifting to the southwest. In 2020, the level of coordinated social–economic–natural development in the study area was significantly different in urban and rural areas.
