长三角城市群生态系统服务与经济高质量发展的耦合协调机制
Analysis of coupling coordination between ecosystem services and high-quality economic development in the Yangtze River Delta Urban Agglomeration
摘要
Abstract
As one of China's strategic regions with the strongest economic base,the highest level of openness,and the most robust innovative capacity,the Yangtze River Delta urban agglomeration shoulders the dual missions of promoting high-quality economic development and fundamentally enhancing environmental quality.Examining the intrinsic relationship between ecosystem services(ES)and high-quality economic development(HQED)can provide a scientific foundation for the region's green and low-carbon circular economic growth.Employing the Yangtze River Delta as the study area,this study comprehensively applied methodologies including the In VEST model,entropy weight method,coupling coordination degree analysis,Dagum Gini coefficient,kernel density estimation,spatial auto-correlation model and spatial Durbin model to examine the trends of ES and HQED from 2005 to 2020,with particular emphasis on characterizing the spatiotemporal dynamics and elucidating the driving mechanisms underlying their coupling coordination relationship.The results show that:(1)From 2005 to 2020,both the ES index and the HQED index in the Yangtze River Delta maintained a positive growth trajectory,although the total growth rate of the ES index was lower than that of the HQED index;(2)The coupling coordination degree between ES and HQED within the Yangtze River Delta from 2005 to 2020 has steadily increased,with all cities were out of the moderate discoordination,and some of them have already achieved primary by the end of the study period;(3)The Gini coefficient first rises and then falls,indicating that the overall difference of the coupling coordination degree widened initially and narrowed subsequently,highlighting an urgent need to address inter-and intraregional imbalances.(4)Environmental regulation,human capital level,urbanization level,population density and green equity trading all exert statistically significant positive direct effects on the local coupling coordination degree between ES and HQED,and generate significant positive spatial spillovers.These factors not only propel the local coupling coordination level to leap forward,but also drive the synergistic enhancement of coupling coordination level in neighboring regions through technology diffusion and market integration.By taking ES as the entry point and integrating it with HQED into a unified analytical framework,this study traces the spatiotemporal evolution of their coupling coordination.It scientifically identifies strengths and weaknesses of different regions across the Yangtze River Delta,and thereby guiding regional spatial planning and the rational allocation of resources,provides a scientific basis for high-quality regional coordinated development and for creating a model of harmonious coexistence between humans and nature.关键词
