Coupling Coordination Degree of Ecological-Economic and Its Influencing Factors in the Counties of Yangtze River Economic Belt

The rapid economic development (ED) of the Yangtze River Economic Belt (YREB) has had a significant negative impact on regional ecosystem services (ES). Accurately understanding and properly handling relationship between ES ED is critical to achieving coordinated YREB. Restricted by minimal number research units, traditional studies have not fully considered spatial heterogeneity influencing factors, leading results with poor accuracy applicability. To address these problems, this paper introduces econometric model explore factors level in For 1013 counties YREB, we used value equivalent method, entropy weight coupling coordination quantify (ESV) from 2010 2020. multi-scale geographically weighted regression (MGWR) was adopted analyze role factors. showed following: (1) degree (CCD) ESV along YREB demonstrated heterogeneity, Sichuan Anhui provinces forming low-value lag. average CCD high low were found Triangle Central China (TOCC), Delta urban agglomeration (YRDUA), Chengdu–Chongqing (CCUA). (2) There autocorrelation distribution CCD, high–high clustering mainly distributed Hunan, Jiangxi, Zhejiang provinces. expanding, centering Kunming City Yunnan Province expanding outward. (3) each factor CCD. Per capita fiscal expenditure sensitive low–low areas CCD; per capita, food production influence, rate urbanization transitioned positive values west east.
