黄河流域产业智能化与生态效率的耦合机制及演化特征OA

Promoting the coordinated and coupled development of industrial intelligence and ecological efficiency is an essential pathway for implementing the major national strategy of ecological protection and high-quality development in the Yellow River Basin.In order to provide support for formulating differentiated coordinated development policies in the Yellow River Basin,this study analyzed the coupling and coordi-nation mechanism between industrial intelligence and ecological efficiency.Utilizing data from 60 cities in the Yellow River Basin from 2007 to 2021,the coupling coordination degree model was applied to measure the coupling coordination degree(CCD)between the two.Addition-ally,the Gini coefficient and Gaussian kernel density model were employed to explore the spatial disparities and dynamic evolution character-istics respectively.The results show that:a)The CCD between industrial intelligence and ecological efficiency in the Yellow River Basin ex-hibits a persistent upward trajectory.It progresses from barely coordinated to favorably coordinated,exhibiting a spatial gradient pattern of"low in the upper reaches,high in the lower reaches".All three sub-regions(upper,middle and lower reaches)maintain sustained and rap-id growth.The CCD between industrial intelligence and ecological efficiency in prefecture-level cities exhibits a distinct characteristic of"co-existence of overall improvement and internal disparities".b)The overall disparity in the CCD between the two exhibits a declining trend;Nevertheless,spatial heterogeneity remains pronounced.Specifically,the between-group gap between the upper and lower reaches is the dominant source.c)The non-equilibrium of the CCD is diminishing over time,and no tendency toward polarization is observed.
