Spatio-temporal pattern and influencing factors of urban ecological industrial structure in the Yellow River Basin
Taking 57 prefecture level and above cities in the Yellow River Basin as the research object,this pa-per measures the ecological level of industrial structure from 2010 to 2019 from the three dimensions of industrial structure rationalization,optimization and sustainability,clarifies its spatiotemporal evolution pattern,and re-veals the sources and contributions of the spatial differences of the urban ecological industrial structure in the Yel-low River Basin by applying the Dagum Gini coefficient decomposition method,based on which the influencing factors of the ecological industrial structure are dissected by the spatial Dubin model.The results showed that:(1)From 2010 to 2019,the overall development of the ecological development of urban industrial structure tend-ed to be better,with an average annual growth rate of 1.55%,and the fluctuating trend of the ecological level of urban industrial structure in the downstream,midstream and upstream was basically consistent with the whole.(2)The spatial differentiation of cities was obvious,with high-value areas mainly concentrated in the down-stream areas and low-value areas mostly located in the middle and upper reaches,and the overall evolution of"downstream-upstream"gradient was characterized by a decreasing gradient.(3)The spatial difference of urban ecological industrial structure was gradually narrowing,with an average annual decline rate of 2.47%,The inten-sity of transvariation was the main source of spatial difference,with an average annual contribution rate of 46.45%.The spatial correlation of areas with similar levels of ecological industrial structure decreased,and the phenomenon of spatial aggregation was weakened.(4)The financial development level and consumption struc-ture upgrading level had positive promoting effects on the urban ecological industrial structure,while govern-ment regulation level,industrial agglomeration level and urbanization level had negative hindering effects.Mean-while,consumption structure upgrading level had an obvious positive spillover effect,while government regula-tion level and industrial agglomeration level had negative spillover effects.
