黄河流域资源型城市新质生产力发展的时空演进研究OA

In order to provide a reference for resolving the problems of resource curse and ecological constraints in resource-based cities in the Yellow River Basin and promoting the sustainable development of the basin,an index evaluation system covering three dimensions of new quality laborers,new quality labor objects,and new quality labor materials was constructed.The entropy weight-TOPSIS method was used to assess the new quality productive forces development level of 34 resource-based cities in the Yellow River Basin from 2012 to 2023.The spa-tial-temporal evolution pattern of the new quality productive forces level was measured using kernel density estimation and the grey prediction GM(1,1)model.The obstacle degree model was used to analyze the influencing factors of the new quality productivity level.The results show that:a)Among the resource-based cities in the Yellow River Basin,the number of cities in the rapid growth type is the largest,and the av-erage level of new quality productivity shows an inverted V-shaped growth trend.b)The development of new quality productive forces in these cities tends to converge,and the forecasted average index from 2024 to 2028 demonstrates a stable upward trajectory.c)The top five obstacle factors affecting the development of new quality productivity are the growth rate of broadband access users,the density of road lines,the proportion of fiscal science and technology expenditure,the ratio of R&D personnel to employed personnel,and the intensity of waste gas emissions.
