Analysis of the Spatiotemporal Evolution of Industrial Structure Level in the "Ji" Shape Bend of the Yellow River Urban Agglomeration

Abstract

Constructing an industrial structure indicator system, the weights of the industrial structure indicators are calculated by comprehensively applying the entropy method, the mean square deviation method, and the CRITIC method to measure the level of industrial structure in the "Ji" shaped bend of the Yellow River urban agglomeration from 2011 to 2022. Furthermore, the spatial-temporal evolution characteristics of the industrial structure are analyzed. The study concludes that the level of industrial structure in the "Ji" shaped bend of the Yellow River urban agglomeration shows an overall fluctuating upward trend, with significant differences within the region; spatially, it presents a distribution feature of low in the middle and high around the edges, with high-level areas clustering in the northeastern cities, exhibiting a significant spillover effect; finally, suggestions are proposed to facilitate the industrial transformation and upgrading of the "Ji" shaped bend of the Yellow River urban agglomeration.
