Spatiotemporal evolution of coupling coordination between highway and economic development in Shandong province
In order to study the interaction of highway and economic development in Shandong province,the index system of highway and economic development is established,and the combined weight method of entropy value method and AHP are used to assign the index weight,and the development level of the two is measured;the coupling coordination analysis model is established and the coupling degree and coupling coordination degree are calculated.This paper studies the evolution characteristics of highway and economic development level and their coupling coordination from time and space dimension respectively.The result shows that from 2011 to 2019,the level of highway and economic development in Shandong province kept rising,and highway traffic was always ahead of economic development,and both of them showed a spatial pattern of"high in the east and low in the west-dual-core prominence".The coupling degree of the two has always been high and stable,and has entered a period of coupling coordination in an all-round way,showing a spatial pattern of"continuously decreasing to the surrounding area with the Ji-Qing Channel as the agglomeration axis".The coupling coordination degree of the two has an obvious trend of increasing gradually,realizing the evolution from basic coordination to moderate coordination;the spatial pattern is more stable than the coupling degree,showing the characteristics of"Ji-Qing dual-core agglomeration".There are significant regional differences in their development,so promoting regional balance will become an important focus of highway and economic development in the next step.
