Research on the Urban Network Characteristics of Wuhan Metropolitan Area Based on Baidu Index
Taking Wuhan metropolitan area as the research object,the Baidu index was collected and organized among cities in Wuhan metropolitan area in 2015,2017,2019 and 2021 according to the time series,the urban network model was constructed,and C-Value and D-Value hierarchical analysis,dominant flow analysis,multi-cloud linear regression and other quantitative analysis methods were adopted.The evolution characteristics and influencing factors of urban network pattern in Wuhan metropolitan area were analyzed.The results show that there is a great difference in the level of network connection among cities in Wuhan metropolitan area,and the spatial distribution of information flow presents a disequilibrium feature of high in the east and low in the west,and thin in the east and west.The network hierarchy structure of"core-half edge-edge"is obvious in Wuhan metropolitan area,and the network connection is weak and has the characteristics of spatial proximity effect.Urban information infrastructure,comprehensive economic development level and urban population have significant positive effects on the intensity of urban information network connection in Wuhan metropolitan area.Finally,based on this research,some optimization suggestions are put forward.
