Research on Spatial Pattern Evolution and Driving Factors of Urban Consumption Vitality:a Case Study of the Main Urban Area of Hefei
Taking the main urban area of Hefei as an example,using POI data and combining kernel density analysis,average nearest neighbor index,and standard deviation ellipse,the evolution process of urban consumption vitality space from 2012 to 2020 is analyzed,and the driving factors affecting urban consumption vitality are studied using geographic detector.The results show that:(1)The consumption spatial pattern has evolved from"single core diffusion"initially to"multi core connection",gradually evolving from point axis to block spatial pattern in spatial form.(2)In terms of spatial evolution trend,the consumption vitality space mainly presents a development trend from northeast to southwest,while the development trend from north to south is relatively weak.(3)In terms of spatial evolution rate,the agglomeration degree of urban consumption vitality space increased from 2012 to 2016,and showed a slowing trend from 2016 to 2020.(4)The transportation service capacity and public service level have strong impacts on the urban consumption vitality,and there is a dual factor enhanced interaction among various driving factors.
