Urban Commercial Space Evolution And Land Use Planning Response

The development of urban commerce is influenced by the process of urban construction.Many factors,such as the evolution of urban spatial layout,improvement of traffic conditions,and migration of population distribution,are affecting commercial development.Commercial space carries commerce.In the context of "Internet plus",on the one hand,location orientation,consumer preferences and other factors that once affected the layout of commercial space still play a role,on the other hand,e-commerce in full swing has brought long-lasting impact on commerce,and a new layout structure of commercial space is taking shape.Therefore,it is of great significance to understand and study the evolution of commercial space layout.This article takes Changchun City as an empirical case.Firstly,it uses research methods such as nuclear density analysis and Getis Ord Gi* index method to explore the overall scale and evolution characteristics of commercial spatial layout of various business types in Changchun City.Secondly,according to the urban space construction process and commercial project construction process led by the urban development strategy,the period from 1996 to now is divided into three development stages,and the dynamic mechanism of the development of commercial space in Changchun is analyzed.Finally,starting from three aspects of planning concept,planning connotation,and planning practice,this paper proposes planning opinions responsive to the layout of urban commercial land,providing ideas for the urban economic development of Changchun City.The research results show that the layout of commercial space in the central urban area of Changchun has experienced a complete process from "spreading big cakes" type expansion to the formation of a "dual center,two wings,and multiple clusters" urban spatial structure,and then to the determination of the dual center commercial structure of the old commercial center in the north and the new city in the south.This complete process has been formed under the guidance of urban development strategies,the improvement of road and rail transit construction,the migration of population in suburban areas,and the impact of the formation of dynamic mechanisms driven by ecommerce.Therefore,planning opinions responsive to the layout of urban commercial land are proposed from three aspects: conceptual response,connotation response,and practical response,providing direction for the development of commercial space layout in Changchun City.
