Study On Optimization Of Commercial Spatial Structure In Cities Based On The Saturation Of Business Circle

With the continuous development of the Internet economy,many e-commerce models have emerged,and physical retail is facing great challenges.Some investment and consumption have shifted from the physical platform to the virtual economy,and consumers 'consumption habits are undergoing profound changes.At the same time,the continuous progress of urbanization in our country has promoted the continuous upgrading of urban transportation,real estate,and service industries.The balance between urban commercial supply and commercial demand has been constantly broken,and the urban commercial space structure must also adapt to this change and continue to optimize.How to determine whether the commercial space structure of a city is stable? How to optimize the commercial structure of urban space in an unstable or unbalanced state? This is an important issue that affects the overall planning and layout of the city,and it is also an important issue for urban commercial investors to make scientific judgments.In this study,many indexes of commercial supply and commercial demand are included in the evaluation of business district saturation,and the state of commercial space structure and its optimization direction are judged by evaluating the saturation and change of urban business district.This paper combs the relevant theories about the urban business district and urban commercial space structure and the current research situation at home and abroad firstly.Scholars mainly focus on the urban commercial space hierarchy system,factors that affect the commercial space structure,the layout of business forms,and the choice of business locations.There is less research on the urban commercial space structure from the perspective of urban business circles.There are fewer empirical studies by establishing mathematical models,but the analysis of factors that influence the spatial structure of urban business provides a basis for this study to establish an evaluation index system and build an evaluation model.Therefore,on the basis of deep analysis of the factors that affect the state of commercial space structure in cities,the paper further clarifies the mechanism between commercial supply and demand,business district saturation,and commercial space structure.Afterwards,after referring to the previous research and combining with the optimization evaluation indicators of the actual situation,this paper builds a business district saturation evaluation model,and based on this evaluation model,the business district saturation is measured by taking Chengdu as an example.Based on the business district saturation,the commercial space structure of Chengdu city is analyzed,and the empirical results are basically consistent with the judgment of experts and practitioners in the business field,which proves that the evaluation index is more scientific and reasonable.From the results of theoretical analysis and empirical research,we can see that the change of urban commercial space structure is the result of the joint effect of commercial supply and commercial demand,and it is necessary to judge whether the urban commercial space structure is in a balanced and stable state.It can be carried out through the evaluation of the direct indicator of commercial supply and commercial demand-the saturation of the business district.The saturation of the business district as an early warning indicator of the state of commercial space structure has an important practical significance.On the contrary,by analyzing the merits and demerits of the saturation index of the business district,we can determine the direction of optimization of the commercial space structure.After the warning of the saturation index of the business district,we can analyze whether it is a supply indicator or a demand indicator that needs to be optimized,and even which of them is refined.Indicators,This provides a useful reference for the government to optimize urban planning and investment in enterprise science.Finally,This paper puts forward four suggestions for optimizing urban commercial space structure in four aspects: scientifically layout urban business according to the saturation of urban business district,determine the optimization direction according to the relationship between commercial supply and demand,optimize the internal and external function structure according to the commercial supply and demand index,and build a three-dimensional urban commercial space structure system in coordination with the Internet economy.
