Urban Commercial Location Study Based On Space Syntax

With the increasingly rapid advance of urbanization in China, investigating and utilizing city space structure evolution principles to serve the city planning and construction are becoming more and more important. Space Syntax has became one of the most significant urban modeling methods for its emphases on space subjectivity and quantification. This paper discussed the feasibility of using Hierarchical Linear Model as a solution to Modifiable Areal Unit Problem and analyzing city commercial location under multi-scale spaces based on axial models, and then carried out a case study of Jinan to provide a reference for city spatio-functional form studies in future.In the case study, this paper set up city-level and district-level axial maps of Jinan in2011and2020according to Jinan City Regulatory Plan, and calculated the values of connectivity, control, integration n and integration3of each axis to reveal city spatial characteristics. General linear regression models and hierarchical linear models were exploited to investigate the relationship between spatial structure and commercial activity intensity which was quantified by C.B.D ratio. A prediction model was also constructed in terms of the two-level hierarchical linear model to find out the preferred commercial location of Jinan in2020and compare with the commercial distribution pattern proposed in regulatory plan. As the result suggested, the syntactic indexes under different spatial scales had different impacts on Jinan commercial location choice:in the district-level, the main influencing factors were integration3and connectivity; in the city-level, the main influencing factors were integration n and integration3. To sum up, the urban commercial locations were mainly determined by district-level integration3, connectivity and city-level integration n. This finding should be carefully considered in the process of city planning and construction.
