The analysis of spatial coupling between commercial outlets and street morphology at the county level:A case study of Taicang City in Jiangsu Province
摘要
Abstract
Road network morphology affects residents'travel and shapes the commercial form of the city.This study examines the spatial relationship between commercial outlets and road network in Taicang,China,a rapidly developing county-level city,and the size and capacity of its commercial outlets lag behind its economic development.The research aims to provide valuable insights into the interplay between commercial development and road network morphology,which can inform more effective commercial development strategies and planning.The spatial characteristics of the commercial outlets are analyzed through various indicators,such as kernel density,average nearest neighbor index,and standard deviation ellipse.The study selects grade density index as road geometric features and spatial design network analysis(sDNA)as topological features of the road network to develop a composite index of road network morphology to analyze the coupling between commercial outlets and road network. The results show that:(1)The core of the spatial distribution of commercial outlets in Taicang is the same as the core of the spatial distribution of the road network comprehensive index.There is a large clustering core in the main urban area of Taicang and small clustering distribution in each town.The clustering degree of different types of commercial outlets is different.(2)The direction of commercial distribution in Taicang is a northeast-southwest trend,and the street network distribution is in a north-south direction.Leisure and entertainment types and restaurants are distributed more"east-west".(3)The measures describing the morphology of the street network have a significant relationship with commercial outlet density.The NQPDA index of the sDNA model has the greatest explanatory power on the distribution of commercial outlets,but the TPBt index has the weakest correlation.The catering outlets have the greatest correlation coefficient with all the morphology parameters of the road network.(4)A high correlation between commercial outlets and road network in Taicang,primarily exhibiting a high-high or low-low coupling pattern.It suggests that areas with well-developed road network tend to have a higher concentration of commercial outlets,while areas with less developed road network have fewer commercial outlets.However,the study also reveals that approximately 29%of the analyzed areas show incomplete coupling,with road network outpacing commercial development in urban regions and the opposite occurring in rural areas.It highlights the need for a more nuanced understanding of the relationship between commercial outlets and road network in Taicang and the importance of considering this relationship with formulating commercial development strategies. Additionally,the authors suggest constructing roads to connect different regions and capitalize on the high composite indices of the Taicang-Liuhe expressway.It could help to improve overall commercial development in Taicang by increasing accessibility between different areas and promoting the growth of commercial centers in areas with high road network composite indices.By considering the spatial relationship between commercial outlets and road network,it is possible to create a more cohesive and effective commercial development plan for Taicang. This research offers valuable insights into the spatial relationship between commercial outlets and road network in Taicang,demonstrating that business centers in areas with high road network composite indices are likely to be more successful due to increased accessibility and potential customer attraction.Furthermore,building roads to connect various areas could improve overall commercial development in Taicang by fostering greater connectivity between different regions and promoting the growth of business centers in areas with high road network composite indices. One limitation of this study is its focus on static spatial characteristics,which may not fully capture the dynamic nature of traffic flow and its impact on commercial patterns.Future research could incorporate dynamic traffic flow indicators to further explore the impact of road network on commercial layout,providing a more comprehensive understanding of the relationship between commercial outlets and road network in Taicang. In conclusion,with the accelerated urbanization in China,understanding the relationship between commercial outlets and road network becomes more important for effective urban planning and commercial development.This study provides essential information for policymakers and stakeholders involved in commercial development planning in Taicang.The findings can inform more effective decision-making and ensure the commercial development aligns with the road network morphology.By considering the spatial relationship between commercial outlets and road network,a more cohesive and effective commercial development plan for Taicang can be created.This study provides a valuable foundation for future research that seeks to explore the complex interplay between commercial development and road network morphology.关键词
