    The spatial resilience of the community’s commercial vitality: Comparative study on spatial renovation of Beijing Hutong district before and after
    (Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang; Zeyang Xu
    Based on Baidu Street View time machine and field survey data, this paper analyses the changes of community businesses before and after spatial renovation in Hutong district, which covers an area of 7 square kilometres in central Beijing from 2015 to 2020, and uses space syntax model to analyse the distribution rules and trend of changes. The results show that although the total amount of business in the community and the commercial location of each subdivision of business community have a sharp fluctuation, in essence, the location of commercial agglomeration and distribution in the community is very stable before and after renovation, and has a high correlation with the standardized Angle choice parameter of 1000m radius. In addition, after renovation, the correlation between community commercial distribution and population density, urban commercial density, public transportation convenience and other three parameters is improved, reflecting the spatial resilience brought by spatial connection behind the functional change.

    Research on Quantitative Evaluation and Influencing Factors of the Vitality of Newsstand – an example of Beijing
    (Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang; Li Xinyi
    Newspaper kiosks used to be cultural Windows of cities, but in the data era, they face many challenges of survival and problems of future renewal. At the micro level, this study obtained the total number of transactions of 25 existing kiosks and the number of transactions of each derivative function through field research and carried out a quantitative evaluation on the vitality of kiosks based on this. The paper further analyses the explanatory power of five parameters, including population density, commercial function, topological form, geometric form and street walkability, on the vitality of the existing newsstands. At the macro level, based on Baidu Street View time machine, this study obtained the spatiotemporal differentiation data of 277 newsstands in the western part of Beijing which covers an area of about 160 square kilometres (2013–2021) and compared the difference of the above five parameters of the death and the existing newsstand space in an eight-year time span. In this way, we can reveal the reasons that affect the vitality of the newsstand for a long time. It is found that the walkability and population density are the main factors affecting the vitality of newsstands, both in the existing newsstands and the newsstands within a period of eight years. In terms of each function, the correlation between the number of transactions of newspapers and periodicals and the number of transactions of life and retail functions and the two parameters of walkability and commercial function density are different. On this basis, the paper puts forward some strategies, such as function updating and space positioning updating, in order to provide reference for the demolition, construction and urban renewal of the newsstand in the future.

    Spatial Resilience of Local Places: A comparative study on Beijing’s breakfast service before and after Covid-19
    (Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang
    The distribution of breakfast services under the impact of COVID-19 provides an ideal case for studying the supporting role of urban space on self-organized commerce. Based on the large-scale, multi-type and high-precision field survey of breakfast services in the central urban area of Beijing in 2019 and 2020, this paper analyzes the distribution pattern of breakfast services by using topological spatial accessibility based on spatial syntax, combined with the work-housing and commuting density data obtained by mobile signaling. Statistics showed that after the epidemic, the total amount of breakfast decreased and the distribution imbalance was further aggravated but the location of the gathering center was stable. Breakfast services on high topological accessibility streets are more likely to survive. Regression analysis showed that residential density had a greater effect than working density except for breakfast in the supermarket. Streets with high topological accessibility and close to subway stations have a stable supporting effect on the survival of breakfast services.
