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.

From formality to informality: “Sharing Planners’ as a design method in urban development of Tilanqiao Lilong residential area
(Lodz University of Technology Press, 2023) Wu Yilong; Liu Yuqiu
In the aspect of urbanization, megacities in ‘Third World’ are growing rapidly and constantly searching for ways for development, leading to the current situation of numerous informalized areas in these cities. Learning from the informality development is more viable than the previous dichotomy between First World ‘models’ and Third World ‘problems’ for urban research, since the future of cities lies in those of developing countries. The paper focuses on the informality development in the city center of Shanghai, taking the Lilong residence in Tilanqiao area as an example. One hundred years ago, a formal collection of commercial houses called Lilong was established in Tilanqiao due to the dramatic increase in population in Shanghai. During World War II, a large number of Jewish refugees settled here, creating a culturally mixed community and replacing the uniform architectural style. In the present day, the area has become an informal part of the city center due to lagging infrastructure. On the basis of the participatory and action research methods, the paper concludes a new ‘Sharing Planners’ vision for the informality area from three individual aspects of citizens’ basic needs, commercial vitality and de-gentrification. By focusing on individuals, institutions and policies, experiences and lessons learnt from the development of informality in Shanghai, the former dichotomy statement of distinguish ‘informality’ from ‘formality’ is gradually replaced by a collaborative planning notion: The paper concludes informality, instead of unplanned chaos or exception of best practice but as an essential pattern of considerable relevance for the urban planners in China, thus providing reference for similar cases.

The intertidal zone and waterfront – A study on the morphological mechanism of the marshland zone in the south of Guangzhou city
(Lodz University of Technology Press, 2023) Wu Jianchi; Feng Jiang
This paper analyzes the influence of urban elements on urban plots and their mutual transformation process in history and finds that the intertidal zone plays a key role in the cycle of urban expansion into the river. Historically, river canals and roads were both the transportation lines on which plots depended, while the ramparts fixed the city site, southern city became waterfront area and between the Pearl River was the intertidal zone. With the sedimentation and artificial filling, new levees, waterfront areas and new canals were born in intertidal zone, while old canals silted up into roads or eventually disappeared. However, the construction of the Long-Bund break the cycle, creating a stable hard boundary beside Pearl River and exhausting the scope for expansion of southern city. As a result, the Long-Bund turned to high-rise buildings, forming the financial and commercial center of Guangzhou at that time. On the other hand, it can be observed that the new types of buildings on the Long-Bund were still partly constrained by the logic of traditional plots. The Long-Bund area was the result of a series of historical mechanisms and events.
