Pozycja 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 QiangThe 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.Pozycja Differences of breakfast Spatial Distribution in Real and Virtual Space: An empirical study in the central city of Beijing(Lodz University of Technology Press, 2023) Wang Zhixuan; Sheng QiangThe breakfast service is an important part of local vitality which are traditionally provided by restaurants and street vendors in real space. The booming virtual economy and delivery service provide alternative type. With the outbreak of COVID-19, both the temporary lock-down of many streets and the reduction of travelling have great impact on breakfast service at the beginning of 2020. During this epidemic period, what kind of breakfast service suffers more, if the location matters, these became interesting questions. This paper presents a comparative study on the central city area of Beijing before and after the impact of Covid19. Based on two site surveys in 2019 July and 2020 September, over 3000 breakfast service are mapped in 6 categories in real space. Cell phone data of 2018 and 2020 are also used to provide other factors such as employment/residential densities and distances of commuting. Additionally, social media data of breakfast distribution from Dazhongdianping.com are collected to study how service in real and virtual space overlap. In general, it can be found that the space with dominant accessibility has stronger resilience. Breakfast services in an advantageous position are more likely to expand new opportunities through the network platform in virtual space.
