The assessment of public participation is one of the most fundamental components of holistic and sustainable cultural heritage management. Since the beginning of 2020, the COVID-19 pandemic became a catalyst for the transformation of participatory tools. Collaboration with stakeholders moved online due to the strict restrictions preventing on-site activities. This phenomenon provided an opportunity to formulate more comprehensive and reasonable urban heritage protection strategies. However, very few publications mentioned how social networking sites’ data could support humanity-centred heritage management and participatory evaluation. Taking five World Cultural Heritage Sites as research samples, the study provides a methodology to evaluate online participatory practices in China through Weibo, a Chinese-originated social media platform. The data obtained were analysed from three perspectives: the users’ information, the content of texts, and the attached images. As shown in the results section, individuals’ information is described by gender, geo-location, celebrities, and Key Opinion Leaders. To a greater extent, participatory behaviour emerges at the relatively primary levels, that being “informing and consulting”. According to the label detection of Google Vision, residents paid more attention to buildings, facades, and temples in the cultural heritage sites. The research concludes that using social media platforms to unveil interplays between digital and physical heritage conservation is feasible and should be widely encouraged.

Urban waterfront public space is a key infrastructure for enhancing citizens’ well-being. However, rapid urbanization squeezes out blue and green spaces in cities, and extreme weather challenges exist in winter cities, resulting in unmet needs and a significant decline in citizens’ satisfaction. There is an urgent need to optimize design to bridge the gap between supply and demand. This study proposes a workflow for optimizing the design of waterfront spaces in winter cities based on the KANO-IPA model from the perspective of users’ demands. We constructed a systematic and comprehensive set of spatial demand indicators for waterfront public space in winter cities, covering seven demand dimensions and 42 indicators. A satisfaction survey was conducted across 12 sample reaches in northeastern China. We used the KANO model to classify the attributes of spatial demand indicators, then applied IPA analysis to evaluate them, and finally calculated priority indices to quantify their priority sequences. Based on this, we proposed three-phase optimization strategies: near-term priority upgrading, medium-term steady promotion, and far-term charm enhancement, offering recommendations for improving waterfront public spaces in winter cities. This study provides long-term support for urban regeneration, resource management, and waterfront public space design in winter cities.

China is undertaking effective actions to adhere to wider international standards with better consideration of the notion of authenticity, collective memory, identity, and the sense of belonging. Besides the traditional participatory management discussions, scholars are also interested in finding out how the ICTs can encourage and enable new forms of engagement with heritage in different cultural contexts. The article offers an innovative approach to understanding the value of community participation in order to obtain a more sustainable way for integrative approaches in cultural heritage management. It focuses on the identification of criteria for the evaluation of Digital Community Engagement (DCE) and proposes the multivariate evaluation model based on the online questionnaires and face-to-face interviews. The result shows that the transparency of the restoration process, the possibility of adopting bottom-up suggestions, and the coherency with the residents’ interests are the most important factors to influence the Willingness to Participate and the Willingness to Pay. The analysis based on theme-coding is essential to understand the opinions of various stakeholders with different educational and professional backgrounds. It concludes that multi-disciplinary and value-based methods should be encouraged as an exploratory way of enhancing community engagement in the specified urban heritage context.

The use of social media has played a significant role in influencing individuals' perceptions of community resilience, particularly in the face of global disasters. The study focuses on the city of Harbin in northeastern China to examine public responses to the pandemic and to assess perceived community resilience in regions severely affected by recurrent epidemics in a spatio-temporal context using social media data. The results of the study show that urban centers, characterized by high population density and well-developed urban infrastructure, had the highest level of public concern about the epidemic. In addition, users associated with universities and research institutions showed positive attitudes towards the epidemic. Public reactions were most pronounced during periods of strict prevention and control measures, with an increase in out-break-related tweets and a prevalence of negative sentiment. The study highlights the differences in reactions between people from different backgrounds and the impact of the epidemic and related prevention and control measures on different aspects of daily life. Based on the findings, policy measures are proposed to improve urban epidemic preparedness, covering both physical infrastructure and human factors. This study contributes to a deeper understanding of the Chinese urban context and provides valuable insights for urban planning and management in underdeveloped regions.
