Digital technologies are transforming how China protects its urban and rural heritage, from sub-millimetre scans of Buddhist carvings to digital twin platforms that monitor entire ancient cities in real time. Yet a new qualitative study of 30 representative Chinese projects argues that these gains are being undermined by structural problems: missing technical standards, algorithmic bias against minority architecture, departmental data silos, and community participation that remains largely symbolic. The research, published in Frontiers of Urban and Rural Planning, examines how digital tools contribute to sustainable conservation and where their empowering effects break down.
Cases were screened to exclude projects where technology remained conceptual or information was incomplete, and selection covered the full technological chain from data acquisition to dissemination, diverse heritage types including ancient sites, historic buildings, cave temples and intangible cultural heritage, and different governance models spanning government-led, enterprise-partnered and community-involved arrangements. Using thematic analysis, the researchers assessed applications across three functional dimensions: digital recording and documentation, digital management and conservation, and digital education and dissemination.
The clearest achievements lie in documentation precision. The Digital Collection and Documentation of Buddhist Temple Ruins in Xinjiang deployed a drone swarm to build centimetre-level accuracy models of 82 sites, producing a structured database exceeding 15 terabytes. In Shaoxing, multi-source technologies achieved millimetre-level reality modelling and dynamic documentation management for the entire ancient city. At the micro scale, the 3D modelling project at Longmen Grottoes used fine-scale photometric stereo technology to capture carving traces shallower than 0.05 millimetres without contact, enabling algorithmic detection of early-stage weathering damage. At the Yungang Grottoes, muon imaging technology performed what the authors describe as zero-intervention internal CT scans of the rock mass, locating hidden cavities and seepage channels.
Management platforms show similar advances. A risk monitoring and early warning platform for grotto temple clusters established a two-tier Internet of Things system spanning regions and individual sites, shifting practice from reactive rescue towards proactive prevention. The digital twin system of Liangzhu 5000+ integrates data from multiple departments, using 55 sensor groups and AI video analytics to achieve intelligent environmental risk perception and automated early warning with reported accuracy above 95 percent. Applied research has also yielded discoveries: drone aerial surveying and AI image recognition applied to Great Wall heritage quantified spatial characteristics such as wall gradients and led to the identification of more than 130 previously unrecorded covert gate remains.
Public engagement has moved from static display to immersive experience. The Mawangdui Han Dynasty immersive digital exhibition uses 4K laser projection and a dome screen to translate archaeological findings into a large-scale sensory experience, while Digital Luoyang reconstructs the Northern Wei dynasty city through visual restoration and sound-based narrative. Digital Dunhuang uses high-precision digital restoration to let tourists observe otherwise inaccessible cave interiors through a mobile application. The Silk Road Online Museum established a transnational cloud curation platform attracting thousands of global participants in creating digital exhibitions.
These findings support what the authors characterise as a paradigm shift from static preservability to dynamic sustainability, tracing an evolution through three phases: a digital documentation period from 1960 to 2002 focused on salvage recording, a digital interpretation period from 2003 to 2018 marked by 3D scanning, virtual and augmented reality and international charters, and a digital reconstitution period from 2019 onwards in which digital twins and remote collaboration make the digital dimension a core component of the heritage value system rather than an auxiliary archival tool.
However, the study identifies serious bottlenecks. The digital standardisation system is underdeveloped: Historic Building Information Modelling standards designed primarily for modern or European traditional buildings lack support for Chinese traditional, ethnic minority and vernacular architecture, causing frequent data loss and distortion during information transfer. No nationally unified technical standard for digital documentation of historical buildings yet exists. Algorithmic bias compounds the problem. AI systems frequently misidentify ethnic minority buildings, such as Lingnan ethnic buildings along the Xiaoshui-Hezhou Ancient Road in Guangxi, as derelict structures or roads, because training datasets contain insufficient samples of ethnic architecture. Similar risks affect stilted dwellings in Qiandongnan, mosques and shrines in northwest China, Dai bamboo dwellings in Yunnan and Tibetan stone tower houses, which the authors describe as a form of digital cultural exclusion.
Governance capacity lags behind the technology. Departmental data silos are identified as the most significant institutional obstacle. Although Guangdong’s unified mobile office platform links 11 departments, the Cultural Heritage Bureau of Guangzhou holds data permissions limited to two levels, and 40 percent of the city’s cultural conservation data is not integrated with the urban construction platform. Legal frameworks are similarly lagging: China lacks specific legislation for digital heritage protection, with existing provisions scattered across the Cultural Relics Protection Law, cybersecurity and data security laws, leaving data ownership, privacy and digital copyright in a compliance grey zone.
Socio-ethical conflicts deepen these challenges. A 2021 survey of 196 elderly residents by the Suzhou Survey Team of the National Bureau of Statistics found 46.4 percent found smart products cumbersome to use and 54.6 percent could not remember usage instructions, excluding some older residents from VR-based heritage interpretation. Rural connectivity gaps compound the divide: 5G coverage in rural China is reported at less than one-third of urban levels, and in Qiandongnan only 64 of the prefecture’s 415 nationally recognised traditional villages, roughly 15 percent, were listed on the Chinese Traditional Villages Digital Museum by 2025. Even where participation is nominally open, it tends to be formalised: the Guangzhou Memory digital museum drew over a million annual visits but minimal resident contributions, and in Suzhou’s Huqiu project residents acted mainly as data providers rather than co-interpreters. The authors also flag an authenticity crisis, noting that some commercial apps for projects such as Digital Dunhuang restoration omit the annotation of historical sources required by the London Charter, leaving the public unable to distinguish archaeological evidence from artistic conjecture.
The study traces these problems to an underlying governance logic that prioritises technical rationality over humanistic values such as cultural accuracy and community narrative sovereignty, and proposes a rebalancing framework. Technically, it recommends differentiated strategies: high-precision tools for cities and lightweight, low-cost solutions such as mini-programs enabling villagers to document local heritage in rural and minority regions, alongside a multi-ethnic architectural database to correct algorithmic misclassification. Institutionally, it proposes an inputs-mechanisms-outputs governance model with legal data ownership, mandatory open data standards for publicly funded projects, intellectual property sharing agreements defining the rights of communities, technology firms and governments, and performance indicators such as an interoperability score and community uptake rate. Ethically, it calls for preserving non-digital participation channels, simplified interfaces and voice input to bridge the digital divide, and an ethics-aligned benchmarking matrix aligned with international charters. As evidence of feasibility, the authors cite Guangzhou’s Yongqingfang, where a digital community map collecting resident feedback reportedly increased resident participation by over 40 percent. China’s state-led approach, the study concludes, excels at mobilisation and large-scale rollout but must evolve towards a state-led polycentric model in which communities become genuine partners rather than spectators in the digital afterlife of their own heritage.
