The development of the Great Wall National Cultural Park has unleashed the potential for integrating cultural and tourism development along the Great Wall. However, ICH along the Great Wall, a key part of its cultural identity, suffers from low recognition and a mismatch between protection and development efforts. This study analyzes provincial-level and above ICH along Hebei’s Great Wall using geospatial tools and the Geographical Detector model to explore distribution patterns and influencing factors, while Geographically Weighted Regression is utilized to reveal spatial heterogeneity. It tests two hypotheses: (H1) ICH shows a clustered pattern; (H2) economic factors have a greater impact than cultural and natural factors. Key findings show: (1) ICH distribution is numerically balanced north–south but spatially uneven, with dense clusters in the south and scattered patterns in the north. (2) ICH and crafts cluster significantly, while dramatic balladry spreads evenly, and other categories are random. (3) Average annual temperature and precipitation have the greatest impact on ICH distribution, with the factors ranked as: natural > cultural > economic. Multidimensional interactions show significant enhancement effects. (4) Influencing factors vary spatially. Population density, transport, temperature, and traditional villages are positively related to ICH. Elevation, precipitation, tourism, and cultural institutions show mixed effects across regions. These insights support targeted ICH conservation and sustainable development in the Great Wall cultural corridor.

The sustainable protection of cultural heritage is essential for the intergenerational transmission of cultural diversity and represents a central theme in the United Nations Sustainable Development Goals (SDGs) on “heritage resilience governance”. To address the policy sustainability challenges of large-scale linear heritage governance, this study examines the characteristics and shortcomings of Great Wall Cultural Preservation (GWCP) policies during its steady implementation. To analyze how policy instruments are distributed, whether policy objectives are synergistic, and whether stakeholders’ participation is reasonable, this study uses GWCP policy texts issued by China from 2006 to 2024 as research objects and establishes a three-dimensional analytical framework (“instrument–objective–stakeholder”). With the help of the NVivo 20 tool, the study analyzes the policy texts in one dimension and multiple dimensions, and finds that China’s GWCP policy has shortcomings in sustainability governance, such as the imbalance in the use of policy instruments, the overflow of contextual policy instruments, the government’s over-exertion of force, the need to release the functional space of stakeholders, and the lack of attention to the synergy between the goals of conserving architectural heritage and safeguarding the Great Wall ethos. Based on these findings, the study proposes three targeted optimization recommendations. This GWCP case study offers developing nations insights into balancing heritage protection objectives under SDG 11.4 with local development needs.
