Sustainable Heritage Tourism in Transition: Policy, Space, and Authenticity in a UNESCO World Heritage Site

Heritage cities confront persistent tensions between safeguarding cultural authenticity and facilitating sustainable heritage tourism within rapidly modernizing urban contexts. This study examines these dynamics through Pingyao Ancient City, a UNESCO World Heritage Site exemplifying both conservation achievements and tourism challenges. Employing a mixed-methods framework, the research synthesizes GIS-based spatial analysis, multi-scalar policy assessment, media discourse analysis, and stakeholder interviews with residents, tourists, and heritage managers. Findings reveal substantial land use transformations characterized by internal functional restructuring with 212% and 300% expansion of service and commercial land use, respectively. While regulatory frameworks demonstrate efficacy in preserving architectural integrity, they simultaneously constrain adaptive reuse and experiential engagement. Media narratives and interviews illuminate pervasive authenticity concerns (86% among stakeholders) despite acknowledged infrastructural improvements. The analysis validates that static preservation paradigms, while achieving technical objectives, potentially undermine destination competitiveness by privileging physical conservation over cultural vitality and holistic visitor experiences. This study posits that sustainable heritage tourism necessitates integrated policy frameworks reconciling conservation imperatives with adaptive spatial strategies, dynamic community engagement, and authentic cultural interpretation. These findings contribute to heritage management theory while offering practical implications for policy formulation in comparable contexts.
