The Association between District Vitality and Industrial Structure Based on Quantitative Analysis in a Historic District: A Case Study of Xuanen Xinglong Historic District, China

This study explores the association between district vitality and industrial structure in historic districts through a quantitative analysis of the Xuanen Xinglong Historic District. In this study, on the basis of multisource data, we constructed the framework of a quantitative analysis system for the association between historic district vitality and industrial structure to explore the reasons for the decline in historic district vitality and propose strategies and recommendations for creating vitality in historic districts. The findings reveal that (1) the vitality of the Xuanen Xinglong Historic District showed a higher middle area than the surrounding area and more rest days than working days; (2) in terms of functionality, the degree of aggregation of POIs in catering, shopping and consumption, living services, and recreation and sports in the Xuanen Xinglong Historic District is high; and (3) the impact of POI data on district vitality is more significant for shopping and consumption and catering, followed by company and enterprise, hotel and accommodation, and recreation and sports, with other types of POIs having a weaker impact. The results can guide strategies for industrial upgrading and cultural tourism development for Xuanen Xinglong and other historic districts facing similar challenges.
