Measurement of Urban Vitality in Tourism Hotels and Analysis of Influencing Factors Based on Multi-Source Data

This study constructs a comprehensive measurement system for urban vitality in tourism hotels based on multi-source data. By integrating hotel operation data, POI data, social media data, and others, urban vitality is assessed from four dimensions: economic, spatial, social, and innovation. The study uses panel data from 15 key tourist cities in China between 2018 and 2022, employing fixed-effect models and moderation effect analysis to reveal the spatiotemporal evolution patterns and driving mechanisms of urban vitality. The empirical results show that leading cities such as Chengdu and Hangzhou exhibit a “Matthew effect” due to digital infrastructure and cultural-tourism integration strategies, hotel operation efficiency has a threshold effect on urban vitality, smart tourism technologies play a moderating role through a triple mechanism of “infrastructure—business synergy—government support.” The research provides a theoretical basis for differentiated tourism policy formulation, and future work should focus on expanding data sources and optimizing algorithms.
