Abstract: The summer resort tourism market has become a current research hotspot in tourism studies. The summer resort and residence functions of Qujing City by integrating multi-source information systems, including user-generated content (UGC), questionnaire surveys, and Baidu migration data, heve been analyzed to reveal several deficiencies in the summer resort and residence functions of Qujing City, such as a single tourist demographic structure, insufficient tourism experience and residential functions, a lack of leisure and entertainment functions, and an insignificant urban brand effect. Accordingly, Qujing City needs to construct an urban resort and residence function system consisting of 5 major categories and 10 subcategories to develop summer resort and residence tourism. The advantages should be leveraged in summer resort and residence by optimizing the tourist demographic structure, upgrading supporting facilities, strengthening digital marketing, and deeply integrating culture and tourism, so as to optimize its summer resort and residence functions and promote the industrial transformation and upgrading of Qujing City.

Key words: Qujing City, summer resort and residence, urban functions, multi-source data, promotion paths
