The results show that tourism flows in the Chengdu\u2013Chongqing Economic Circle show a significant \u2018dual core\u2019 polarisation effect. At the end of 2019, as a turning point, the density value of the tourism flow network shows an irregular inverted \u2018U\u2019 distribution. Kuanzhai Alley, Hong Ya Dong and Chunxi Road have irreplaceable competitive advantages in the tourism flow network. The density of highways, the number of star-rated hotels and the regional GDP per capita are positively correlated with the effective size of the structural hole of the administrative unit. Finally, based on the research results, countermeasures are proposed to optimise the tourism development of the Chengdu\u2013Chongqing Economic Circle.<\/jats:p>","DOI":"10.3390\/ijgi12030121","type":"journal-article","created":{"date-parts":[[2023,3,10]],"date-time":"2023-03-10T01:31:41Z","timestamp":1678411901000},"page":"121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Spatial Pattern Evolution and Influencing Factors of Tourism Flow in the Chengdu\u2013Chongqing Economic Circle in China"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2477-9250","authenticated-orcid":false,"given":"Xuejun","family":"Chen","sequence":"first","affiliation":[{"name":"College of Tourism and Media, Chongqing Jiaotong University, Chongqing 400074, China"}]},{"given":"Yang","family":"Huang","sequence":"additional","affiliation":[{"name":"Chinese Village Culture Research Center, Central South University, Changsha 410083, China"}]},{"given":"Yuesheng","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,9]]},"reference":[{"key":"ref_1","first-page":"11","article-title":"Research progress and Prospect of tourism flow in Nanjing University from the perspective of mobility","volume":"5","author":"Zhang","year":"2021","journal-title":"Mod.
