Taking Lanzhou\u2010Xining urban agglomeration as a case, the urban connection intensity and high\u2010quality development level were measured to analyze the relationship between them. From 2012 to 2018, the UCI and HDI of each city showed different degrees of growth. Note that there exist significant regional differences, with Lanzhou and Xining having the largest difference. The biggest gap among cities lies in the innovative connection intensity. Moreover, urban external connections are closely related to high\u2010quality development, especially innovation and green development. For every 1% increase in industrial and transport connection, the HDI will increase by 0.317% and 0.159%, respectively. This study provides a methodological reference for measuring urban connectivity and provides decision support for high\u2010quality development in China and other countries.<\/jats:p>","DOI":"10.1155\/2021\/9933582","type":"journal-article","created":{"date-parts":[[2021,11,3]],"date-time":"2021-11-03T18:50:09Z","timestamp":1635965409000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Exploring Coupling Relationship between Urban Connection and High\u2010quality Development Using the Case of Lanzhou\u2010Xining Urban Agglomeration"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3486-9594","authenticated-orcid":false,"given":"Junfeng","family":"Yin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0390-9140","authenticated-orcid":false,"given":"Haimeng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peiji","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiping","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,11,3]]},"reference":[{"key":"e_1_2_10_1_2","volume-title":"Urban Complexity and Planning: Theories and Computer Simulations","author":"Shih-Kung Lai H.
