We studied the urban competitiveness of Southwest cities in China using factor analysis. Two factors were extracted among 22 original variables. The factor score of cities was obtained using Python and were classified into three categories: Chongqing, Chengdu, Kunming and Guiyang are the first-tier cities; Baoshan, Pu’er, Lincang and Lijiang cities are of the lowest tier; the remaining cities belong to the second tier.</abstract><keywords/></article-meta></front><body/><back><ref-list><ref id="B1" content-type="article"><label>1</label><element-citation publication-type="journal"><p>Si S, Sun X, (eds) 2020, Mathematical Experiment and Modeling in Python, Science Press, Beijing.</p><pub-id pub-id-type="doi"/></element-citation></ref><ref id="B2" content-type="article"><label>2</label><element-citation publication-type="journal"><p>Wu X, 2019, Multivariate Statistical Analysis with R and Python, Renmin University of China Press, Beijing.</p><pub-id pub-id-type="doi"/></element-citation></ref><ref id="B3" content-type="article"><label>3</label><element-citation publication-type="journal"><p>Xue W, 2007, SPSS Statistical Analysis Method and Application.
