... Many studies have focused on shrinking cities, mainly in countries and cities that have experienced population decline due to hollowing out of industries (Audirac, 2018;Baba & Asami, 2017;Beauregard, 2009;Bernt, 2016;Couch & Cocks, 2013;Deng & Ma, 2015;Fol, 2012;Franklin, 2021;Galster, 2019;Ganning & Tighe, 2015;Ganning & Tighe, 2021;Haase et al., 2014;Haase et al., 2017;Haase et al., 2021;Hackworth, 2016;Hartt, 2018a;Hartt, 2018b;Hartt, 2020;Hartt & Hackworth, 2020;Hoekveld, 2014;Hollander, 2011;Hollander, 2018;Huuhka, 2016;Martinez-Fernandez et al., 2012a;Martinez-Fernandez et al., 2012b;Miyauchi et al., 2021;Mouratidis, 2019;Murgante & Rotondo, 2012;Olsen, 2013;Park & Heim LaFrombois, 2019;Schilling & Logan, 2008). Most of them are demographic-based case studies of shrinking cities, historical considerations, and the analysis of the characteristics or common factors of shrinking cities (Beauregard, 2009;Bernt, 2016;Franklin, 2021;Hoekveld, 2014;Hollander, 2018;Martinez-Fernandez et al., 2012a;Martinez-Fernandez et al., 2012b;Murgante & Rotondo, 2012). Studies have also been conducted on the examination of promoting compact cities due to population decline and their appropriate scale (Audirac, 2018;Ganning & Tighe, 2021;Haase et al., 2014;Hackworth, 2016;Miyauchi et al., 2021;Park & Heim LaFrombois, 2019;Schilling & Logan, 2008). ...
