本文研究結論發現：1.亭仔腳設置第一階段為明治39年（1906）嘉義市遭遇大地震後配合市區改正計畫而施行，第二階段為1930年代嘉義市改制整頓市容時。大正年間亭仔腳劃設為粗略的規定，但昭和年間劃設的範圍是配合商業發展及都市政策，同時市區改正計畫中也將亭仔腳劃設納入規定。2.嘉義市亭仔腳規制訂定及修正施行次數共計9次，明治43年（1910）規定較為概略，首次制定於大正2年（1913），在昭和3年（1928）、昭和8年（1933）、昭和11年（1936）、昭和12年（1937）大幅修正。3.昭和12年（1937）嘉義市設置亭仔腳規制與其他城市並無多大差異，但昭和時期嘉義市亭仔腳規制修正極為頻繁，顯見當時都市快速發展。4.由嘉義市亭仔腳規制的構造細部及寬度規定發現，即使是臺南州下的各市鎮亭仔腳寬度也略有不同，法規中對於亭仔腳耐震補強的規定隨著建築研究的進步而調整。

Conclusions and findings of the study are: 1) The relationship between arcade construction and Chiayi City's spatial transformation can be examined in two stages: the first stage started after a major earthquake hit the city in 1906. The arcades were part of the urban area correction program. The second stage started after the city was promoted as an autonomous city. After the promotion, the city initiated efforts to enhance its appearance. 2) There are totally 9 versions of planning codes for arcades in Chiayi City, including their first version and subsequent revisions. As the codes formulated in 1910 were rather broad, the first version of the codes is deemed as completed in 1913 with substantial revisions in 1928, 1933, 1936, and 1937. 3) These codes used to have distinctive features during the early Showa period. However, the codes in 1937 did not vary substantially from codes for other cities in Taiwan in terms of width of the front road, width of the arcades, their height, recess of columns and runoff slope considered in formulating the codes. 4) Analysis of provisions of detailed structures and width in Chiayi City's codes for arcade shows that even towns under Tainanshu also had slightly different arcade width.
