| Popis: | 本研究は, 屋外広告物の規制強化が設置状況に及ぼす影響とその因果構造を明らかにするため, 2007年9月に改正された京都市屋外広告物条例を対象に, 現地調査に基づいて, その改正前後における主要幹線街路沿いの屋外広告物の設置状況に関するGISデータベースを構築した. その上で, このデータを用いて, 設置状況変化の因果構造を共分散構造分析により検証した. その結果, 規制強化が改正条例の目的に沿って広告景観の改善に正の影響を及ぼしている一方, 規制強化の意図しない負の影響も存在していることを明らかにした. また, 被規制者の簡易屋外広告物に対する撤去志向が, ひいては, 大型の固定型屋外広告物の面積・色彩・設置高さ・設置位置の改善に影響を及ぼす可能性があることを明らかにした. This study built the GIS database based on two field surveys conducted in 2006 and 2009 before and after revision of Kyoto City Outdoor Advertising Ordinance (2007) to investigate distribution of outdoor advertisements along main streets. Moreover this study clarified causal structure between revised ordinance/tighter control and subsequent changes in distribution of outdoor advertisements, by covariance structure analysis. While the results indicated that the tighter control has had positive effects on the improvement of the advertising streetscape - the objective behind the revision - it was evident that the tighter control also had unintended negative effects. Elsewhere, the willingness of persons subject to the regulations regarding portable outdoor advertising signs to remove such signs was shown to have a direct effect on improvements to the dimensions, coloration, height and placement of large-scale fixed-type outdoor advertisements. |
