In the present study the assumed hypothesis that there is a considerable degree of interdependence between the degree of urbanization and the development level of a transportation system has been examined in the case of 59 municipalities in Ehime prefecture. For this purpose, first, the degrees of urbanization, and the development levels of transportation systems, of the municipalities were quantified by way of a principal component analysis, to the results of which were then applied regression analysis and analysis of variance, respectively, so as to find out relationships between them and their significance. Finally, residuals, or differences between the observed and predicted values of the degrees of urbanization were calculated, the sources of which being then inquired into. The results of these analyses may be summarized as follows: 1. As a result of the principal components analysis applied to the 49 variables which represent regional characteristics, the urbanization degree factor is obtained as the primary factor that can explain 38.8 per cent of the total variance. This shows the significance of the degree of urbanization as the fundamental dimension for the regionality of the prefecture. 2. The principal components analysis of the 17 variables for the levels of transportation systems yields five principal components with eigenvalues over unity. Of these five the first factor referring to terminal facilities for transportation explains as much as 41.2 per cent of the total variance. From this it turns out that the development level of a transportation system can be estimated to a large extent by the terminal facilities factors. 3. Our conclusions based on the results of the regression analysis and analysis of variance are: (1) there is a significant interdependence between the degree of urbanization and the development level of a transportation system, and (2) the larger portion of the variation in degrees of urbanization can be estimated in most cases in terms of the terminal facilities of the municipalities. 4. An inspection of the residuals reveals that the samples consist of two major groups. Group I having high values with positive loadings and Group 11 having high values with negative loadings, the former of which is further composed of three subgroups. A, B and C. From a further examination of the residuals for the subgroups is derived our conclusion that they are closely related to the historical backgrounds and regional characteristics of each of the municipalities here considered.

本研究は,地方中小都市における中心商店街の再生について,愛媛県今治市の仲間型組織である「今治商店街おかみさん会」(以下,今治おかみさん会)を事例に選び,その設立背景となる商業環境の変化と活動実態の分析から考察を進めた.高度経済成長期に工業の好況を背景に隆盛を極めた今治市の中心商店街は,1990年代後半以降,大店法の運用緩和に伴う郊外地域での大規模な商業集積の形成としまなみ海道開通の影響を受け,その衰退が決定的となった.今治商工会議所,今治市役所,今治商店街協同組合は大規模な再開発構想や空店舗対策など,様々な再生策を打ち立てたが,その多くは不調に終わり,中心商店街の再生は行き詰まりをみせていた.このような状況からの打開策として,松山市で女性による商店街のまちづくりに関する実践を知った今治市役所商工労政課の提案を受けて2000年11月に設立されたのが今治おかみさん会である.今治おかみさん会は,既存の商店街組織である今治商店街協同組合とは独立しており,話題性の高い共同事業を独自で継続的に展開することで中心商店街の再生に寄与する組織のひとつとなっている.しかし,行政からの補助金削減と会員店舗の減少により,今治おかみさん会の運営は厳しい状況にある.今治市の事例からは,商業活動の衰退が進む地方中小都市の中心商店街では,規模の縮小を前提に,既存の枠にとらわれない仲間型組織が再生の一翼を担う可能性をもつことが明らかになった.
