General Research into the Social and Economic effect Influenced by Construction of the Big Bridges

通过对本州大桥-史比国大桥建设所产生的社会经济效益进行分析，得出如下结论：本州-四国大桥给人们和塞斯内海地区带来了很大的影响。它给他们带来了良好的心理效果，行动方便，缩短了从四国地区到本州地区的行动所需时间。因此，许多游客来到四国，旅游业蓬勃发展。一些主题公园开业，位于四国地区的新工厂数量增加，就业增加。但本州-四国大桥的影响是暂时的。几年过去了，游客和新植物的数量迅速减少。以松山市斗湖温泉地区为例，许多日式酒店已经倒闭，数量从1988年的61家减少到2002年的37家。为了充分利用本州四国大桥，我们必须将依赖外部大公司和国家S补贴的区域发展政策转变为内生性的区域发展政策。

By the analysis of the social and economic effect influenced by construction of the big bridges, Honsyu-Sbikoku Bridges, it is developed as follows. Honsyu-Shikoku Bridges brings much effect to people and the area of the seth inland sea. It gives them mental good effect, convenience for movement and shortens the time needed for movement from Shikoku area to Honsyu area. Consequently, many tourists came to Shikoku and the tourist industry was brisk. Some theme parks opened The number of new plants locating in Shikoku area and employment increased. But the effect of Honshu-Shikoku Bridges was transitory. After a lapse of several years, the number of tourists and new plants has decreased rapidly. For example, in Dogo hot springs area in Matsuyama city, many Japanese-style hotels have gone bankrupt and the number of them decreased from 61 in 1988 to 37 in 2002.To make the most of Honsyu Shikoku Bridges, we have to change the regional development policy, which is dependent upon the outside big companies and the nation s subsidy, into endogenous regional development policy.
