Spatial structure of economy in Hokkaido by the agglomeration of social-capital stock and the organization of industrial cluster

本研究旨在通过社会资本存量的集聚和产业集群的组织来阐明北海道的经济空间结构。首先，分析了交通基础设施发展与产业集聚的关系。其次，考虑交通基础设施建设的公共工程对产业的生产诱导作用。最后，根据上述结果，对北海道的产业集群组织进行了探讨。通过这些分析，北海道的公共投资建设了大量的社会资本存量交通基础设施，商业和工业也在这些交通基础设施附近集聚。但是，新交通基础设施建设的公共投资对工业生产的诱导效应却在下降。公共投资在人口和产业集中的中部北海道表现出最大的生产诱导效应。因此，希望在北海道中部地区实施产业生产诱导的外溢，并产生广泛的经济效果。最后，在北海道产业诱导最为显著的北海道中部地区，探讨产业集群的组织。由此可知，在札幌市形成了生产与技术创新相结合的知识集群。由此可知，社会资本存量的舒适性对北海道的产业集群的组织化做出了贡献。

This study aims to clarify the spatial structure of economy in Hokkaido by the agglomeration of a social-capital stock and the organization of an industrial cluster. First, it analyzes about the relation between traffic infrastructure development and industrial agglomeration. Next, it is considered the production induction of the industry by the public works of traffic infrastructure development. Finally, based on the result, this study argues about the industrial cluster organization in Hokkaido.As a result of these analyzes, many traffic infrastructures as social-capital stock are built by public investment in Hokkaido, and commerce and industry are being agglomerated near this traffic infrastructure. However, it turned out that the industrial production induction effect of the public investment by new traffic infrastructure development is decreasing. Public investment in the Central Hokkaido, which population and industry concentrate, showed biggest production induction effect. Therefore, it is desirable to carry out spillover of the industrial production induction in the Central Hokkaido, and to bring about an economic effect broadly.Finally, in the Central Hokkaido where industrial induction is the most remarkable in Hokkaido, this study is discussed about the organization of industrial cluster. Consequently, it turned out that the intellectual clusters with the association of production and technical innovation are formed in Sapporo City.From the above result, it is solved that the amenity by the social-capital stock has contributed to organization of the industrial cluster in the capital city of Hokkaido.
