  • Distribution of Industrial Growth in Nagoya Metropolitan Area, Japan: An Exploratory Analysis Using Geographical and Technological Proximities, Eri Yamada, Tetsu Kawakami, REGIONAL STUDIES, REGIONAL STUDIES, 50(11), 1876 - 1888, 2016 , Refereed
    Summary:This study explores the spatial pattern of industry dynamics in Japan's motor metropolis of Nagoya. Exploratory spatial data analysis methodologies that reflect aspects of both geographical and technological proximities within regional industries are proposed and applied to the long-term, sustained manufacturing and service sector growth rates. The descriptive results identify the presence of positive multilayered growth clusters, driven mainly by the automobile and associated industries. These growth clusters differ in sectoral composition and geographical scale; the larger specialized growth cluster of transportation equipment encompasses the smaller one composed of diverse manufacturing and service sectors.

    Summary:In this paper, we first apply the methods of exploratory spatial data analysis and investigate the geographical concentration of interrelated growing industries, or "growth clusters," by using data from the Nagoya metropolitan area in Japan over the period 1986-2006. Second, by applying econometric models, we examine whether and which type of knowledge externalities contribute to region-industry dynamics and to the formation of the detected growth cluster. As a methodological contribution, following Porter's (Reg Stud 37:549-578, 2003) widely recognized cluster concept, we incorporate spatial dependence caused by the geographical proximity between regions and the technological proximity between industries into the empirical models. Combining the information obtained from the ESDA and econometric analysis enables us to assess the role of knowledge externalities for regional growth from a cluster perspective. The empirical results identify the presence of a growth cluster mainly driven by the automobile and associated industries. The core of the cluster is made up of manufacturing industries, but also includes several service sectors. The periphery of the cluster has less variety, mainly including the transportation equipment and electrical machinery industries. We find that intra-industry externalities that diffuse over a broader area within the cluster help the steady growth of the transportation equipment industry. In the core of the cluster, the diversified interrelated structure also contributes to the growth of the auto-related manufacturing sectors.
