The Structural and Spatial Characteristics of the Actor Networks of the Industries for the Elderly: Based on the Social Network Analysis* Yangmi Koo** Abstract Based on the social network analysis(sna), this study examines the structural and spatial characteristics of the actor networks of the manufacturing industries for the elderly. In the field of economic geography, former researches on network have mainly focused on the network governance. However, this study focused on the social network analysis. Centrality indexes are used to analyze the topological structure of actor networks of firms and organizations. In order to investigate the spatial structure of actor networks, not only the regional distribution of actors but also the correlation between centrality index and distance are analyzed. Network matrixes among actors are transformed to network matrixes among regions using block modeling method to reveal the spatial characteristics of the actor networks. In spite of the importance of the Capital Region, networks in the non-capital Region like Chungnam and Pusan were showed high network density. This suggested that some kinds of policy project operating in the non-capital Region had the influence on this network in the initial stage of industry. : actor, network, industries for the elderly, social network analysis, centrality, block modeling POST-DOC (Post-Doc, Korea Research Institute for Human Settlements), yangmi@snu.ac.kr 526
