The aim of this study is to analyze changes in industrial networks from a smart city perspective. Smart city industries are classified into ITM, ITS, and KS based on literature review and smart-x cases. These industries use technologies that enable rational industries to exhibit intelligence, thereby allowing the industries see, hear, smell, and feel. The changes in industrial networks are primarily centered on in-out degree centrality, closeness centrality, betweenness centrality, and industrial clusters. In this study, a social network analysis is conducted using input-output tables published by the Bank of Korea from 1960 to 2015, and the GDP deflator is applied for year-over-year analysis.
The key findings are as follows: First, the industrial network structure results in an increase in density. In the early stage, smart city industries are less influential owing to their smaller node size compared with those of classic industries, as well as their owing to their locations outside the range of networks. However, as time progresses, the number of nodes in smart industries increased in IT manufacturing and knowledge industries, and smart city industries are operated closer to network centers. Second, the centrality of smart city industries, in-out degree centrality, closeness centrality, and betweenness centrality result in network changes in IT manufacturing and knowledge industries, thereby rendering the independent development of smart city industries difficult. This implies that the structure of smart industries is affected by external industries. Third, although the number of industrial clusters has increased, the number of smart city industrial clusters have not. In addition, connections among smart city industries are insufficient. Changes have occurred in smart city industrial networks of IT manufacturing, IT service, and knowledge industries, albeit at an insignificant level. In conclusion, IT manufacturing and knowledge industries are the primary industries that will either promote or hinder the growth of the overall structure of smart city industries.
