Static and Dynamic Network Analysis of Internal Transaction between Chaebol Affiliates

The role of Korean chaebols has been important for the economic growth of South Korea, but there exist disputes regarding the impact of chaebols on Korean economy. Recently, internal transactions between chaebol affiliates have attracted a fair amount of attention. In this paper, social network analysis (SNA) methods have been applied to analyze the static and dynamic aspects of internal transaction networks of the top five Korean chaebols. The results showed the internal transactions of the top five Korean chaebol have been strengthened during 2009 and 2015. In particular, outbound centralization increased for the chaebols, which means centralization became stronger from the seller’s standpoint. Also, the benefit of internal transaction has been selectively given to specific areas such as System Integration(SI), MRO, and marketing. This paper shows that SNA can be used in the empirical study of the internal transactions of Korean conglomerates.

Success Factors of Game Products by Using a Diffusion Model and Cluster Analysis

As the global game market has been more competitive, it has been important to analyze success factors of game products. In this paper, we applied a Bass Diffusion Model and Clustering Analysis to identify the success factors of games based on data from Steam, an international game platform. By using a diffusion model, we first categorize game products into two groups : successful and unsuccessful games. Then, each group has been analyzed by using clustering analysis based on product features such as genres, price, and minimum system requirements. As a result, success factors of a game have been identified. The result shows that customers in game industry appreciate sophisticated contents. Unlike many other industries, price is not considered as a key success factor in the game industry. Expecially, advanced independent video games (commonly referred to as indie games) with killer contents show competitiveness in the market.
