홈네트워크 산업지수 개발에 관한 연구

It is difficult to understand and define the home-network industry because the homenetwork industry has various characteristics stemmed from different industries. The purpose of the study is to define the home-network industry and develop the home-network composite industry index for measuring the current state of home-network industry so that we can look inside of evolution process of home-network industry over years. To identify the home-network industry, we investigate four different sectors - infra sector, solution sector, device sector, and service sector - which are relevant to the home-network industry. For each different sectors, the study develope three index of different aspects – index related with managerial performance, index related with market, and the index related with future prospect -. Every index score is standardized between 0 and 100 so that 50 indicates average score. After calculation of three different aspect index for each sectors, the final composite index is computed based on the aggregation of four different individual industries. To aggregate the different industry index, the weighted coefficient is utilized based on the market shares of individual industries comparing with the total market size of home-network industry. The final composite index provides 23.5 in 2005. The composite index value is useful if we investigate these values over time. It is interesting to note that the solution and infra industry has high score of both managerial index and market indicator index. On the contrary, the service and solution industry has high score for future prospect index. The implication is that solution and infra industry have major role of the development of home-network industry at present. However, service and device industry have major role for the development of home-network industry for future. The study has several limitations to overcome. Insufficient historical data makes difficulties to understand the relationship between related industries and to make comprehensive framework of measurement model of home-network industry. However the study is the first trial to measure the current state of home-network industry. And more sophisticated measurement model will be expected in further study with sufficient data over long time horizon. The index is useful to understand the evolution process of home-network industry if we investigate the index over several years. The index can be utilized to make strategic decision making for both government and private company as well.
