The importance of the telecommunication industry is well recognized. However, few studies provide a systematic approach to measuring the competitiveness of this industry. In this paper, competitiveness and globalization indices are developed within the framework of the generalized double diamond model. These measures are calculated from the survey data of the evaluation of Korea`s telecommunication industry by foreign investors in Korea. Policy makers will find these two indices useful in formulating effective policies to enhance the competitiveness of the telecommunication industry.
