Comparative Research of Competitiveness and Influence Factors of Computer and Information Service Trade of South Korea, China and Japan

The paper chooses four trade competitiveness assessment indices to compare the international competitiveness of Computer and Information Service(C&IS) trade between South Korea, China and Japan. The results show that the competitiveness of China is the strongest, Japan secondary and Korea the weakest among the three countries. However, the competitiveness of Korea can be promoted the most quickly and it has exceeded Japan according to TC and NXRCA indices. Meanwhile, there was still a huge gap between the three countries and the two world strong countries?India and Ireland. The main findings of empirical research on influencing factors show that domestic market demand and trade opening degree are the two most important factors influencing the competitiveness of three-country C&IS trade. At the same time, improving the utilization of C&IS and realizing good interaction of C&IS trade and electronic information, communication and other relevant and auxiliary industries can also contribute to the competitiveness improvement.
