| Outline of Final Research Achievements |
Based on the international trade and economic growth models with ICT, we analyze the process of income inequality being caused by the development of ICT. The results are as follows.
(1) Regarding international trade (two countries model), the development of ICT increases wage ratio of skilled workers for both countries, and decreases of unskilled workers for those countries. Furthermore it increases income inequality in big country and reduces the inequality in small one. (2) Regarding two-sector model with ICT good production, when some relationship between parameters of intensities in both production sectors holds ,the high intensity of ICT good as input enhances economic growth rate. Furthermore the most important thing as economic policy is to enhance the aforementioned intensity, so that the difference of the degree of ICT intensity causes the economic difference.
