The author explicates some developing aspects in the field of IC industry as suggested areas of future work. The original points of this dissertation are as following: 1. In this dissertation, we got the quality learning curve of China's IC manufacturers by regression. On the base of questionnaire, we later explained the reason of the reverse S type quality learning curve and the tendency of change in quality learning curve. 2. The evolution of technical unit of China's IC industry is calculated in this dissertation. We also explained the reason of technical unit splitting in the way of economic and technology. 3. In this dissertation, we described the environment difference in capital, technology transfer, human resource and market in USA, Japan, Korea, Taiwan and China, and gave some suggestions on the government's role in the development of China's IC industry.. 4. In this dissertation, we established an SD model of China's IC industry, and by using this model, we got some suggestions for future development in China's IC industry.
