According to this classification, this project then conduct the following analysis and research. We found that the R&D of 966 sample companies in the past ten years were mostly concentrated in telecommunication and semiconductor. From the research results, we can understand the overall change and growth rate of R&D expenditure in Taiwan in the past ten years, especially the R&D funding has increased in semiconductor industry year by year. Through the research results, we can also see the changes in R&D expenses and net profit growth rates of individual industries over the years. The changing trend of the R&D expenses of individual industries is roughly in line with the changing trend of the overall industry, and both are increasing year by year, while the net profit growth rate has changed significantly.
