碩士 === 朝陽科技大學 === 財務金融系碩士班 === 97 === The output value scale of photoelectric industry has broken through two trillion NTD in 2007, and presents the trend of growing up year by year. The supply chain of every group in photoelectric industry has formed by their group effect. The demand and supply will reduce after depression of economy in 2008. It is important to strengthen technology and competition. There is less document focusing on productivity of Taiwanese Optoelectronic Industry by panel data and Cobb-Douglas production function and parameter of R&D spillover. So, this research regards Taiwanese photoelectric industry to explore the effect of R&D expenditure and R&D spillover on productivity. This research built firm-level panel data of Taiwanese photoelectric industry from 2000 to 2008 and use Griliches (1979) extended Cobb-Douglas production function for empirical structure. To verify which fixed effect or random effect of panel data is the best empirical module. The whole samples will be divided into several groups and verify the difference of productivity at every group. The empirical result of whole samples will fit fix effect for best module. R&D expenditure and R&D spillover are key parameter for productivity of Taiwanese photoelectric industry. At sub samples, the best module of optical information is fix effect and the effect of R&D expenditure and R&D spillover will affect productivity. The effect of optical display and optical component groups for fix effect is R&D expenditure and R&D spillover. The result will be the same as other groups is fix effect and the same key parameter. Finial, R&D expenditure and R&D spillover are effective to affect productivity of Taiwanese photoelectric industry.
