博士 / 國立成功大學 / 工業與資訊管理學系碩博士班 / 98 / The size of CRT TV has always been limited by their bulk. However, the introduction of flat plane display TV has led to much larger screens, new rounds of technological innovation, large-scale investment and an increasing share of the consumer market. Moreover, this development has spurred competition for market share between LCD TV and PDP TV. On the basis of diffusion model and the premise of population growth on variable market potential, this study establishes a model of forecast for technology replacement. This proposed model is further applied to investigate the replacement of CRT and LCD TV with empirical analysis. This study further intends to investigate the dynamic competitive relationship between PDP and LCD TV by means of the quarterly shipment of TV. The Lotka-Volterra competition diffusion model has been adopted to conduct the empirical analysis, with the Lyapunov function used to carry out equilibrium and stability analysis.
Those who purchase TVs for the first time are apt to be more attractive to LCD TV than CRT TV. As for those who have already owned a CRT TV, the intention is not strong enough to allure them to replace current CRT TV with a new LCD TV. In the competitive relationship we can regard the LCD TV as a prey and the PDP TV as the predator. With respect to the equilibrium and stability analysis, PDP TV will not disappear from the market, but will instead reach stable equilibrium with LCD TV.
