홈페이지논문 초록 (Abstract)
n this study, we explore the long-term demand forecasting of high-price medical equipments based on logistic and Bass diffusion model. We analyze the specific pattern of each equipment’s diffusion curve by interpreting the parameter estimates of Bass diffusion model. Our findings are that (1) Ultrasonic imaging system, CT are in the stage of maturity and so, the future demands of them are not too large. (2) Medical image processing unit is between growth stage and maturity stage and so, the demand is expected to increase considerably for two or three years. (3) MRI is in the stage of take-off and Mammmography X-ray system is in the stage of maturity but, estimates of the potential number of adopters based on logistic model is considerably different to that based on Bass diffusion model. It means that additional data for these two equipments should be collected and analyzed to obtain the reliable estimates of their demands. (4) Medical image processing unit have the largest q value. It means that the word-of-mouth effect is important in the diffusion of this equipment. (5) For MRI and Ultrasonic system, q/p values have the relatively large value. It means that collective power has an important role in adopting these two equipments.
