Abstract

Diffusion model is popular research topic in marketing and economy particularly for the areas of model specification and market size forecasting. In particular, Bass model can explain Roger's innovation diffusion and product life cycle through easy mathematical representation and hence the model has been widely used for the explanation of adopting innovative new products and technologies. Nonetheless, there're only a couple of pioneering researches about semiconductor market, using diffusion models. Consequently, we'd utilise NLS approach diffusion model to estimate the market potential of MOSFET, major switching device for power management of system, and explain the process to industry stakeholders and policy makers for delivery of managerial implication with pragmatic purpose.

확산모형은 시장의 예측이나 그 방법론의 연구를 위해 마케팅에서 광범위하게 다뤄졌을 뿐 아니라, 경제학에서도 다양하게 활용되어 왔다. 특히 Bass 모형은 Rogers의 혁신확산 및 수명주기이론을 간단한 수리적 모형으로 표현할 수 있기에 혁신적 신제품의 채택과 확산을 설명하는데 널리 활용되었다. 그럼에도 불구, 확산모형은 '산업의 쌀' 이라 일컬어지는 반도체의 수요예측에 일부 선도적 연구를 제외하고는 활용된 바 없다. 이에 Bass 모형에서 진일보한 비선형회귀 접근법 확산모형을 활용, 전력반도체 중 전기전자기구의 필수 스위치로 채택되는 MOSFET의 수요를 추정하여 수명주기를 예측하고 그 과정을 설명함으로써 산업관계자는 물론 반도체와 전기전자산업 정책입안자에게 중요한 시사점을 전달하고자 한다.
