DEA 모형의 종류는 어떻게 나눌 수 있는가? | DEA(Data Envelopment Analysis) 모형의 종류는 크게 다음과 같이 나눌 수 있다. 먼저 규모수익에 대한 가정에 따라 불변규모수익(CRS: Constant Return to Scale)을 가정하는 CCR 모형과 가변규모수익(VRS: Variable Return to Scale)을 가정하는 BCC 모형으로 나눌 수 있다. 또한 지향성에 따라 투입요소에 초점을 두는 투입기준(Input oriented) 모형과 산출요소에 초점을 두는 산출기준(Output oriented)모형으로 나눌 수 있다[24]. | |
특허지표들은 무엇으로 분류할 수 있는가? | 특허지표는 특허분석의 기본이 되는 지표이다. 선행연구에 의하면 특허지표들은 1) 특허 수, 2) 국제지수, 3) 피인용수 및 4) 청구항으로 분류할 수 있다.1) 특허 수는 출원특허 수, 공개특허 수 및 등록특허 수로 분류할 수 있으며, 기업의 특허 수를 추적하여 기업의 연구·개발 활동의 발전과 기술 개발 동향을 관찰 할 수 있다. | |
