본 연구는 우리나라 기술혁신역량증대에 관련된 기술혁신변동성에 대한 실증연구를 목적으로 수행되었다. 본 연구에 대한 실증분석결과를 살펴볼 때, 우리나라 기술혁신변동성에 대한 몇 가지 특징을 제시할 수 있다. 첫째, 우리나라 기술혁신변동성은 최근에 크게 낮아졌으며, 그 원인으로 특정한 산업부문의 기술혁신변동성이 낮아졌기 때문이다. 둘째, 우리나라 기술혁신변동성은 공통요인과 비 공통요인으로 구분하여 분석한 결과는 공통요인에 의한 변동성과 공통요인을 제거한 변동성과 차이는 낮게 나타났다. 이러한 분석결과는 입상가설(Granular Hypothesis)을 뒷받침한다고 볼 수 있다. 따라서 우리나라 기술혁신변동성을 높이기 위한 단기적 정책방향은 기술혁신핵심부문의 전략적 관리와 기술혁신공통성을 증대시킬 수 있는 정책적 고려가 요구된다. 그러나 장기적으로 바람직한 산업구조의 조정과 건전한 기업구조를 갖추기 위한 정책적 노력이 요구된다.
