Abstract

Albeit numerous endeavors in matching names and surveying inventors, inventor-level studies of patent data have been scarce because unique inventors can not be identified across patents. Using the Korean patent data with inventor IDs, birth year, and gender available, we construct unique inventor-level panel data. As the first undertaking with our data, we investigate the age profile of patent productivity among inventors. We find an inverted U-shaped profile with the peak at age 31. We also find an increasing productivity for younger cohorts of inventors. These findings are robust after we control for the calendar year effects and the quality of patents.

1980년대 이후 특허 데이터를 이용한 많은 연구가 있었지만, 특허문서에 나온 기술 개발자의 정보를 이용한 연구는 큰 진전을 이루지 못하였다. 이는 해외 모든 국가의 경우 특허에 기재된 개발자의 이름만으로는 동일인 파악이 어렵기 때문이다. 한국 특허 데이터에 포함된 개발자의 식별번호, 생년, 그리고 성별 정보를 이용하여, 본 연구는 생애주기에서 개발자의 기술개발 생산성이 어떻게 변하는지, 세대별로 생산성의 향상이 있었는지 분석하였다. 앞으로 이 개발자 패널데이터를 이용하여 기술개발의 중요한 요소인 기술인력에 관한 연구가 크게 진전되리라고 기대한다.
