  • Indigenous technological development and import of foreign technologies are two major sources of industrial innovation in Korea. This paper mainly deals with the analysis of the relationship between the two sources, employing the Tobit method. The estimation of the effects of those two sources on the firms' sales growth is also performed, including other exogenous variables such as fixed capital formation and the amount of exports, etc. in the model. Technological import is shown to be complimentary rather than substitute for or competitive with R&D in the Korean industries during 1990. This is understandable because R&D may be conducted to absorb and adapt the advanced imported technologies as well as to further more innovative technological development. Fixed capital formation is positively correlated with technology import, but negatively correlated with R&D. Technology importation seems to have contributed much more than R&D to the sales increase in the Korean industries.

  • 본 연구는 치악산국립공원 구룡 오토캠핑장 이용객을 대상으로 설문조사를 실시하여(N =165), 누가 그리고 왜 오토캠핑을 휴양활동으로 선택하였는지 분석하였다. 설문조사 결과 오토캠핑장 주이용객은 교육 수준(전문대졸 이상 88%)과 소득 수준(가구 총소득 3,000만 원 이상 87%)이 높은 30~40대(85%)의 직장인(60%)이었다. 또한 오토캠핑 이용객은 가족 단위 이용객(82%)이 대부분이었고 오토캠핑장을 년 10회 이상 이용한다는 응답자 비율이 24%에 달해 오토캠핑이 주요 여가 활동인 경우도 많았다. 5년 이상 오토캠핑 경력이 있는 응답자는 18%에 불과해 오토캠핑은 최근 수요가 증가하고 있는 휴양 활동이라는 것을 알 수 있었다. 오토캠핑의 19개 장점에 대한 응답자들의 동의수준 데이터를 요인분석으로 분석한 결과, '자연접촉으로 기분전환(요인 1)', '새로움과 성취감(요인 2)', '편리성(요인 3)', '즐거움(즐길거리)(요인 4)'의 4가지 오토캠핑 선택 요인을 추출하였다. 4가지 오토캠핑 선택 요인이 오토캠핑장 이용 만족도(연간 오토캠핑장 방문 횟수)에 미치는 영향을 토빗(Tobit) 회귀분석으로 분석한 결과 '자연접촉으로 기본전환'의 영향이 가장 크고, '편리함', '즐거움' 순으로 영향을 주었지만 '즐거움'은 오토캠핑장 이용 만족도에 통계적으로 유의미한 영향을 주지 않았다. 이는 오토캠핑장 설계 운영시 편의시설이나 놀이시설을 늘리기 보다는 주변의 자연을 훼손하지 않고 유지하도록 할 필요가 있음을 시사해 주는 결과이다.
