The production of abalone seed has grown and been specialized since the 2000s with the growth of the abalone farming industry. Despite the increase in the production of abalone seeds, the sales volume of abalone seeds remained flat and competition among producers increased. This paper will analyze the management efficiency of abalone seed production fishery to diagnose the management status and improve the abalone seed production efficiency. In addition, this study is the result of the basic research on the abalone seed industry and it is meaningful to prepare a platform for further research since the management status survey and the management efficiency survey of abalone seed production fishery have not been conducted until now. The data on the farmed fish prices of abalone seeds were collected from surveys of sample fish as part of the fish seed observation project conducted by the Fisheries Outlook Center (FOC) of Korea Maritime and Fisheries Development Institute (KMI). Management efficiency analysis utilizes DEA (Data Envelopment Analysis) model. The DEA model was analyzed by classifying into CCR (Super-CCR), BCC, and SBM (Super-SBM) models according to the assumptions taking into account the characteristics of the industry. The slack considered in the SBM model was judged as possible decreases in input variables and increase in output variables. The average efficiency from the CCR model was analyzed to be 69%. The BCC model was classified into input and output orientations, and the average efficiency was 79% and 75%, respectively. There were seven production fisheries with an SE value of 1 or more, which remained unchanged in terms of size and could be benchmarked. The average efficiency of the SBM model was 59% for CRS and 66% for VRS. Under the VRS assumptions, the variable increase/decrease efficiency analysis shows that labor costs can be reduced by 37.3%, facility capacity by 18.8%, and operating costs by 8.5%. In order to improve management efficiency, Wando needs to reduce labor and management costs. In Jindo region, sales increase as well as labor cost reduction is urgent. In other regions, reduced facilities and increased sales are recommended.

스마트폰 시장에서 글로벌공급망(GSCM: global supply chain management)과의 국제 전략적 제휴(ISA: international strategic alliances)를 통한 신제품 공개(NPP: new product preannouncement)는 기업의 생존과 경쟁우위를 결정하는 핵심요인이다. 이에 본 연구는 애플의 아이폰(iPhone)과 경쟁하기 위해 지속해서 신제품을 공개하고 있는 삼성전자의 갤럭시 노트시리즈(Galaxy Note series)를 중심으로 글로벌공급망을 탐색제휴(exploration alliance)와 활용제휴(exploitation alliance)로 구분하여 사건연구(event study)와 횡단면 회귀분석을 시행하였다. 연구결과는 탐색제휴를 통한 신기술과 활용제휴를 통한 기존기술에 관한 정보는 모두 갤럭시 노트의 신제품 공개 하루 전(-1)에 해당 부품공급업체(vendors)의 단기성과에 긍정적인 영향을 미치고 있는 것을 확인하였다. 주목할 점은 신제품 공개를 위해 적용한 신기술 정보가 기존기술 정보보다 초과수익률이 더 높은 것으로 밝혀졌다. 이는 신기술을 제공한 기업일수록 기존기술을 제공한 기업보다 혁신역량이 높고 여유자원이 풍부하여 시장에서는 이를 긍정적인 신호로 인식하고 있는 것으로 밝혀졌다. 또한 이 연구는 탐색제휴로 확보한 신기술은 혁신역량과의 상호작용을 통해 신제품 공개에 도움을 주는 핵심요인으로 스마트폰 시장에서 생존 여부를 결정지을 수 있는 중요한 변수임을 실증분석을 통하여 검증하였다는 점에서 의미를 가진다.
