This study aims at investigating the effects of Government R&D subsidies. We analyse the effects of inputs and behavioral additionality on the output additionality. We also measure the moderate effects of the experiences of benefiting from government R&D on the relationship between inputs and behavioral additionality and the output additionality. We conducted a structured questionnaire on the companies who have participated in promotion program of the Korea Innovation Cluster. 126 responses were collected and alnalysed using the OLS technique. Empirical results show that the relationship between input/behavioral additionality (management, follow-up, cognitive capacity) and output additionality had positive effect. The moderating effects of experiences of R&D subsidy on the relationship between input additionality and output additionality and the relationship between cognitive additionality and the output additionality appear to be statistically significant.

선박운항 시뮬레이터는 다수의 하드웨어 및 소프트웨어, 데이터 요소들로 구성되어 있어, 시스템 설계가 매우 난해하며 활용 목적에 맞춰 신중하게 설계하지 않으면 활용도가 떨어지거나 가성비가 나빠진다. 범용성을 요구하지 않는 특정 목적 선박운항 시뮬레이터의 경우, 구성 요소 별 기여도 및 자원 투입 비율을 검토하여 설계에 반영하도록 하고, 필수 기능보다 부가 기능에 많은 자원이 투입되지 않도록 주의해야 한다. 본 발표에서는 특정 목적 선박운항 시뮬레이터 개발 사례를 분석해 보고, 사례별 보다 적합한 설계 방향을 도출해 보았다.

This paper attempts to investigate how and why the additionality effects occur in the case when a firm receives government subsidy as opposed to counterfactual situation. To demonstrate this, we selected 12 SMEs(small and medium enterprises) firms in Daejeon area and have conducted multiple case studies. In order to analyse the multiple cases of firms, we classified firms innovative activities into three stages which are composed of input, behaviour and output stages and related various factors. Furthermore, we investigated the differences according to types of firms and stages of firm growth. Empirical results show that various input, behaviour and output additionality effects exist when firms receive public subsidies. Compared to companies in the growth and mature stages, startup phase companies depend on government subsidy extensively and they use public subsidies strategically to develop new product and to change their strategic direction. The attitude of firms to use government subsidies is different according to their types and stage of growth as well.
