제조 벤처기업의 혁신에서 R&D 보조금의 투입 및 행동 부가성(Additionality) 효과: 대기업 매출비중의 조절효과를 중심으로

This study analyzed the additionality effect of government R&D subsidy on manufacturing venture firms and the moderating effect of the dependence on large firms on the relationship between R&D subsidy and inputs and behavioural additionality. The analysis using the survey data of venture firms from 2011 to 2016 confirmed that venture firms received government R&D subsidies significantly increased the ratio of R&D expenses to sales on average compared to those that did not receive R&D subsidy. In addition, venture firms that received government R&D subsidies significantly increased the ratio of R&D staffs with advanced degrees and the scope of partnerships with external organizations compared to those that did not receive government R&D subsidies. In other words, R&D subsidies have significant input and behavioural additionality effects so that R&D investment, R&D staffs with advanced degrees, and the range of partnerships with external organizations of venture firms increases more than those when they do not receive R&D subsidies. On the other hand, this study confirmed that the sales dependence ratio of venture firms on large firms negatively moderated the relationship between R&D subsidy and input and behavioural additionality. The results suggest that the government R&D subsidy for venture firms with an excessive level of dependence on large firms may become invalid because the positive effects of R&D subsidy on the venture performance are reduced as the level of dependence on large enterprises become higher.
