중소기업의 성장에 미치는 정부 R&D 지원의 효과:기업연령을 중심으로

This study analyzed the effects of government R&D support on small and medium-sized enterprises(SMEs) under the Industrial Technology Innovation Program, categorized by firm age. Using Propensity Score Matching(PSM) and Difference-in-Differences(DID) methods, it was determined that R&D support significantly influenced sales growth between the second and fourth years after receiving support". The research confirmed that while government R&D assistance fosters growth across all developmental stages of companies, the effects vary depending on the specific growth stage. Notably, in mature companies, increased R&D funding significantly enhanced sales growth rates, with the effect becoming more pronounced over time. Conversely, in early-stage companies, as the amount of support increased, the increment in sales growth rates gradually diminished, which were relatively lower compared to those of companies at other stages. These findings suggest that government R&D policies should be strategically designed to consider both the growth stage of companies and the specific attributes of the government R&D programs providing the support, specifically, support for early-stage companies should encompass not only financial assistance but also a comprehensive approach, including aid for new market entry and network expansion.
