Abstract Previous studies generally indicate that increasing investment in research and development (R&D) positively affects economic growth. However, there exists limited discussion on the efficient ratio of R&D investment for basic, applied, and development research. Therefore, this study conducted an empirical analysis of the efficient ratio of R&D investment based on national data in Korea. In addition to different R&D activities, this study estimated the optimal ratio of financial source types according to public and private R&D. The results of this study indicate that the investment ratio in R&D activities and financial source types should be adjusted.

一种新的效率比方法：以韩国研发投资为例

摘要 以往的研究普遍表明，增加对研发（R&D）的投资会对经济增长产生积极影响。然而，关于基础研究、应用研究和开发研究的 R&D 投资有效率的讨论有限。因此，本研究基于韩国国家数据对R&D投资效率进行了实证分析。除了不同的研发活动外，本研究还根据公共和私人研发活动估计了资金来源类型的最佳比例。本研究结果表明，应调整研发活动的投资比例和资金来源类型。
