Abstract: This study examines how internal capital markets (ICMs) within business groups affect the financing of research and development (R&D) investments, focusing on Korean chaebols. We find that, on average, chaebol-affiliated firms exhibit lower R&D investment – cash flow sensitivity than standalone firms do. We also find that an affiliated firm’s R&D expenditure is significantly positively associated with the net amount of equity capital received from other affiliates but not significantly related to its own cash flow. These findings indicate that ICMs effectively mitigate affiliated firms’ R&D financing constraints. We further find that this financing constraint mitigation is more pronounced during financial crises and for high-tech firms. Finally, we find that, for chaebols, greater ICM effectiveness leads to better innovative performance. Overall, our study highlights the importance of ICMs for promoting corporate innovation via the reduction of R&D financing constraints.
