本文基于中观和微观视角,运用我国战略性新兴产业微观企业数据,研究产业集中度、企业市场势力对研发创新的影响。结果表明,在产业整体、政策后、低资本密集度、东部地区和非国有企业的回归中,产业集中度和企业市场势力与研发创新分别呈“倒U”型和“U”型关系。此外,过高的固定资产比率不利于研发创新,而净资产收益率和人力资本的提升对创新有积极影响。

In addition, too high a fixed asset ratio is not conducive to R & D innovation, while the return on net assets and human capital increase have a positive impact on innovation.
