西方文献普遍认为R&D活动的“市场失灵”是政府R&D资助存在的根本原因。随着近3年来的发展,我国上市公司已较为普遍地接受了政府R&D资助,政府R&D资助有效性问题等关系到国家干预在经济中发挥作用的评估研究,亟待提供评价的经验证据。本文以中国证券市场2003至2005年间的上市公司为样本,对政府R&D资助与上市公司R&D支出之间的关系进行了实证检验。本文关注的核心问题是政府R&D资助是刺激还是挤出了企业R&D投资。实证发现,政府R&D资助刺激了企业R&D支出。
This paper analyzes the effects of public R&D subsidies on innovation expenditure of Chinese listed companies. The key issue is whether public R&D stimulates or simply crowds out private R&D investment. Cross sectional data at the firm level are used to estimate the effect of subsidization. The empirical result shows that public funding increases firms' R&D expenditure. So the hypothesis of crowding - out effects between public and private R&D funding can be rejected.
