政府R&D支出对企业R&D支出的影响——基于省际数据的实证分析

技术进步是经济长期增长的源泉,而研究与发展活动是整个科技活动的核心。政府从事R&D活动有可能对企业的研发行为产生两种不同的影响:替代效应和互补效应。基于中国31个省份面板数据的实证研究发现,整体上而言,目前政府R&D支出与企业R&D支出存在互补关系,政府R&D支出能够诱导企业R&D支出。但这种诱导效应随着政府R&D投入强度的提高而递减,这表明随着政府R&D投入强度的提高,挤出效应越来越明显。

The Effect of Governmental R&D Expenditure on Corporate Expenditure: Empirical Analysis Based on Provincial Data

Technological progress is the source of long-term economic growth, and research and development activities are the core activities of science and technology. The government engaged in R&D activity may produce two different effects for the corporate R & D behavior: crowding out effect and complementary effect. The empirical study based on Chinese 31 Provinces panel data found that, on the whole, there are complementary relationships between the governmental R&D expenditure and the corporate R&D spending, and governmental R&D spending can induce corporate R&D expenditure. But this inductive effect decreases with the R&D input intensity increasing, suggesting that as the governmental R&D investment intensity increases, crowding-out effect is more obvious.
