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

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

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。

Technological progress is the source of long-term economic growth, and research and development activities are the core activities of sci ence 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 invest- ment intensity increases, crowding-out effect is more obvious.
