The Impact of Governmental R&D Subsidies on Enterprise R&D Investments——An Empirical Analysis Based on the Panel Data of Industrial Firms Above Designated Size in Zhejiang Province

政府对R&D活动的投资将产生双重效应:杠杆效应和挤出效应。现阶段,浙江财政R&D投入对民间R&D投入的激励效应如何?政府资助率为多高时杠杆效应最佳?文章运用浙江省规模以上工业企业2003年行业截面数据和2006-2008年行业面板数据,通过计量分析方法和模型,就政府R&D资助对企业R&D投入的影响进行实证检验。结果表明,在样本期内政府科技投入对企业R&D支出具有明显的促进作用,轻工业企业的政府最佳资助率要高于重工业企业,对轻工业的R&D资助产生的杠杆效应大于重工业企业。
