R&D私人投资与公共投资的互补性：一个动态面板数据分析
Complementarity between private and public investment in R&D: A Dynamic Panel Data analysis
摘要：
本文考察了R&D中私人和公共投资之间的关系，同时考虑了补贴和税收等几种工具政策的影响。我们设计了一个新的视角来解释知识溢出和R& D合作对增长的贡献。本文提出了一个考虑R&D投资内生效应的异质动态面板数据模型。我们还区分了估计的长期和短期结果。我们基于1992-2004年期间23个国家的样本的结果表明，公共和私人投资在R&D是互补的。通过建立内生增长模型，估计表明，公共和私人R&D依赖于东道国的人力资本投资。结果表明，外商直接投资是一个更显着的溢出渠道比进口。
英文摘要：
This paper investigates the relationship between private and public investment in R&D, while taking into account the effect of several instruments policies such as subsidies and taxes. We design a new look of knowledge spillovers and R&D cooperation to explain the contribution of public and private R&D on growth. We propose a heterogeneous dynamic panel data model to consider the endogenous effect of R&D investment. We also distinguish between the estimated long and short run results. Our results based on a sample of 23 countries over the period 1992-2004 indicate that both public and private investments in R&D are complementary. By establishing an endogenous growth model, the estimates indicate that public and private R&D depends on the host country's human capital investment. Results indicate that foreign direct investment is a more significant spillover channel than imports.
