文章基于2003-2012年世界86个后发国家的研发数据,运用面板数据的固定效应模型,对后发国家研发投入的影响因素进行研究分析。通过检验发现:R&D研究员数、金融发展对后发国家研发投入具有显著的正向影响,而制造业进口和FDI净流入对后发国家研发投入具有显著的负向影响。进一步研究显示,知识产权保护程度对金融发展、制造业进口与后发国家研发投入的关系具有明显的正向调节作用,即知识保护程度越高的后发国家,金融发展越能促进研发投入,制造业进口则越抑制研发投入。未来研究可以进一步从动态视角,不仅探讨影响研发投入的因素,还要分析其后续的研发绩效。
Based on the R & D data of 86 developed countries in the world from 2003 to 2012, the paper uses the fixed effect model of panel data to analyze the influencing factors of R & D investment in developed countries. It is found through inspection that: R & D researchers and financial development have a significant positive impact on R & D investment in developed countries while manufacturing imports and FDI inflow have a significant negative impact on R & D investment in developed countries. Further research shows that the degree of protection of intellectual property has a significant positive effect on the relationship between financial development, manufacturing import and post-development R & D investment. That is, the higher the degree of knowledge protection, the more developed countries, the more financial development can promote R & D investment, The more manufacturing imports inhibit research and development investment. Future research can be further from a dynamic perspective, not only to explore the factors that affect R & D investment, but also to analyze its follow-up R & D performance.
