Abstract: In this paper, we research the influence factors of R&D input in late-development countries base on the data of 86 late-development countries in the period 2003-2012 using the panel data fixed effects model. The regression result is that the number of researchers and the financial development has a significant positive influence on the R&D input in late-development countries, while manufacturing imports and FDI inflows has a significant negative influence on the R&D input in late-development countries. Further study found that the intellectual property protection level has a significant positive moderating effect for the relationship between financial development, or manufacturing import and R&D input. It is said that the higher level of the intellectual property protection in late-development countries, the financial development can promote more R&D input, and the manufacturing import restrain more R&D input. Future research could be further from the dynamic perspective, not only to investigate the factors that influence the R&D input but analyze its R&D performance.

摘要： 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。
