摘　　要：基于拓展的以R&D为基础的内生增长模型,分析R&D资本在创新和模仿中的最优分配,结果表明,技术差距、人均物质资本、模仿与创新的相对效率等因素决定了R&D资本的最优分配,进而决定了最优的技术进步。投入创新中的R&D资本与技术差距、人均物质资本、模仿与创新的相对效率成反比,而对于模仿而言则相反。因此,为了实现技术赶超,技术后发国应当充分利用后发优势,加大研发投入,努力提高研发效率。Based on the R＆D-based endogenous growth model, the paper analyzes the optimal allocation of R＆D resources between innovation and imitation, which concludes that technological gap, per-capita physical capital, and the efficiency in imitation relative to innovation determine the optimal allocation and the optimal technology progress. The capital input in innovation is negatively related to these factors, while that in imitation is positively related to them. Therefore, in order to get a more rapid progress in technology, the developing countries should fully use the technology-behind advantage, increase the R＆D input, and improve the efficiency in R＆D.
