摘　　要：文章在拓展的模仿与创新的一般均衡模型中比较分析了人力资本约束下改善研发资源供给和研发激励两类科技政策的效应。研究表明,在有限人力资本约束下,研发激励政策使均衡时的创新率和模仿率此消彼涨,对经济增长的效应并不明显;但人力资本、特别是创新型人力资本供给增加能有效促进技术进步和经济增长。基于中国的经验分析表明,研发激励政策对技术创新和经济增长的长期效应要远远小于高质人力资本供给增加的长期效应。其政策含义是:促进技术进步的政策应当优先考虑改善核心研发资源的供给,研发激励政策应当在核心研发资源供给富有弹性的条件下进行。This paper provides a general equilibrium model of economic growth with innovation and imitation to compare the effects of R&D stimulating policies and R&D resources supply improving policy. The analysis suggests that, under the constraint of human capital, R&D stimulating policies cannot promote economic growth effectively as these policies increase one but decrease the other of innovation and imitation at the equilibrium state. In contrast,a bigger stock of human capital, especially innovative human capital, always means a faster growth rate. Empirical analysis on China suggests that improvement in the supply of innovative human capital is more favorable compared with demand- based R&D policy to economic development and technological progress. The policy implication is obvious: the policy of improvement in the supply of innovative human capital should be preferred to promote technological progress,and R&D stimulating policies should be implemented on the condition that the supply of innovative human capital is elastic.
