摘要
基于包含水平创新的内生增长模型,构建了一个同时包含基础研究和应用研究的R\&D驱动经济增长模型,并考察了分散经济与社会计划者经济下的R\&D资源配置问题.研究发现,当经济收敛于平衡增长路径上时,基础研究和应用研究的生产效率越高,经济增长率越高;分散经济框架下的R\&D规模比社会计划者经济框架下的R\&D 规模更小;分散经济下基础研究占R\&D支出的比例比社会计划者经济更低.政策含义是,政府可以通过对R\&D予以补贴,尤其是对基础研究给予补贴,从而使分散经济下的R\&D 规模和R\&D结构实现社会最优.
Abstract
Based on the endogenos growth model with horizontal innoation, we propose an R&D-driven growth model with both basic research and applied research,
and discuss both the growth rate and the R&D allocation in the decentralized economy and the social planner economy. It is found that when the economy converges to the balanced growth path, the growth rate in the decentralized economy is equal to that of the social planner economy. However, the ratio of the R&D in GDP and the ratio of the basic research in R&D expenditure in the decentralized economy are less than that of the social planner economy. The policy implication of these results is that, thegovernment could subsidy the R&D investment and the basic research, and so that the decentralized economy could reach the optimal stage.
