摘　　要： 目前关于产品种类扩大型和熊彼特质量改进型的技术创新内生增长模型均较完善,但缺乏同时纳入两类技术变革的内生增长模型。本文构建了包含两类技术创新的内生增长模型,综合分析了技术进步导致经济增长的内在机制,并利用全要素生产率核算方法进行了测算。测算发现在1995年至2009年期间政府有意识的技术研发投入对中国经济增长的贡献率上升了12个百分点,但与发达国家相比仍有较大差距,需要政府进一步加大研发投入力度,同时加大科技成果转化为经济效益的强度。 Since the neoclassical thesis, people have recognized that scientific and technology progress is the source of economic growth. This paper builds an endogenous growth model with two kinds of innovations, and provides a full explanation to the internal mechanism of innovation driven economic growth. The model shows that both innovation of expanding the quantity of products and innovation of improving the quality of products are the source of long - run economic growth. And results of empirical analysis indicate that the origi- nal extensive economic growth mode has changed in China. Compared with developed countries, however, there is still a wide gap. The government need to further increase investment and efficiency.
