摘　　要：科研投入没有提升全要素生产率(TFP)并非中国特有现象。本文构建了包含异质性创新的多部门复合增长模型,利用中国现实经济数据和数值模拟方法发现,尽管基础研究投入增加会直接提高基础研究部门生产率,对TFP产生积极影响,但由于高技术劳动力资源从应用研究部门转向基础研究部门,投向应用研究的金融资本回报率降低,会对TFP产生更大的消极影响。在当前的基础研究投入水平下,基础研究投入的经济增长效应被抵消,经济整体TFP增速呈现下降趋势。然而,基础研究投入增强在长期具有提高福利水平的效应。The failure of research inputs to raise total factor productivity(TFP)is not a China⁃specific phenomenon.This paper constructs a multisectoral compound growth model that includes heterogeneous innovation.It uses China's real economic data and numerical simulation methods and finds that although an increase in basic research inputs directly raises the productivity of the basic research sector and positively affects TFP,due to the shift of high⁃skilled labor resources from the applied research sector to the basic research sector,the return rate of financial capital invested in applied research decreases,which has a greater negative impact on TFP.At the cur⁃rent level of basic research inputs,the economic growth effect of basic research is offset,leading to a downward trend in the economy's overall TFP growth rate.However,increased basic research inputs have welfare⁃enhancing effects in the long run.
