Abstract: Basic scientific research, as the main way of knowledge production, has been aroused worldwide attention in background of knowledge economy. In this paper, we develop an economic growth model which devides knowledge into basic scientific knowledge and technical application knowledge based on the nature of knowledge and endogenous growth theory. It is used to understand the determinants of different types of knowledge accumulation and the impact to economic growth. We draw one conclusion: the efficiency of basic knowledge into applied technologies will have an impact on the path of economic growth. When economy is in balance growth path, the basic knowledge and the ability of conversion will be conducive to economic growth. The empirical analysis supports the main idea by using the relevant panel data about basic research input from 2004 to 2015.

摘要： 知识经济下基础知识对技术进步和经济增长的影响效应研究一直备受关注。本文将知识分为基础科学知识和应用技术，并结合内生增长理论，构建一个包含基础知识生产的模型，用来分析基础知识及其转化为应用技术的效率对经济增长的影响。研究结果表明:当经济处于平衡增长路径，基础知识及其转化为应用技术的效率对经济增长有正向的促进作用。并利用2004-2015年基础研究投入与经济增长相关面板数据进行了实证，实证结果支持了上述观点。
