摘要
尽管基础研究经费在不断增加,但在过去的20年间我国基础研究强度始终维持在一个低水平均衡状态。本文在借鉴内生增长理论A H模型基本结论的基础上,从知识积累的角度尝试对这一问题进行解释。研究表明基础研究强度与基础研究生产知识的弹性系数正相关,而与应用研究投入(尤其是导向型科学研究)对基础科学新知识的弹性、"干中学"学习效率负相关。并据此结论对我国基础研究强度长期维持低水平均衡状态原因做出尝试性解释。
From 1987 to 2006, the basic research investment has increased by 12 times in China. It seems that Chinese basic research intensity falls into ＂the trap of low level equilibration＂. Based on the conclusion of Aghion ＆ Howitt model （1992） in neo - Schumpeterian endogenous growth theory, from the angle of knowledge accumulation, the problem involving Chinese basic research is made an attempt to explain. In the state of equilibration, a nation＇ s basic research intensity is decided by the contribution of various types of knowledge to the whole knowledge accumulation, such as, production elasticity of basic research, the elasticity of applied research investment to new knowledge of basic science, learning efficiency of ＂learning by doing＂, etc. These contribution parameters determine Chinese basic research intensity.
