内容提要：干 —— 扩大投资，增加资本要素的投入数量，能否产生技术创新，创造出知识 —— 即学？随着“干”所产生的“学”的数量和知识的积累，对经济增长带来哪三种不同的影响？我国改革开放30年所走过的历程是干中学（learning by doing）吗？这是本文要讨论的问题。
本文分三个部分，一、“干中学”模型在经济增长理论中的地位。二、通过一个“干中学”模型，分析依赖于资本的知识积累、技术创新可能导致经济增长的三种路径 —— 稳定性均衡、非稳定性均衡和介于两者之间的半稳定性均衡。三、根据“干中学”模型的结论，判断我国改革开放30年来的经济增长属于哪种路径，对于如何进一步在“干”中“学”到，提高我国经济增长率，提出具体政策建议。

’s economic growth path through
learning by doing model
【Abstract】Could doing, which means expanding investments and increasing the amount of capital inputs, enhance technology innovation and generate knowledge, namely, learning? Along with the accumulation of knowledge and quantity of learning resulted from doing, how many sorts of impacts on economic growth does it exist? Is

This paper is divided into three parts: First, illustrate the status of learning by doing model in the field of economic growth theory and the actuality of related studies in
China
. Second, through a learning by doing model, analyze three possible economic growth paths depended on the accumulation of knowledge and technology innovation—stable equilibrium, non-stable equilibrium and semi-stable equilibrium. Third, according to the conclusions of learning by doing model, judge the type of
China
’s economic growth path and give some specific suggestions on learning by doing and increasing the rate of economic growth.
