一个多资本的Learning-by-doing模型

考虑一个多资本投入的一般Learning-by-doing模型。该模型技术进步的增长率由经济发展过程内生地决定。当技术对资本为递减规模回报时，该经济仅有唯一正的均衡点。运用单调动力系统理论论证了此模型的稳定性问题，求出了这种经济的收敛速度。

A Learning-by-doing Model with Multiple Capitals

Based on the traditional learning-by-doing model, a general economic growth model about Multiple Capital is presented. The growth rate of technological progress is endogenously decided by the process of economic development, as A(*) exhibits decreasing returns to scale, there is only one positive balanced point in steady state no matter whether the elasticity of output with respect to capital and effective labour are constant and there is the same growth rate between each capital and output. The model′s economic convergence speed is derived by using the theory of monotone dynamic systems which proves that the economy model will be asymptotically stable after a long time in a certain condition no matter where the economic starting point is.
