In this model, we discuss the effect of tax policy on economic growth on the condition of market competitive equilibrium. Two chief conclusions are drawn: firstly, when the government has carried out steady tax policies, for consumers there exists unique optimal capital stock path along which economy can grow sostenuto and steadily; when the tax path given by the government converge to some constant tax rate, there still exists one capital stock path which can make the whole economy grow gradually and converge evenly to the optimal state.

在该模型中，我们讨论了在市场均衡条件下，税收政策对经济增长的影响，得到两个主要结论：一、当政府实行稳定的税收政策时，消费者存在着唯一的最优资本存量路径，沿着此路径经济能够持续平稳并且最优地增长；当政府给定的税收路径不稳定但能收敛到某个常值税收率时，此时也存在一条资本存量路径，它能使整个经济渐近平稳地增长，并且最终收敛到最优状态。
