基于马克思生产函数的最优经济增长模型

摘要

The optimal economic growth and employment growth rate is closely related with the employment,the increase in the growth rate,the optimal growth rate will increase,but when it reaches a certain point,the im-proved employment growth rate will reduce the optimal economic growth rate.In the optimal economic growth la-bor intensity curve is a logical saturation curve,so at the left inflection point,employment growth rate and eco-nomic growth rate increase,and at the right end of the inflection point,the employment growth rate in contrast with the optimal economic growth rate changes direction.In addition,the relationship between the optimal eco-nomic growth rate and some parameters is close when long-term,optimal growth rate decreased gradually while the long-term optimal economic growth rate gradually increased.%文章根据马克思生产函数建立了马克思最优经济增长模型。模型显示，最优经济增长率与就业增长率密切相关，随着就业增长率的提高，最优经济增长率也会随之提高，但达到一定点后，再提高就业增长率就会降低最优经济增长率。在经济增长最优条件下劳动密集度曲线是一条逻辑斯特饱和曲线，因此在拐点的左端，就业增长率与经济增长率同步提高，在拐点的右端，就业增长率与最优经济增长率变化方向相反。此外最优经济增长率与分工参数关系密切，当产出就业弹性大于分工参数时，长期最优经济增长率逐渐下降；反之则逐渐上升。
