摘 要: 在生产函数为一般形式时,利用控制论及定性理论的基本方法,讨论政府支出的生产效应和此时的财政政策。得出了当生产函数为规模收益不变、递增和递减时,经济增长率的大小及此时相关经济变量的定性结构,并指出了各种情况下相关参数如何对经济增长率产生影响。结果发现:生产函数为规模收益不变时,模型简化为A-K模型;生产函数为规模收益递增时,均衡点为不稳定结点;生产函数为规模收益递减时,均衡点为鞍点稳定。
关 键 词: 数理经济学;经济增长;政府支出;生产效应

Abstract: When the production function was general, using theory of control and theory of stability, this paper discussed the production effect of government expenditure and fiscal policy, and got the expression of economic growth rate and structure stability of the economic variables when the production function was constant return to scale or increasing return to scale or decreasing return to scale, and pointed out how the interrelated parameters affected economic growth rate. It was shown that when the production function was constant return to scale, the model became a A-K model; when the production function was increasing return to scale, the equilibrium point was unstable; when the production function was decreasing return to scale, the equilibrium point was a saddle.
Key words: mathematical economics; economic growth; government expenditure; production effect
