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.

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。

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.

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

The decreasing conditions of an energy function are investigated by the use of convex function.

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

Results of analysis show that Generalized Paris Law can consider the complex crack propagation in the material of the pavement structure. The fatigue life of the pavement increases with increasing thickness of surface layer in a power function. Use of a thicker surface layer may extend the service life of the asphalt pavement. The fatigue life increases with decreasing modulus of surface layer in a power function with a negative exponent. However, since reduced modulus would scarify the structural strength and might cause rutting-related distress, caution should be taken when using low modulus materials for improving fatigue performance of asphalt pavements. The fatigue life increases with increasing modulus of base material in a power function. However, the fatigue life can not infinitely increases with increasing modulus of the base.

计算与分析表明:广义Paris公式可以考虑沥青路面结构内材料复杂的裂缝扩展:沥青面层的疲劳寿命随着面层厚度的增加以幂函数的形式增加,适当增加沥青面层厚度可以提高路面的使用寿命;沥青面层的疲劳寿命随着面层材料模量的降低以负指数的幂函数形式增加;由于材料模量的降低将牺牲路面的整体强度并可能引起路面车辙类损坏,以此提高疲劳寿命的方法应慎重对待;沥青面层的疲劳寿命随着基层材料模量的增加呈幂函数的形式增加,但由疲劳方程可以看出,寿命并不是随基层材料模量的增加而无限的增加,疲劳曲线在经过一个上升段后,逐渐趋于一个常数值,这说明,这时基层模量对寿命已不作关键性贡献;随着底基层厚度的增加,面层的疲劳寿命近似地呈线性函数增加,但效果并不很明显。
