经济增长理论的一种表述

经济增长理论都是围绕生产函数来构造模型,但过去的理论都试图用生产要素直接构造生产函数,模型中必须引入严格的假设条件,从而使得模型对现实经济现象的解释力受到影响。如果借助数学中“隐函数”的思想,将生产函数分为不同的层次,每个层次的生产函数都尽可能地少用假设条件。尤其是第一层次的生产函数,直接用总消费,总投资等经济总量作为自变量,推导出自动满足一阶齐次等条件的生产函数,代替难以计量的生产要素构造的生产函数,就使得函数的适用性更广,解释力更强。

ONE EXPRESSION OF ECONOMIC GROWTH THEORY

Economic growth models were generally constituted by production functions, and we traditionally tried to organize production functions by production elements directly, that means ideal models count on strict hypotheses, thus comes the restrictions on their applicability in the realistic economic phenomena. This thesis divides production functions into different layers with the help of a mathematic idea of incognito functions, and tries to reduce the using of hypothesis conditions in each layer of production functions, especially in the first layer of production functions. When total economic values like total expenditure and total investments are set as independent variables, instead of those uncalculated production elements, the production function will be more suitable and more applicable for the explanation of our economic world.
