(一)柯伯—道格拉斯(Cobb—Doglas)生产函数技术进步度量数学模式生产函数是社会生产的一种技术关系。它是对生产活动中投入与产出之间的技术关系的一种概括。生产函数可以有不同的形式,如表格、曲线图或数学公式。在西方经济理论中,最简单的生产函数数学公式是柯伯—道格拉斯函数。即 Q=AKαLβ………(1) 式中Q是产出,K是资本存量(固定资产总值),L是劳动数量,A是一个常数。
A. Cobb-Doglas Production Functions Technical Progress Measures Mathematical Models Production functions are a technological relationship of social production. It is a generalization of the technical relationship between inputs and outputs in productive activities. Production functions can take different forms, such as tables, graphs or mathematical formulas. In Western economic theory, the simplest mathematical formula for the production function is the Cobb-Douglas function. Q = AKαLβ (1) where Q is the output, K is the capital stock (the total value of fixed assets), L is the labor quantity, and A is a constant.
