技术进步的边际产出测定法

A Method for Determining the Rate of Tech Change by Marginal Output Analysis

以投入产出的观点来分析,经济的增长基本上由三部分组成:第一部分是投入劳动力的增加;第二部分是投入资金的增加,包括厂房、设备、投资等;第三部分是技术进步,包括科学技术成果的采用,科学管理水平的提高和职工文化技术水平的提高等。正确估算技术进步在经济增长中的作用。

The marginal output method for determining the rate of tech change is a method derived from COBB-DOUGLAS function. It has the same differential form of output growth rate as Solow formula. However, it is sophisticate for Solow formula to find the values of the output elasticity of capital labor by statistical regression. While the method derived in this paper is more easy to determine directly these values by a practical computing formula.
