摘要
规模报酬不变还是规模报酬递增,往往是许多理论模型的研究假设前提。在一般的经济增长理论与模型基础上对规模报酬问题进行了分析,并对中国1978~2004年的规模报酬进行了检验,并采用PanelData模型检验了五个OECD国家的规模报酬问题。研究表明,规模报酬不变的假设前提将导致要素实际贡献额估计有偏。规模报酬不变的假设不适合分析现代经济发展,这也正是许多理论模型解释现实遇到困难的原因之一。
The constant or increase returns to scale is the assumption of many economic theoretical models. This paper analyzes the issue of returns to scale under the normal economic growth theory. Returns to scale is also studied on economy of China from the year of 1978 to 2004. Panel Data model is taken to study on it of five OECD countries. The result indicates that the assumption of constant returns is not suitable for the modern economy. This is one of the reasons that many theoretical models are encountered difficulties.
