总供给曲线的推导是宏观经济学中的最重要内容之一。在大多数宏观经济模型中 ,在推导总供给曲线时 ,加总问题 (aggregationproblem)往往被忽略。一般认为 ,总供给曲线是各企业供给曲线的简单算术和或是一个代表性企业供给曲线的简单放大。但是 ,在现实中 ,各个企业是不同的。只有在非常严格的条件下 ,总供给曲线与企业供给曲线在性质上才是等价的。考虑到中国经济的制度性特点并在解决加总的一系列技术问题的基础上 ,本文推导出了在企业劳动生产率服从均匀分布情况下的总供给曲线。通过这种方法推出的总供给曲线具有许多传统总供给曲线所不具有的新性质。笔者希望本文能为进一步研究处于微观经济和宏观经济之间的往往被忽视的一块重要领域 (“中观经济领域”)做出贡献。
The derivation of the aggregate supply curve is one of the most important elements in macroeconomics. In most macroeconomic models, aggregate problems are often overlooked in deriving the aggregate supply curve. It is generally accepted that the aggregate supply curve is a simple exponential of the supply curve of each firm and a simple magnification of the supply curve of a representative firm. However, in reality, all enterprises are different. Only under very strict conditions, the aggregate supply curve and the firm supply curve are qualitatively equivalent. Considering the institutional characteristics of China’s economy and solving a series of technical problems that are summed up, this paper deduces the total supply curve under the uniform distribution of labor productivity of enterprises. The total supply curve introduced by this method has many new properties that traditional total supply curves do not have. The author hopes that this article can contribute to the further study of an important area that is often overlooked between the micro-economy and the macro-economy (“the mid-range economy”).
