本文讨论了生产力分散的典型事实、理论和遗留问题，这些问题本质上与新古典理论中的均衡概念有关。对日本企业相关数据的实证研究表明，它们都服从帕累托定律，而且帕累托指数随着集聚程度的提高而降低。为了解释这两个程式化的事实，我们提出了一个理论框架，该框架建立在统计物理学的基本原理和超级统计的概念之上，超级统计是一种适应总需求波动的方法。我们发现，生产要素的配置主要取决于总需求水平，总需求水平越高，经济越接近生产可能性集的前沿。
This paper discusses the stylized facts, the theory, and the remaining problems of productivity dispersion, which is essentially related to the concept of equilibrium in the neoclassical theory. Empirical study of data relating to Japanese firms shows that they all obey the Pareto law, and also that the Pareto index decreases with the level of aggregation. In order to explain these two stylized facts we propose a theoretical framework built on the basic principle of statistical physics and on the concept of superstatistics, an approach that accommodates fluctuations of aggregate demand. We show that the allocation of production factors depends crucially on the level of aggregate demand, and that the higher the level of aggregate demand, the closer the economy is to the frontier of the production possibility set.
