The sze distribution of firms in any industry is usually highly skew, and empirical evidence shows that it is approximated closely by by the Pareto distribution. There are many attempts to explain the mechanisms that generate the Pareto distribution by constructing models with stochastic processes. The most ingenious model among them is the one developed by Simon (1955), which is based on the law of proportionate effects and the constant new entry of firms. However, his model dose not make it clear how those assumptions are related to the behavior of firms. In this paper we make an attempts to relate those assumptions to the innovation and investment behavior of firms. We will explain the generation of the Pareto distibution of firms by assuming that firms, which make new entries from the minimum sise, acquire technologies of operating more efficiently on a larger scale through learning by doing, and expand their scale of operation through accumulation of capital induced by profitability.
