银行业竞争与企业规模分布——基于工业企业数据的实证分析

Banking Competition and the Firm Size Distribution-Empirical Analysis on Industrial Enterprise Data

结合中国工业企业数据库与银行业竞争数据,实证检验银行业竞争对企业规模分布状态的影响。研究发现:样本期间内我国企业规模分布Pareto指数呈现逐年上升的趋势,表明企业规模分布越来越均匀;银行业竞争对不同规模等级企业的成长具有非均衡性影响,更加有利于中小企业成长,进而促使企业规模分布更加均匀。一系列检验均表明上述结论非常稳健,可优化我国企业规模分布和促进产业结构转型提供新的思路。

The distribution of firm size is an important research issue in the fields of firm entry,exit and industrial structure adjustment.However,few scholars have studied the issue from the perspective of banking competition.We combine Annual Survey of Industrial Firms of China from 1999 to 2007 and the data of banking competition to empirically test the influence of banking competition on the state of firm size distribution.The results are as follows.First,the Pareto index of the firm size distribution increases year by year,which indicates the overall firm size becomes more and more uniform.Second,the banking competition has unbalanced effect on the growth of firms in different scales and is more favorable to the growth of small and medium-sized enterprises,thus making the distribution more uniform.A series of tests show that the above conclusion are very robust.The research provides a new idea to optimize the firm size distribution and promote the transformation of industrial structure.
