信息技术(系统)既可以减少企业内部的协调成本和生产成本,又可以减少企业与市场之间的协调成本,因此信息技术(系统)对企业规模的影响存在两种效果。通过收集沪深76家上市公司大约400个样本观察值组成的非平衡面板数据,本文在我国背景下实证检验了信息系统与企业规模(以员工总数和资产总值来衡量)的关系,实证研究发现,使用信息系统后,上市公司的规模在统计上显著减小了。本文还对ERP与企业规模的关系进行了实证检验,研究发现使用ERP后,上市公司的规模在统计上显著减小了。
Information technology (system) can reduce the coordination cost and production cost within the enterprise and reduce the coordination cost between the enterprise and the market. Therefore, the influence of information technology (system) on the enterprise scale has two effects. By collecting non-equilibrium panel data of about 400 sample observations of 76 listed companies in Shanghai and Shenzhen, this paper empirically tests the relationship between information system and firm size (measured by the total number of employees and the total assets) in our country. The empirical study Found that the use of information systems, the size of the listed companies statistically significantly reduced. This paper also empirically tests the relationship between ERP and firm size, and finds that after using ERP, the size of listed companies decreases statistically.
