Private Enterprises'Self-Investment Inflation and Restraint Solutions

西方经济学从收益和成本角度对企业规模理论进行了大量研究,指出企业在一定的内部资源和社会条件下存在一个最佳边界,超出此边界则产生无效率投资。随着经济的发展,企业发展的“外部性成本”更加突出,企业的边界不仅要受到内部成本和收益的制约,还要受到维护公共利益的外部“权力”的制约。以现代企业理论为基础,以“铁本”事件为背景,阐述经济体制改革过程中民营经济忽略企业的“外部性成本”而导致的投资膨胀问题,并指出相关对策。

From the angle of returns and costs, the western economics do much research in the enterprise scale theory, it is pointed out that there is a best boundary in enterprises under certain interior sources and social conditions ,once overpassing the boundary, it will lead to ineffective investment. With the development of economy, the “exterior cost” plays a more and more outstanding role in the development of enterprises. The boundary is not only restricted by interior costs and returns, but also “exterior authority” which defends public interest. Based on the modern enterprise theory and backgrounded on the “Tieben event” ,the problem of investment inflation caused by ignoring the “exterior cost” in privately operated economy is elaborated and some relative solutions and suggestions are pointed out.
