产业进入壁垒是现代产业组织理论和反托拉斯法研究中使用最广泛的概念之一,但现有产业进入壁垒的理论研究成果不能完美地解释产业内不同企业或企业类别之间盈利绩效差异的深层原因,因而有必要将现有的产业进入壁垒分析延伸到产业内部。本文的目的就是试图在析评现有产业进入壁垒定义及有关理论研究成果的基础上,构建一个分析导致同产业不同企业或企业类别盈利绩效差异的产业内壁垒概念。
Industrial barriers to entry is one of the most widely used concepts in modern industrial organization theory and antitrust law research. However, the theoretical research results of existing industrial barriers to entry can not perfectly explain the deep differences in earnings performance among different enterprises or types of enterprises Therefore, it is necessary to extend the existing industry barrier analysis into the industry. The purpose of this paper is to try to build a concept of industrial barriers that analyze the profitability of different enterprises or enterprises in the same industry based on the analysis of the definition of barriers to entry of existing industries and the related theoretical research results.
