市场集中度与大企业竞争力实证分析——基于中国装备制造业的经验证据

A Positive Analysis of the Market Concentration and the Competitiveness of Large Enterprises:Based on the Empirical Evidence of China's Equipment Manufacturing Industries

作为衡量市场结构的重要变量,市场集中度会通过影响市场环境而影响大企业竞争力的形成和维持。基于中国装备制造业226家大企业及其所在的80个4位数产业部门的面板数据,对市场集中度与大企业竞争力的关系进行了实证检验。研究发现,市场集中度变量对大企业竞争力表现出了显著的正向效应,说明我国装备制造业的市场寡占程度越高,市场中大企业的竞争力就越强;而市场壁垒变量并没有表现出显著的正效应,产业增长指标对大企业竞争力表现出了显著的正向影响。
