市场竞争与公司产出——我国市场竞争状况与公司产出之间关系讨论沈远鹏中文摘要始于上世纪 70 年代末的市场经济改革使得中国各个行业的市场竞争状况都发生了巨大变化，这场变化令无数曾己辉煌的公司从人们的视野中消逝，也令无数默默无闻的公司成就为市场大鳄。市场竞争状况对公司经营业绩的影响究竟如何，中外经济学界有着不同看法。本文以国外权威杂志所发表的一篇关于市场竞争状况与公司经营业绩之间关系的统计检验文章为契机，在该文提出的检验模型根底上结合中国现阶段实际情况提出了一简化的非时间序列模型，选取中国局部上市公司为样本进行统计检验，以考查中国市场竞争状况对中国上市公司经营业绩的影响。关键词：市场竞争、经营业绩、统计检验AbstractThe market competition environment in China has so much changed since the Reform at 1970’s.
