【摘要】 运用最近兴起的随机前沿技术,研究了产品市场竞争对公司效率的作用。不同的竞争激烈程度上,产品市场竞争与公司效率之间作用是不同的。在竞争激烈程度中等的行业,产品市场竞争与公司效率之间是"倒U型"的曲线关系。在竞争激烈和竞争不激烈的行业中,产品市场竞争与公司效率之间是一次正的线性关系。同时,大公司的存在能够促进公司效率的提高。另外,中国上市公司效率与行业竞争强度之间并没有表现出相互影响的关系,"效率结构假说"不成立。更多还原

【Abstract】 This paper analyzed the relationship between product market competition and corporate efficiency using the stochastic frontier technology.The effect of competition is different with competition extent.In highly competing industries,competition is positive to efficiency.This correlation also exists in lowly competing industries.In middle competing industries,the relationship is the "inverted U-type" curve.Meanwhile,we find the existence of large company can improve the efficiency for companies.By the way,we find that efficiency-structure hypothesis is not reasonable for China listed companies.更多还原
