摘要本文选用多元回归分析这一研究方法，对年沪深两市A股上市的化工企业的资料进行分析，完成股权集中度对公司绩效影响的实证研究。已有的关于股权集中度与公司绩效实证研究的结果呈现出很大的差异性，从而使实证研究失去了对企业的现实意义。实证研究应为企业或行业服务，所以，对一个行业的实证分析应成为实证研究的重点。
本文首先回顾了股权集中度的相关理念，其次对之前的研究进行了整理和分析，在前人分析的基础上，得到初步的假设，之后进行本文的实证部分。在实证部分中，本文选取了2008年之前沪深两市A股上市的化工行业上市公司，使用多元回归分析，以企业的绩效为被解释变量，以第一股东所持有的股权所占的比例，前十大股东所持有股权所占的比例，以及第一大股东和第二大股东持股比例之比为解释变量进行分析，实证结果表明：化工行业上市公司的绩效与第一大股东的持股比例成反比，与前十大股东的持股比例呈正比关系,与第一大股东和第二大股东持股比例之比成负相关关系。最后通过实证结果找出我过化工行业上市公司在股权集中度方面所存在的问题并提出相应的建议对策，对已上市的化工行业上市公司在股权集中度发面起到一定的现实意义。33010
