毕业论文 （20_ _届） 钢铁行业上市公司股权特征与公司绩效研究 摘 要 2008年以来，以美国为中心的世界性金融危机横扫全球，各国股值全面大幅下跌，全球经济增长普遍放缓。本文在这样的背景下研究我国钢铁行业上市公司的股权结构对公司绩效的影响，希望对优化企业股权结构、提高企业公司绩效有所帮助。 本文在回顾国内外相关研究文献的基础上，分析了我国上市公司股权结构与公司绩效的现状，结合我国上市公司特有的股权结构特点，以在沪深两市上市的28家钢铁行业公司为研究样本，以股权结构为解释变量、以代表公司绩效的财务指标为被解释变量，应用SPSS统计软件对样本的股权结构与公司绩效之间的关系进行实证分析，初步证明钢铁行业上市公司股权集中度与公司绩效成正相关，股权制衡度与公司绩效无相关性。 关键词：Abstract Since 2008，the worldwide financial crisis has swept away the whole global which took the U.S. s the center.
