摘 要:本文通过描述统计和独立样本T检验的方法,对2001年-2010年中国上市公司的投资行为进行研究分析,阐述不同股权集中度和现金持有量与企业的投资行为的联系。得出:股权集中度与现金持有量都影响企业的投资行为。在股权高度分散与股权相对集中的情况下的企业投资行为无明显差异;股权高度分散和股权高度集中的情况下,除了存货投资无显著差异外,其他投资都表现为有显著差异;在股权相对集中与股权高度集中的情况下的所有的投资行为都表现为有显著差异。同时得出,在不同的现金持有量下,企业的投资行为都表现为有显著差异,而且随着现金持有量的增加,企业的投资行为增加,现金持有量与投资之间呈正比例变化。

研究思路与方法
本文主要分为以下几个部分:第一部分,绪论;第二部分,分析我国上市公司股改前后的股权集中度及现金持有量的特征;第三部分,不同股权集中度和现金持有量类型下企业投资行为差异;第四部分,企业投资行为的均值T检验;第五部分,结束语。
众所周知,按照不同的标准,可以将投资划分为不同的种类:按投资与企业生产经营的关系,可分为直接投资和间接投资;按投资回收时间的长短,可分为短期投资和长期投资;按投资的方向和范围,可分为对内投资和对外投资。本文将选取2001年以前上市的公司为样本,运用描述统计的方法,分析这些公司2001年-2010年期间的股权集中度与现金持有量对公司投资行为的影响,得出相应的结论。
