| 摘 要： 现金持有量和盈利能力是公司管理的两个重要方面。现金作为一项资产，其持有量的多少会影响企业的经营状况和盈利能力。研究现金持有量与盈利能力关系不仅充实了现金持有量理论和公司治理理论，还有利于公司对现金进行有效管理，帮助投资者做出最佳的投资决策。以2005-2010年间1155家A股上市公司为样本，以现金资产占比与货币资金为被解释变量，以总资产报酬率、净资产报酬率、主营业务净利率和净利润为解释变量，建立线性回归模型，对现金持有量与盈利能力的关系进行了实证检验。结果表明，现金持有量与盈利能力呈正相关关系。其中，现金持有量与净利润呈显著的正相关关系；现金资产占比与净资产报酬率呈显著的正相关关系，与总资产报酬率、主营业务净利率也呈正相关关系，但线性关系不显著。 |
