账面盈利与经营活动现金净流量的相关性研究——基于金属非金属行业上市公司的实证分析

Research on relationship between paper profit and operating cash flow——an empirical analysis based on listed companies in metal/nonmetal industries

对2004年中国证券市场上的129家金属和非金属行业上市公司的会计账面盈利与现金流量的相关性进行实证研究后,发现两者的相关程度很低,很大一部分上市公司的账面盈利没有形成相应的现金流入,导致两者之间产生“滞脱”的效应.因此,笔者认为在对企业的财务状况进行评价时,不能仅仅局限于使用一些反映企业账面盈利的指标,应该还需要考虑一些反映企业创造现金流量能力的指标.

After analyzing the correlation between the paper profit and cash flow in 129 listed companies in metal/nonmetal industries in stock market in 2004, it is found that there is low level correlation between paper profit and cash flow. The paper profit can not form into corresponding cash flow in many listed companies, which leads to an effect ＂lag effect＂. So this paper supposes that when the financial condition of a company is evaluated, it can not be only limited to these indexes which reflect the paper profits of a company. Some indexes reflecting the ability of creating cash flow in a company should be considered.
