And then the paper analyses the influence of the preference of share financing about the Chinese listed companies. The paper sets up the mode of the debt financing-internal cash flow sensitivity by analyzing Has financing constraints theories. And it selects the listed non-financial companies of Shanghai and Shenzhen stock markets to do the demonstration. Two conclusions can be reached from the empirical study:(1) There is a remarkable negative relativity existing between china's listed companies' debt financing and internal cash flow. As the increase of the internal cash flow, the company's debt will decrease. The sensitivity between the two inclines to strengthen with the lapse of time.

通过对融资约束的理论分析，本文建立了债务融资与内部现金流量敏感性分析模型，并以沪市和深市的非金融类上市公司作为样本进行线性回归分析，得出以下结论：(1)中国上市公司债务融资与内部现金流量之间存在着显著的负相关性，即随着内部现金流量的增加，企业的债务融资额将会减少，且随着时间的推移，二者的敏感性有增强的趋势。

This paper explores shareholder approach, material approach and investment approach to cash flow, and it is concluded as follows: Net present value calculated is equal for shareholder approach and material approach, but for fixed assets investment projects, shareholder approach is far more concise and workable than material approach and provides direct cash flow information with clear and useful economic significance. Investment approach analyzes forecast cash flow for investment projects from a different angle, not only offering additional managerial accounting information, but also testing the properness of and providing theoretical support for shareholder approach and material approach.

通过对股东现金流量法、实体现金流量法和全投资现金流量法模型的研讨，提出如下观点：股东现金流量法与实体现金流量法计算的净现值是相等的，但对寿命期有限的固定资产投资项目，股东现金流量法远比实体现金流量法简洁易懂，便于操作，其提供的现金流量信息直观，经济意义明晰，有用性强；全投资现金流量法从另一个角度进行投资项目的预期现金流量分析，不但能提供补充的管理用会计信息，而且能对股东现金流量法模型的正确性进行验证，互相提供理论上的支持。
