经营、投资和筹资现金流动态交互影响分析

本文提出系统现金流的面板向量自回归模型(Panel Vector Autoregression,PVAR)考察经营、投资和筹资现金流三者间的动态交互影响效应。该模型不但解决了变量内生性问题,并且有效刻画了系统变量间的冲击反应。敏感度分析与方差分解的结果表明:中国制造业上市公司投资现金流对经营现金流具有突出的敏感性,而投资现金流的波动则更多地受到筹资现金流的波动影响。正交冲击反应分析则进一步表明:经营现金流对投资、筹资现金流冲击的反应不显著,而投资现金流对经营、筹资现金流冲击的反应要持续较长时间,并且筹资现金流与经营现金流具有一定程度上的短期替代作用。以上研究结果分别从现金流敏感度和现金流波动性两个角度说明中国制造业上市公司存在外部融资约束问题。

The Dynamic Interacting Relationships Among the Operating,Investing and Financing Cash Flows

This paper investigates the dynamic interacting relationships between the operating,investing and financing cash flows with a Panel Vector Autoregression(PVAR) model,which treats the above three variables as a system,mitigates the problem of endogeneity in the estimation,and displays the responses of one variable to the shocks from the others in the cash flow system.With the sample of the listed firms of China's manufacturing industry,the results of the sensitivity analysis of the coefficients and variance ...
