会计信息质量与过度投资的关系研究

Research on the Relation between Accounting Information Quality and Over-investment

以我国2004-2006年制造业上市公司的数据为样本，对会计信息质量和企业过度投资的关系进行了实证研究。结果发现：会计信息质量与企业过度投资存在显著负相关，提高会计信息质量可以抑制企业的过度投资行为；在自由现金流量较多的上市公司中，会计信息质量与过度投资呈现出更强的负相关，提高会计信息质量能对该类企业的过度投资产生更大的治理效应。这为我国治理企业过度投资提供了新的路径。

Taken the data from listed companies of manufacturing industry in China during 2004 -2006 as a sample, the relation between accounting information quality and over-investment was studied empirically. It is found that accounting information quality is negatively corrected with firm over- investment and high quality accounting information can prevent over-investment. Further, accounting information quality is more closely associated with over-investment for firms with more free cash flow, which implicates that improving quality of accounting information could prevent over-investment of these firms.
