企业在不确定环境下的投资决策一直是经济学和金融学关注的焦点问题。本文从国内外研究现状着手,对不确定性与企业投资效率关系的文献进行了归纳分析,发现主流研究普遍认为不确定性对企业投资具有抑制作用。即不确定性越大,企业投资效率越低,具体表现为由不确定性引起的投资不足程度更高。通过对不确定性影响投资效率的相关文献进行系统梳理,为以后相关研究奠定了理论基础。
The investment decision of enterprises in uncertain environment has always been the focus of attention in economics and finance. This paper starts with the research status at home and abroad, and summarizes the literature about the relationship between the uncertainty and the investment efficiency of enterprises. It is found that the mainstream research generally holds that the uncertainty has an inhibitory effect on the corporate investment. That is, the greater uncertainty, the lower the efficiency of business investment, the specific performance of the investment caused by the uncertainty of the higher degree. By systematically combing the literature on the impact of investment uncertainty on uncertainty, it laid the theoretical foundation for future research.
