本研究为投资决策的昼夜变化提出了一个新颖的理论框架。基于中国一家大型借贷型众筹平台的数据，本研究发现投资者在上午投资金额最多，在下午投资适中，在傍晚投资金额最少；他们在下午做出的投资决策最快，在上午投资适中，在傍晚投资最慢。此外，相较于电脑端，投资金额和速度的昼夜变化在手机端更为突出。本研究的结果为众筹文献做出了重要延伸，并为众筹平台的运营管理提供了管理启示。

This study proposes a novel theoretical framework for diurnal variations in investment decisions. We collect and analyze data from a large lending-based crowdfunding platform in China. We find robust evidence that investors invest most in the morning, moderately in the afternoon, and least in the evening; they invest fastest in the afternoon, moderately in the morning, and slowest in the evening. Furthermore, the diurnal variations in terms of investment amounts and speed become more prominent in mobile-based interactions than in desktop-based interactions. Our findings contribute to the crowdfunding literature and provide managerial implications for crowdfunding platforms.
