本文利用中国家庭金融调查的数据,研究了信息多样性在家庭投资组合多元化中的作用。我们首先提出了一种包含信息渠道和信息领域(即人们关注的信息话题)的信息多样性指数。随后,实证检验表明,信息多样性显著影响家庭对股票、基金和保险市场的参与。我们进一步构建了家庭投资组合多元化指数,发现信息多样性对投资组合多元化也有显著的正向影响。此外,信息多样性与投资组合收益之间存在正相关关系。最后,本研究确定了经济和金融信息的关键作用;如果缺乏这些信息,信息多样性在某些情况下不会产生同样的积极影响。
This study focuses on the role of information diversity in household portfolio diversification, using data from the China Household Financial Survey. We first propose a novel information diversity index which incorporates both information channels and information fields (i.e., information topics people pay attention to). Subsequently, empirical tests demonstrate that information diversity significantly affects households' participation in stock, fund and insurance markets. We further construct a household portfolio diversification index and find that information diversity also has a significant positive effect on portfolio diversification. Furthermore, a positive relationship between information diversity and portfolio returns is confirmed. Finally, this study identifies the crucial role of economic and financial information; if this information is lacking, information diversity does not have the same positive impact in some cases.
