摘要: 数据资产作为数字经济时代企业的战略性资源,其信息披露引发了社会的广泛关注。然而,现有关于数据资产信息披露的实证研究还较少。以2007—2022年中国A股上市公司为样本,实证考察了数据资产信息披露对资本市场定价效率的影响。研究发现,数据资产信息披露能够降低公司的股价同步性。中间机制分析发现,数据资产信息披露可以降低公司内外部之间的信息不对称程度和提高投资者对公司的关注度,因而数据资产信息披露可以降低股价同步性。异质性检验发现,在机构投资者参与度高、分析师关注度高的公司中,数据资产信息披露对股价同步性的降低作用更明显。因此,为提高资本市场的定价效率,企业要积极推进数据资产的开发与运用;相关部门要加强对数据资产信息披露的监管。

Abstract: As a strategic resource for enterprises in the digital economy era, the disclosure of data assets has attracted widespread attention from society. However, there are still limited empirical researches on the disclosure of data asset information. Taking China’s A-share listed companies from 2007 to 2022 as samples, this study empirically examines the impact of data asset information disclosure on the pricing efficiency of the capital market. The findings show that disclosure of data asset information can reduce a company’s stock price synchronicity. The analysis of the intermediate mechanism reveals that the disclosure of data asset information can reduce the degree of asymmetry between internal and external information of a company and increase investors’ attention to the company, thus reducing the synchronicity of stock prices. The heterogeneity testing reveals that in companies with higher institutional investor participation and analyst attention, the effect of data asset information disclosure on reducing stock price synchronicity is more significant. Therefore, in order to improve the pricing efficiency of the capital market, enterprises should actively promote the development and utilization of data assets. The relevant departments should strengthen the supervision of data asset information disclosure.

Key words: data asset information disclosure, stock price synchronicity, capital market pricing efficiency, text analysis
