摘　　要：构建了一个两期经济模型,理论上研究了异质信念如何通过增长机会影响企业估值,并以2007~2020年沪深两市2 973家A股上市公司为研究样本,进行实证检验。研究结果表明:异质信念对企业估值具有正向影响;在研发强度高、专利授权多以及高科技行业,由于企业拥有较多的增长机会,异质信念对企业估值的正向影响更强;增长机会被执行之后,异质信念对企业估值的正向影响消失。即便考虑内生性问题以及更换关键变量的测度指标,实证结果依然稳健。By building a two-period economic model, this paper theoretically studies the effect of heterogeneous beliefs on firm valuation through growth opportunity, and then conducts empirical tests based on a sample of 2 973 A-share listed companies in Shanghai and Shenzhen Stock Exchanges from 2007 to 2020. The results show that heterogeneous beliefs have positive effect on firm valuation. The positive effect is more pronounced for firms with a higher research and development intensity, more patents granted, or firms in high-tech industries because these firms are endowed with more growth opportunities. Moreover, the positive effect would disappear once their growth opportunities are exercised. The Empirical results are robust even considering endogenous problems and changing measures of the key variables.
