The development of information technology continues to improve the density of enterprise information, which has an important impact on the creation of enterprise value. Based on the data of Shanghai and Shenzhen listed companies from 2008 to 2020, this paper conducts an empirical test. The results show that the density of informatization has a significant positive impact on the creation of enterprise, among which social trust plays a positive moderating role. Under the moderating effect of social trust, the information density will promote the increase of enterprise investment return,the reduction of captial cost and the increase of sustainable growth rate,and ultimately increase the level of enterprise value creation. The influence of informationdensityhas a Matthew effect, indicating that regional development is not sufficient and unbalanced in China. Further research shows that the positive effect of information density on enterprise value creation is more significant in capital-intensive and technology-intensive industries. The conclusion above has important enlightenment significance for relying on the new generation of information technology to strengthen the construction of information infrastructure and enhance the level of enterprisevalue creation.
