Can upgrading information infrastructure improve the innovation ability of companies? Empirical evidence from China

The development of information technology has become a new driving force for companies' innovation. Upgrading the information infrastructure lays a foundation for companies to use information technology to innovate; therefore, this study examines the impact of information infrastructure upgrading on companies' innovation ability and the intermediate mechanism. Using a sample of China's listed companies of A-share from 2011 to 2018, this study used the staggered difference-in-difference method to investigate the impact of information infrastructure upgrading on innovation input, innovation output and quality. The results show that upgrading information infrastructure has a 'double-edged sword' effect on the innovation ability of companies. Companies' innovation input and output significantly increase, but innovation quality decreases. Additionally, further analysis indicates that financial constraints and managerial myopia are intermediary mechanisms for this effect. Our research results provide theoretical and empirical evidence for companies to enhance their innovation ability.
