Enhancing investment efficiency through improved information disclosure

This study investigates the effect of information disclosure on the investment efficiency of China's A-share listed companies over the period 2018-2022. Our results demonstrate that enhancing the quality of information disclosure leads to a substantial improvement in investment efficiency. By reducing information asymmetry and acting as a signaling mechanism, adequate information disclosure encourages greater investor propensity and investment scale, ultimately promoting investment efficiency. Additionally, we find that improving information disclosure quality mitigates the cost of financing constraints, thereby alleviating financial pressures associated with underinvestment.
