Due to the fact that some companies are overly pursuing profit maximization and thus neglecting the issue of undertaking and fulfilling Corporate Social Responsibility (CSR), the situation of investment risks due to information asymmetry has arisen. Whether corporate social responsibility information disclosure can solve the information asymmetry in the market economy, help enterprises to reduce the cost of external capital, and improve the efficiency of corporate investment is now the hot topic of concern for many economists. Regardless of the type of enterprise, the choice of investment projects depends on the investment opportunities faced. However, there will be financial market friction resulting in the actual investment volume of the enterprise deviates from the optimal investment scale, which will have a certain impact on the company's social image. Therefore, this article analyzes the impact of corporate social responsibility information disclosure on corporate investment, hoping to enrich the existing research results on corporate investment efficiency in the field of corporate social responsibility, standardize corporate responsibility information disclosure systems, and improve investment efficiency.
