After the reform of interest rate marketization, in order to study the impact of loan interest rate marketization on the investment decision-making of listed enterprises and give the decisive role of the market in the allocation of resources, China needed to pay attention to the mechanism of loan interest rate marketization on the investment efficiency of listed enterprises.

The results showed that the marketization of loan interest rates improved investment efficiency by inhibiting inefficient investment. The intermediary effect showed that the marketization of loan interest rates improved investment efficiency by alleviating financing constraints. The conclusions of this study were of great significance for improving the reform of China’s market economy system and promoting the high-quality development of China’s economy.
