Nowadays, the credit industry of China's commercial banks is highly concentrated in industries such as manufacturing, wholesale and retail, which have high non-performing loan rates and low credit asset quality, leading to poor overall credit asset quality of commercial banks. Optimizing the industrial structure of commercial bank credit can effectively improve the quality of commercial bank assets. This paper evaluates the industrial structure of China's credit market from the perspective of industry, and proposes recommendations for the credit funds of different industries based on industry evaluation.
