The quality of the innovative development of the urban commercial banks is related to the high-quality development of the local economy and society. It is generally believed that, compared with the large national banks, urban commercial banks have insufficient own capital and limited operation areas, resulting in limited profitability. Exploring the innovation of credit asset securitization can improve their own profitability. In this paper, the panel data of the top 10 urban commercial banks in the issuance scale of credit asset securitization are selected for empirical research. The empirical results show that the credit asset securitization business has not significantly improved the profitability of asset assets of urban commercial banks, which is inconsistent with the general view. The reason is that through the analysis of credit asset securitization cases of urban commercial banks, it is found that the biggest motivation of urban commercial banks to promote credit asset securitization business is not to increase profits, but based on the consideration of sustainable operation and maintaining brand reputation.
