Based on the Moran Index (MI), which reflects the relationship between pollution status and the geographic and spatial characteristics of pollution. This study further discussed the impact of changes in financial and economic structure, pollution and spatial characteristics on urban sewage discharge. The results showed that when the pollution is highly correlated with spatial characteristics, the scale of urban sewage discharge would be larger, and the overall environmental regulatory status of the city would be worse. In terms of regional differences, the distance between cities in the central region and provincial capitals had a negative impact on the efficiency of sewage discharge. Finally, quantile regression found that when the efficiency of urban sewage discharge was in the higher quantile, the growth of labor disposable income and GDP would further enhance the discharge efficiency.
