Huzhou urban medical alliance was a new urban and rural of medical alliance mode based on level 4 vertical integration, which played an important role in the whole evolution process of the medical alliance. This medical alliance had not only broken through the " integration of counties" but also explored the " integration of cities" . It was a bridge connecting counties and cities, which was of great significance in narrowing the gap between urban and rural medical health services. The construction of urban medical alliance took digital transformation and systematic integration as two breakthroughs to comprehensively promote the upgrade of energy efficiency and benefit stacking of health governance. In 2021, the grass-roots medical utilization rate and county-level medical utilization rate were 72.7% and 90.6%. In 2020, the average hospitalization cost(8 726.7 yuan)and the average outpatient and emergency expenses(239.6 yuan)of public hospitals were 25.0% and 8.6% lower than the average level of Zhejiang Province, respectively.
