The invention discloses an edge service supply optimization method based on dynamic resource allocation. The edge service supply optimization method comprises the following steps: S1, quantifying andmodeling the service use experience of a mobile user; and S2, carrying out a user experience quality optimization method based on service resource dynamic adjustment. According to the method, a quantization strategy of user experience quality is put forward for service supply optimization in an edge computing framework for the first time, a dynamic resource allocation strategy scheme is put forward, and a new feasible and reliable method is provided for providing an optimization scheme for edge computing services utilizing service distributed characteristics. On the basis of considering the interaction information between the user and the edge server, the resource-performance relation between the edge server resource and the service processing capability and the time sequence relationshipof the service request are comprehensively considered; and the information are utilized to provide assistance for the dynamic adjustment strategy of the edge server during operation, resources of theedge computing component can be better utilized, and high-quality user experience is provided for a service user.
