The invention provides a dynamic generating method of an application page supporting multiple terminal types. The method includes the steps of firstly, establishing a page instance with a layering relation for each supported terminal type on a server side, generating a control instance on the basis of the control property and service logic skip relation, assembling the control instance in the page instance, and storing control instance identification contained in page instance identification and the position of the control instance identification in the page instance in an ordered list; secondly, starting a terminal application, accessing the server side for control synchronizing, obtaining control properties and a control instance contained in the page instance, sending a page data obtaining request to the server side, recognizing the terminal type corresponding to the terminal application through the server side, assembling the completely-instantiated page data according to the page instance and returning the data, analyzing the page instance data through the terminal application, and executing a corresponding rendering code of the control in a rendering code base according to code identification of the control instance corresponding to the page instance in the ordered list and conducting rendering displaying.
