The invention relates to a dynamic component loading method and system based on a plug-in mechanism. The method comprises the following steps that after an application program or component receives instructions requiring the calling of corresponding functions in other components, the other components are found, the other components provide a standard plug-in interface, and the unique MIME type for identifying the identity is realized; after the components are found, the components are loaded into a memory, an interface for creating the component instance is obtained, and the corresponding function interface of the components is called; when the corresponding functions are not needed, a component unloading interface is called, and the other components are unloaded. The interface adopted in the embodiment of the invention is a standard plug-in interface, the assembly is not linked during the compiling, unnecessary components are not loaded during the application program starting, the memory is saved, and the generation of application programs in different versions by aiming at embedded systems in different service forms is avoided.
