The invention particularly relates to a government affair system integration method and device. The method is applied to a cloud end, the cloud stores a unified authentication center; the unified authentication center comprises at least one design mode module. The method comprises the following steps of: obtaining a sample; both the new government affair system and the old government affair system are migrated to the cloud; authority management logic in the old government affair system is removed; Each new government affair system and each old government affair system are split into a plurality of system modules according to different service scenarios, at least one design mode module is mounted according to the service process of each system module to obtain a target system module, and then the target system modules are integrated and published according to preset rules. Therefore, according to the scheme, the service flow function and the authority management function of the government affair system are separated, the authority management function is packaged through the design mode module, the service flow function and the authority management function are independently mounted in the system module, system coupling is reduced, and system integration and management are more convenient.
