In the post-financial crisis Era, China's finance is facing the hitherto unknown pressure. In order to cope with the financial system problems that may arise, the financial regulation information has been put on the agenda. In 2012, the China's State Council issued the Twelve-Five-Year Plan of Chinese Government Information Construction. The financial regulation informatization projects are included in the national key construction projects. This paper aims to explore a software architecture that integrates financial regulatory system based on the Service Oriented Architecture and the ontology technology, so that it can integrate financial regulatory system of the People's Bank of China, the China Banking Regulatory Commission, the China Securities Regulatory Commission and the China Insurance Regulatory Commission, and give a technical proposal for the decision of the China's State Council. Our experiments show that the technology is feasible.
