In recent years，with the rise of financial integrated operation，China’s large financial institutions have made gradual attempts on integrated operation，while non-financial institutions have also involved themselves in financial business for their own interests，which leads to a large number of financial holding companies or financial groups with different structures and varying degrees of synergy. However，in the absence of effective regulation，financial chaos caused by various financial groups continues and financial risks have become increasingly noticeable，threatening the stability of China’s financial market. It is suggested in this paper that laws and rules should be made to regulate financial holding companies，focusing on the regulation of non-financial institutions involved in financial businesses and regulating different institutions with disparate methods，so as to figure out the relationship between the financial sector and the real economy and to effectively prevent the systematic financial risks.
