Abstract:  To promote the deep integration and coordinated development of China′s finance and technology, the characteristics and connotation of ′Finance-Technology′ coupling vulnerability based on the vulnerability theory are analyzed According to the internal structure of the coupling system, an evaluation index system is constructed to evaluate the vulnerability of the coupling system by using the clustering analysis method, and a comprehensive evaluation model is also established to calculate the vulnerability of China′s ′Finance-Technology′ coupling system from 2007 to 2016 with correlation data The study shows that China′s ′Finance-Technology′ coupling vulnerability index has evolved from heavier vulnerability to mild vulnerability, but it has been slowly rising in recent years The explanation for this is that during the financial crisis, the vulnerability index was relatively high, and a series of policies introduced after the crisis effectively reduced the vulnerability index Then, due to the volatility of the financial market, the unbalanced development of the science and technology system structure, the low-level maturity of technology and the lagging development of regulatory technology, the ′Finance-Technology′ coupling vulnerability index has an upward trend

Key words:  Finance-Technology, coupling, vulnerability
