Employing Structural Equation Modelling to evaluate the hypotheses, the research obtains that: (1) financial innovation (FI) is negatively associated with investment decisions (ID), and positively related to employee satisfaction (ES), customer satisfaction (CS), and bank performance (BP). (2) BP, CS, ES, and IS are related significantly and positively to ID. (3) BP, CS, and employee satisfaction do mediate the relationship between FI and ID. (4) Internet security does not moderate the effect of FI on ID. The investigation emphasizes the role of financial innovation and Internet security in investment decision-making for the providers of financial innovation services. Certainly, it recommends that financial institutions should consider this as well as internet security in their investment decisions.
