Using China's A-share listed companies as a sample, this paper provides empirical evidence that with the deepening of financialisation in non-financial corporate sector, the level of corporate risk-taking is significantly reduced, and the complete mediating effect is R&D innovation. The results are still robust when we use instrumental variable method, and the negative impact of financialisation on corporate risk taking is significantly reduced under the constraints of a good governance mechanism. It is further found that as the degree of financialization in non-financial corporate sector deepens, even if enterprises have the ability to take risks, they have no willingness to take risks. This paper theoretically demonstrates the micro-inducement of the insufficient motivation for enterprise development, under the “siphon effect” of financialization. | Financialization and risk taking of non-financial corporations empirical evidence from Chinese listed companies
