Abstract: In order to explore the impact of institutional pressure on corporate social responsibility information disclosure, from the perspective of legitimacy, this paper incorporates the time dimension and constructs a system dynamics model of institutional pressure, strategic response and corporate social responsibility information disclosure by categorizing institutional pressure into coercive pressure, normative pressure and mimetic pressure, and uses Vensim PLE software to conduct model test, simulation and sensitivity analysis. It is found that institutional pressure can affect corporate social responsibility information disclosure through three strategic responses, namely conformity type, selection type and manipulation type; with the respective value increase of coercive pressure, normative pressure and mimetic pressure, the amount of corporate social responsibility information disclosure under different strategic responses increases. The impact of coercive pressure, normative pressure and mimetic pressure on corporate social responsibility information disclosure is gradually enhanced. The research results can provide suggestions for enterprises to choose reasonable strategic responses under institutional pressure and disclose social responsibility information properly.

Key words: institutional pressure, strategic response, corporate social responsibility information disclosure, system dynamics
