**Abstract:** Social responsibility performance and innovation investment are two important aspects of corporate strategy, and there is no consensus as to whether they are competing or complementary goals in an enterprise. Using propensity score-matching, ordinary least squares, and quantile regression, the study shows that the voluntary disclosure of social responsibility by enterprises will increase innovation investment. In other words, corporate social responsibility has a significant positive impact on innovation and investment; however, with the increase in enterprise innovation investment, this impact gradually weakens.
