在科技自立自强的背景下，企业实施负责任创新对自身乃至整个社会的可持续发展都起着至关重要的作用。尽管负责任创新的重要性已被广泛认可，但实际影响企业开展负责任创新的因素却依然模糊不清。针对这一问题，本研究基于企业行为理论，深入探讨了积极绩效反馈的强度和持续性对负责任创新的差异化影响，同时考察了管理者短视主义和高管团队年龄异质性对这一过程的调节作用。本研究选取了2011—2019年沪深两市A股上市公司作为研究样本，通过固定效应模型实证检验。结果发现：积极反馈强度与负责任创新之间存在倒U型关系，而积极反馈持续性对负责任创新有着显著的正向影响。此外，管理者短视主义削弱了积极反馈持续性对负责任创新的正向作用，而高管团队年龄异质性降低了积极绩效反馈强度和持续性对负责任创新的促进效果。上述结论经过稳健性和内生性检验后依然成立。这些发现不仅丰富了企业行为理论，揭示了积极绩效反馈的不同维度对负责任创新的差异化作用机制，也为推动我国企业积极参与负责任创新，实现可持续发展提供了重要的管理启示。

   In the background of self-reliance and self-improvement in science and technology, responsible innovation plays a crucial role in the sustainable development of enterprises and society. Although the importance of responsible innovation is widely recognized, the factors that affect the implementation of responsible innovation in enterprises are still unclear. Based on the behavioral theory of firms, this research explored the differentiated impact of the intensity and duration of positive performance feedback on responsible innovation, and the moderating effects of managerial myopia and TMT age heterogeneity. This paper selected Chinese A-share listed companies from 2011 to 2019 as the research sample and adopted the fixed effect model to test the research hypothesis. The results showed that the intensity of positive performance feedback has an inverted U-shaped impact on responsible innovation, while the duration of positive performance feedback has a positive impact on responsible innovation. Further analysis demonstrated that managerial myopia weakens the relationship between the duration of positive performance feedback and responsible innovation, while TMT age heterogeneity weakens both the relationships between the intensity and duration of positive performance feedback and responsible innovation. The conclusions are still valid after various robustness and endogeneity tests. These findings will not only enrich the behavioral theory of the firm, reveal the impact mechanisms of different dimensions of positive performance feedback on responsible innovation, but also provide important management implications for promoting Chinese enterprises to participate in responsible innovation and achieve sustainable development.
