Abstract:    Radical innovation is an effective way for firms to achieve technological excellence and gain competitive advantage. However, established studies have paid little attention to the issue of managerial behavior in radical innovation, especially in the lack of due exploration on the influence mechanism of culture on radical innovation behavior of corporate executives. Therefore, based on organizational learning and prospect theory, this paper constructed a moderated mediation model by exploring the influence of innovation quotient on radical innovation behavior of executives and its transmission mechanism, and analyzing the path regression coefficients to test the hypotheses item by item.First of all, this research has made the following findings: (1) innovation quotient can motivate executives to innovate and make breakthrough via exploratory learning, which in turn drives radical innovation behavior. The positive influence of knowledge and sharing on radical innovation has been generally recognized by academics, but the underlying logic of radical innovation has rarely been explored. Based on this, this study introduces exploratory learning as a mediating factor in exploring the interaction between innovation quotient and radical innovation behavior, and examines the underlying mechanism of innovation quotient driving radical innovation behavior. The findings of the study have some important theoretical value for a comprehensive study of radical innovation and also provide a new theoretical perspective for studying the awareness and understanding the potential learning processes that occur among groups. (2) Risk aversion plays a moderated role in the influence mechanism of innovation quotient on radical innovation behavior. Previous studies have lacked an examination of risk attitude elements when exploring the influencing factors of radical innovation behavior. This study introduces risk aversion into the research framework from the perspective of prospect theory and explores the moderating effect of risk attitude on the action mechanism of innovation quotient. The findings not only validate the association between risk aversion and exploratory learning for the first time, but also theoretically clarify the research boundary of the effect of innovation quotient on radical innovation behavior of executives.Then, this study has also obtained some practical insights as follows: (1) Nurturing innovation quotient is crucial as a management initiative that can facilitate radical innovation, and companies need to integrate relevant resources to combine nurturing innovation quotient and implementing innovation strategies. Therefore, managers need to create a high-quality exploratory learning environment to strengthen innovation capabilities through learning practices that lead to radical innovation. Moreover, managers need to realize that learning should not be limited to the individual level, but should be interactive and shared among groups. This paradigm change requires managers to abandon traditional perceptions and consider the implementation and recursive process of learning from the group and organizational levels, so as to improve the overall effectiveness of innovation breakthroughs. (2) Reduced risk aversion helps executives develop an inherent passion for innovation work, which in turn influences their radical innovation behavior. In particular, innovation breakthroughs do not happen overnight, but executives generally tend to choose less risk rather than benefit in the face of high cost, high risk and high uncertainty in the learning process. For this reason, in Chinese management practice, companies should pay special attention to risk avoidance and attitude change of executives. At the same time, executives should appropriately assess their self-competence and risk magnitude, and use organizational controls and incentives to reduce aversion and increase innovation input. 

Key words: innovation quotient, risk aversion, exploratory learning, radical innovation behavior
