Entrepreneurial leadership is an effective leadership style that promotes an organization's competitive advantage and sustainable development.In modern organizations,entrepreneurial leaders play important roles in organiza-tional growth and development.Recent research has focused on the effects of entrepreneurial leadership on entrepreneurial performance,organizational resilience,innovation,and knowledge management.However,these studies have not con-sidered the decision-making logics of leaders and have mainly hypothesized them as antecedents of organizational be-haviors,rather than considering them as moderators.Based on the theory of effectuation,this study presents a dual path model to examine the dual effects of entrepre-neurial leadership,considering the moderating effects of causation and effectuation decision-making logics.A two-wave longitudinal survey was conducted,with a two-month interval between the waves.The first wave collected data on partici-pants'demographics,organizational information,perceptions of entrepreneurial leadership,causation decision-making logic,and effectuation decision-making logic.Two months later,the second wave collected data on entrepreneurial learning,entrepreneurial improvisation,and entrepreneurial performance.Path analysis was used to test the hypotheses,and the results,based on 210 valid questionnaires,demonstrated that entrepreneurial leadership had a positive indirect effect on entrepreneurial performance through entrepreneurial learning,moderated by causation decision-making logic.Specifically,when leaders exhibited high causation decision-making logic,the positive indirect effect of entrepreneurial leadership on entrepreneurial performance through entrepreneurial learning was stronger.Moreover,entrepreneurial leadership also promoted entrepreneurial performance through entrepreneurial improvisation,moderated by effectuation decision-making logic.Specifically,when leaders exhibited high effectuation decision-making logic,the positive indirect effect of entrepreneurial leadership on entrepreneurial performance through entrepreneurial improvisation was stronger.Furthermore,effectuation decision-making logic was found to moderate the indirect effect of entrepreneurial leadership on entrepreneurial performance through entrepreneurial learning.These findings have theoretical and practical implications.The study contributes to a comprehensive understanding of the effects of entrepreneurial leadership by examining the dual paths of entrepreneurial learning and improvisation and the moderating roles of effectuation and causation decision-making logics.The application of effectuation theory and the consideration of decision-making logics as moderators address the need for more research in this area.From a practical perspective,attention should be given to entrepreneurial leadership and their decision-making logics.Leaders should adopt appropriate decision-making logics at different stages of enterprise development and in different environments,while focusing on organizational behaviors that promote entrepreneurial performance.
