The effectiveness of entrepreneurial leadership (EL) at different levels has been widely recognized by scholars who have carried out substantial exploration; however, the empirical studies on the effectiveness of EL are scattered and their results are mixed. This study aims to organize these findings, advance knowledge about the multilevel effectiveness of EL and clarify the heterogeneity in the relationship between EL and effectiveness outcomes. Based on a systematic review of the extant literature and the construction of an integrated framework, this study examines the influence of EL on effectiveness outcomes at multiple levels and the moderators of this relationship through meta-analysis of 35 empirical studies including 35 independent samples. The results show that EL can improve effectiveness outcomes at different levels of organization, team and individual; cultural context obviously moderates this relationship, whereas the moderating effects of enterprise type and EL measure are all not significant. This study helps to determine the specific association of EL with effectiveness outcomes at different levels, and identify important factors influencing this relationship, which broadens the understanding of leadership effectiveness and provides certain value for enterprises to give full play to the role of EL at all levels.

企业家领导力的多层次有效性：荟萃分析

不同层次的创业领导力（EL）的有效性得到了学者的广泛认可，并进行了实质性的探索；然而，关于 EL 有效性的实证研究比较分散，结果参差不齐。本研究旨在整理这些发现，推进关于 EL 多层次有效性的知识，并阐明 EL 与有效性结果之间关系的异质性。基于对现有文献的系统回顾和综合框架的构建，本研究通过对包括 35 个独立样本在内的 35 项实证研究的荟萃分析，检验了 EL 对多层次有效性结果的影响以及这种关系的调节因素。结果表明，EL 可以提高组织不同级别的有效性结果，团队和个人；文化背景明显调节了这种关系，而企业类型和EL度量的调节作用均不显着。本研究有助于确定EL与不同层次效能结果的具体关联，并找出影响这种关系的重要因素，拓宽了对领导效能的理解，为企业在各级充分发挥EL的作用提供了一定的价值。 .
