10123Plural leadership is an important development trend of the group leadership mode. At present, a large quantity of literature has conducted theoretical and empirical research on plural leadership, among which, the most key concern is the leadership effectiveness of plural leadership. From the early exploration of relationship between two variables to the introduction of mediating mechanisms and moderator variables that influence the strength or direction of this relationship, academics have conducted in-depth studies. However, there are still different views around the current research on the effectiveness of plural leadership. For example, bounded by a particular research design, the analysis conclusions on the relationship between plural leadership and leadership effectiveness have different perspectives on the strength, direction and statistical significance of correlations, and the increase in the number of related studies in recent years has exacerbated these divergences. We believe that there are two potential reasons to explain these inconsistencies. First, previous quantitative literature that analyzes these differences by the meta-analysis method tend to mix different types of plural leadership concepts and fail to truly reflect the effectiveness of plural leadership. Second, current empirical literature that adopts different indicators to measure leadership effectiveness and lack uniformity for various research situations and data measurement methods, may also lead to different leadership effectiveness outcomes of plural leadership. In order to avoid the above two problems, drawing on the concept and classification of plural leadership constructed by Denis, et al.（2001, 2012）based on group leadership, this study examines the effect of plural leadership on leadership effectiveness and the moderator effects of situational factors and methodological factors through the meta-analysis method, then explores in depth the inconsistent reasons of this relationship between plural leadership and leadership effectiveness in previous studies. Four inclusion criteria are used to collect samples from the eastern and western resources. First, the research must include relevant variables for plural leadership and leadership effectiveness. Second, we only focus on empirical research, excluding review articles, case studies and other research. Third, effect statistics between two variables must be reported in the study. Fourth, if the same sample is repeatedly published in different studies, we only select larger sample size and more detailed studies in the present study. Based on 60 independent research samples from 1991 to 2017 years that are finally included, we code the samples and resolve the disagreement through discussion or other means, then analyze the data by utilizing the Comprehensive Meta-Analysis（CMA）Version 2 program. Meta-analysis results show that: plural leadership can effectively promote leadership effectiveness; in terms of performance improvement, plural leadership can significantly improve psychological and behavioral processes; moreover, shared and relational leadership focuses on promoting psychological and behavioral processes, while distributed and collective leadership contributes to performance improvement; when team average tenure, cultural differences and leadership measures change, the effect of plural leadership on leadership effectiveness will vary, but changes in team types and data attributes do not affect the impact of plural leadership on leadership effectiveness. The above conclusions clarify and enrich the existing research results on the link between plural leadership and leadership effectiveness. Moreover, it is of great practical significance for enterprises seeking to transform the leadership model to successfully implement plural leadership among team members, and to guide the contingency implementation of plural leadership management methods based on their own characteristics, team mission requirements and organizational environment choices.
