中文摘要：

团队异质性的平衡性是指团队中异质性属性的相对分布情况,是一个从不平衡到平衡的连续谱概念。作为对团队构成维度的补充,本研究探究其如何通过团队信息深化施加影响于团队创造力。通过对浙江理工大学451名学生的团队实验研究,得出结论认为：团队知识异质性的平衡性能够积极影响团队创造力,且团队信息深化在这一过程中起中介作用,性别异质性的平衡性与团队创造力之间的关系不显著。这一研究结果将有助于打开团队构成和团队创造力研究的新局面。

英文摘要：

The increasing use of team as a basic operation unit of organizations makes team creativity a popular research topic. Team diversity is one of the most important factors of team creativity. the extant understanding of team diversity is focused on absolute distribution of diversity, while comparative distribution of diversity has rarely been studied. This paper proposes a new concept – the balance of team diversity, which is the comparative distribution of the team members＇ diverse characters. This concept helps to reveal the comparative strength of team diversity which is ignored by previous studies, and thus contributes to the research of relationship between team diversity and team creativity. This paper studies the effect of the balance of knowledge diversity and gender diversity on team creativity. We propose that the balance of team knowledge and gender diversity would positively affect team information elaboration and team creativity. Furthermore, team information elaboration mediates the relationship between the balance of team diversity and team creativity.We collected data from 80 teams, 451 students in Zhe Jiang Sci-Tech University via lab experiments. The task is designing the advertising video for Chinese government on World Expo. The experiment lasted one hour. Each team needs to put forward a video plan（between 200~500 words）. Each team was made up of 4~7 persons and most of teams were made up of 6 persons. We designed a formula to calculate balance of team diversity. Team creativity was graded by three independent experts with scope from 1 to 10（1 stands for least creative and 10 stands for most creative）.Team information elaboration was measured with a scale of 4 questions developed by Kearney, Gebert and Voelpel（2009）. The main results are summarized as follows： a） Balance of team knowledge diversity was positively related to team creativity, while the relationship between balance of team gender diversity and team creativity was not significant. b） Balance of team knowledge
