个体层次的角色外行为是通过群体互动和群体规范的作用在团队层次上突现，并形成一定的结构布局，从而影响团队创新绩效的。根据多层次理论，团队层次的行为结构通常用反映集中趋势的均值法与反映离散程度的极值法和方差法等几种操作化方法来表示。通过对59个研发团队的实地调研，发现帮助和建言这两种个体层次的角色外行为同时以组成和汇编的形式在团队层次突现，个体帮助行为在团队内的平均水平与团队创新绩效显著相关，而个体建言行为在团队内的最优水平对团队创新绩效的影响最大，同时，个体帮助行为在团队内的最低水平和个体建言行为在团队内的平均水平也与团队创新绩效显著相关。

英文摘要：

In the process of group interaction and by the constraint of group norms, individual extra-role behaviors emerge at team-level and form a certain construct, thereby influencing team innovation performance. According to multilevel theory, team-level behavioral structures are usually operationalized by mean, which reflects central tendency, and by maximum, minimum and variance, which reflect dispersion. Through the empirical study of 59 R＆D teams, it was found that individual helping and voice extra-role behaviors aggregated via both composition and compilation forms of emergence. The mean level of individual helping behavior and the maximum level of individual voice behavior had the highest correlation with team innovation performance. The minimum level of individual helping behavior and the mean level of individual voice behavior were also significantly correlated with team innovation performance.
