A Multilevel Model of Group Social Capital
提出群体社会资本概念，即群体成员通过社会关系获得的资源集合，认为这些资源能提升群体有效性，并构建了一个多层次、多维度的模型来解释资源流动渠道及其最优平衡。
We introduce the concept of group social capital—the set of resources made available to a group through members' social relationships within the social structure of the group and in the broader formal and informal structure of the organization. We argue that greater group social capital resources lead to greater group effectiveness and that there are many different conduits through which group social capital resources flow. We present a multilevel, multidimensional model arguing that an optimal balance of all these conduits maximizes group social capital resources and group effectiveness.
