Building on recent efforts to bring a socio-political perspective to social capital research, we develop and test a multilevel framework that explains why middle managers who occupy brokerage positions differ in their ability and willingness to engage in entrepreneurial behavior. More specifically, we provide a contextualized understanding of the links among middle managers' brokerage, their political-support ties, and their personal initiative. Results derived from data on 383 middle managers and 72 top managers in 34 business units indicate that political-support ties with top managers strengthen the relationship between middle managers’ brokerage and personal initiative. However, this positive effect depends on the social capital resources available in the focal business unit. It is attenuated in business units with a supportive and trusting social context and amplified in business units with high levels of internal connectedness. By uncovering these incompatibilities and complementarities, our study demonstrates the value of accounting for different social capital configurations and the interplay of their inherent social capital resources when examining the effects of brokerage on corporate entrepreneurship.

基于最近将社会政治视角引入社会资本研究的努力，我们开发并测试了一个多层次框架，该框架解释了为什么担任经纪职位的中层管理人员在从事创业行为的能力和意愿方面存在差异。更具体地说，我们对中层管理人员的经纪业务、他们的政治支持关系和他们的个人主动性之间的联系提供了情境化的理解。从 34 个业务部门的 383 名中层管理人员和 72 名高层管理人员的数据得出的结果表明，与高层管理人员的政治支持关系加强了中层管理人员的经纪与个人主动性之间的关系。然而，这种积极影响取决于核心业务部门可用的社会资本资源。它在具有支持和信任的社会背景的业务单位中减弱，而在具有高度内部联系的业务单位中得到增强。通过揭示这些不相容性和互补性，我们的研究证明了在检查经纪业务对企业创业的影响时，考虑不同社会资本配置及其内在社会资本资源相互作用的价值。
