英文文献摘要：
External knowledge acquisition represents a precondition for firms’ competitive advantage. However, young firms find it particularly difficult to gain access to external sources of knowledge: young firms suffer from a liability of newness by exhibiting significantly lower propensities to invest in external R&D than their older counterparts. We explore the role of geographically bound social capital in moderating this liability. By employing a Nested Logit approach, our findings show that geographically bound social capital moderates the liability of newness related to R&D acquisition, suggesting that the liability exists only in regions associated with low levels of social capital.

外部知识获取是企业获得竞争优势的前提。然而，年轻的公司发现它很难获得外部的知识来源:年轻的公司由于表现出明显较低的倾向于投资外部研发比他们的老对手遭受了新事物的负债。我们探讨地理上受限制的社会资本在缓和这一责任中的作用。通过使用一个嵌套的Logit方法，我们的研究结果表明，地理上受限制的社会资本调节了与研发购买相关的新产品负债，这表明这种负债只存在于与低社会资本水平相关的地区。
