Knowledge Portfolios and The Organization of Innovation Networks
用一个简单模型证明，仅假设企业间需要一定知识共同性才能成功结盟，就能产生小世界结构、链接分布偏斜等战略联盟网络特征，无需依赖社会资本理论。
Properties of strategic alliance networks, such as small world structures, skewed link distributions, and patterns of repeated tie occurrences, are often explained in terms of social capital theories. A simple model shows how merely assuming that firms must have a certain degree of commonality in their knowledge to have a successful alliance is enough to produce the above features, without recourse to social capital at all.
