Social Origins of Great Strategies
用网络理论解释伟大战略的社会起源，认为社会网络中连接多个群体的中间人因知识流动优势更可能发现和制定新战略。
We use network theory to define the social origins of great strategies. Our argument proceeds in four steps: (1) The bridge and cluster structure of social networks is a proxy indicator of variation in knowledge and practice (homogeneity within clusters, heterogeneity between); (2) people with strong connections to multiple clusters (network brokers) have breadth, timing, and arbitrage advantages in moving knowledge/practice from clusters where it is a commodity into clusters where it is valuable. (3) New strategy is a new perspective on, or new combination of, prior knowledge/practice; so (4) network brokers have a competitive advantage in detecting and developing new strategies, a subset of which are great strategies.
