Too much of a good thing? Network brokerage within and between regions and innovation performance
研究了区域内和区域间网络中介对区域创新绩效的多层次影响，发现平衡内部中介与外部边界跨越能提升创新绩效，对区域发展政策制定者有用。
The paper offers a multilevel understanding of the effect of brokerage on regional innovation. We develop a typology of regional networks based on the extent to which the inventors of a region connect the otherwise disconnected group of local inventors (internal brokerage) or connect the local network with other regions (external boundary-spanning). Using data on regional innovation performance and co-inventing networks within and between US metropolitan statistical areas (MSAs) between 2000 and 2014, we show that configurations balancing high (low) internal brokerage and low (high) external boundary-spanning lead to higher innovation performance than those where brokerage occurs at both levels of analysis.
