NETWORK MEMORY: THE INFLUENCE OF PAST AND CURRENT NETWORKS ON PERFORMANCE.
研究意大利电视制作行业发现，当前的结构洞比过去的更有助于绩效，而过去的网络闭合比当前的更有效，说明结构洞和闭合在不同时间点各有价值。
Investigating the efficacy of two alternative network structures, closure and structural holes, from the contingent perspective of time, we connect past and current social structures to outcomes. We show that, in the Italian television production industry, current structural holes rather than past ones, but past closure rather than current closure, help current network performance. Thus, structural holes and closure are both valuable, but at different points in time.
