脆弱但有弹性:企业协作网络的适应性衰退

Fragile, yet resilient: Adaptive decline in a collaboration network of firms

Frank Schweitzer, Giona Casiraghi, Mario V. Tomasello, David Garcia

摘要:

企业合作网络的动态遵循一个成长和衰退的生命周期。这并不意味着它们也变得不那么有弹性。相反,衰退的合作网络可能仍然有能力减轻企业离开带来的冲击,并通过适应新的合作伙伴来弥补这些损失。为了证明这一点,我们分析了25年来6个不同行业的14500家公司的21500项研发合作。我们计算了企业离开网络的时间依赖概率,并模拟了退出级联,以确定预期的下降动态。然后,我们表明,偏离这些预期的结果是由于网络的自适应性,这减轻了下降。这些偏差可以用作网络弹性的度量。

英文摘要:

The dynamics of collaboration networks of firms follow a life-cycle of growth and decline. That does not imply they also become less resilient. Instead, declining collaboration networks may still have the ability to mitigate shocks from firms leaving, and to recover from these losses by adapting to new partners. To demonstrate this, we analyze 21.500 R\&D collaborations of 14.500 firms in six different industrial sectors over 25 years. We calculate time-dependent probabilities of firms leaving the network and simulate drop-out cascades, to determine the expected dynamics of decline. We then show that deviations from these expectations result from the adaptivity of the network, which mitigates the decline. These deviations can be used as a measure of network resilience.
