论文摘要
公司协作网络的动态遵循生命周期的增长和下降。这并不意味着它们也变得越来越弹性。取而代之的是，下降的协作网络可能仍然能够减轻公司离开公司的冲击，并通过适应新合作伙伴来从这些损失中恢复过来。为了证明这一点，我们分析了25年内六个不同工业领域的14.500家公司的21.500 R \＆d合作。我们计算离开网络并模拟辍学级联的公司的时间依赖性概率，以确定预期的下降动态。然后，我们表明，与这些期望的偏差源于网络的适应性，从而减轻了下降。这些偏差可以用作衡量网络弹性的量度。
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.
