In 2009, many governments implemented austerity measures. This often resulted in restrictions on science funding, increasing competition for funds. Here, we study the allocation of funding across universities by using a competitiveness measure from complexity science based on the bipartite network of universities and scientific subjects. Drawing on a comprehensive data set of 43,430 UK-funded grants between 2006 and 2020, a period covering the onset and relaxation of austerity, we provide two main results. First, we find that the effect of austerity on university grant income depended on research competitiveness: highly competitive universities increased grant income under austerity, while low-ranked universities lost income. Then, we study the resilience of science to austerity exploiting the natural experiment arising from the 2015 UK general election, when austerity was relaxed unexpectedly. We discover that the resilience of researchers at less competitive universities was surprisingly high. The number and size of grant applications grew more after 2015 at less competitive universities, increasing their grant income. Overall, results show that our network-based measure is a better proxy for research competitiveness than aggregate grant income across scientific subjects.
2009年,许多政府实施了紧缩措施。这往往导致科学资金受到限制,资金竞争加剧。在此,我们基于大学与科学学科的二分网络,运用复杂性科学中的竞争力指标,研究了各大学之间的资金分配情况。利用2006年至2020年期间43430项由英国资助的拨款的综合数据集,该时期涵盖了紧缩措施的实施和放松阶段,我们得出了两个主要结果。首先,我们发现紧缩措施对大学拨款收入的影响取决于研究竞争力:竞争力强的大学在紧缩期间拨款收入增加,而排名靠后的大学收入减少。然后,我们利用2015年英国大选带来的自然实验研究科学对紧缩的恢复力,当时紧缩措施意外放松。我们发现竞争力较弱的大学的研究人员的恢复力出奇地高。2015年后,竞争力较弱的大学的拨款申请数量和规模增长得更多,增加了它们的拨款收入。总体而言,结果表明,与跨科学学科的总拨款收入相比,我们基于网络的指标是研究竞争力的更好代表。
