大学和高等教育机构是国家基础设施和声望的组成部分。随着学术研究越来越多地受益于国际交流与合作，许多大学增加了投资，以改善和实现其全球连通性。然而，大学绩效与其全球物理连通性的关系尚未得到详细探讨。据我们所知，我们进行了第一次大规模的数据驱动分析，以确定大学的相对排名表现与其通过航空运输网络的全球连通性之间是否存在相关性。结果表明，当地进入全球枢纽（以航空运输网络介数衡量）与排名增长呈强烈正相关（不同模型的统计显著性范围在5%至1%之间）。我们还发现，当地机场的总飞行路径（度）和容量（加权度）对大学排名没有影响，进一步表明全球连接距离比航班连接容量更重要。我们还研究了当地城市经济发展作为混杂变量的影响，没有观察到任何影响，表明进入全球交通枢纽的机会超过了经济表现作为大学排名的决定因素。这项研究的影响是，我们已经确定了全球连通性的中心地位的重要性，因此，建立了初步的证据，进一步探索大学排名和区域投资政策之间的潜在联系，以改善全球连通性。
Universities and higher education institutions form an integral part of the national infrastructure and prestige. As academic research benefits increasingly from international exchange and cooperation, many universities have increased investment in improving and enabling their global connectivity. Yet, the relationship of university performance and its global physical connectedness has not been explored in detail. We conduct, to our knowledge, the first large-scale data-driven analysis into whether there is a correlation between university relative ranking performance and its global connectivity via the air transport network. The results show that local access to global hubs (as measured by air transport network betweenness) strongly and positively correlates with the ranking growth (statistical significance in different models ranges between 5% and 1% level). We also found that the local airport’s aggregate flight paths (degree) and capacity (weighted degree) has no effect on university ranking, further showing that global connectivity distance is more important than the capacity of flight connections. We also examined the effect of local city economic development as a confounding variable and no effect was observed suggesting that access to global transportation hubs outweighs economic performance as a determinant of university ranking. The impact of this research is that we have determined the importance of the centrality of global connectivity and, hence, established initial evidence for further exploring potential connections between university ranking and regional investment policies on improving global connectivity.
