二元奥林匹克竞赛的引力模型
Gravity model for dyadic Olympic competitions
摘要：
在奥林匹克运动会上，职业运动员代表他们的国家参加比赛，而不考虑经济、政治和文化的差异。在这项研究中，我们应用引力模型来观察特征，代表在夏季奥运会上直接竞争的国家之间的距离。我们使用由1952年至2016年奥运会奖牌获得国组成的二元数据。为了比较冷战期间和之后的动态变化，我们将数据分为两个时间段（1952-1988和1992-2016）。本文的研究与以往的研究不同之处在于，我们新引入了引力模型在奥运会动态观测中的应用。我们的研究结果表明，在整个研究期间，在奥运会决赛中相互竞争的国家在经济规模上往往相似。冷战后，竞争更频繁的国家对往往在遗传起源上相似。
英文摘要：
In the Olympic Games, professional athletes representing their nations compete regardless of economic, political and cultural differences. In this study, we apply gravity model to observe characteristics, represented by distances among nations that directly compete against one another in the Summer Olympics. We use dyadic data consisting of medal winning nations in the Olympic Games from 1952 to 2016. To compare how the dynamics changed during and after the Cold War period, we partitioned our data into two time periods (1952-1988 and 1992-2016). Our research is distinguishable from previous studies in that we newly introduce application of gravity model in observing the dynamics of the Olympic Games. Our results show that for the entire study period, countries that engaged each other in competition in the finals of an Olympic event tend to be similar in economic size. After the Cold War, country pairs that compete more frequently tend to be similar in genetic origin.
