摘要
以往的研究强调，裁判偏见是导致足球主场优势的潜在因素。为了揭示裁判偏见的重要性，我们利用 2009 年至 2019 年间 16 个国家国内顶级联赛的数据，利用视频助理裁判（VAR）的交错实施来估计客观审查系统对足球主场优势的影响。令人惊讶的是，尽管越位和黄牌总数有所减少，但 VAR 的实施对主场优势和各种关键比赛统计数据的影响微乎其微。这些结果提供了有关裁判偏见可能导致主场优势的机制的提示性证据，并强调了范围可能如何限制一般审查程序的有效性。
Video assistant referee and home field advantage: Implications for referee bias
Previous research has highlighted referee bias as a potential contributor to home field advantage in soccer. In order to shed light on the importance of referee bias, we exploit the staggered implementation of Video Assistant Referee (VAR) using data from the top domestic league in 16 countries between 2009 and 2019 to estimate the effect of objective review systems on home field advantage in soccer. Surprisingly, the implementation of VAR had negligible effects on home field advantage and various crucial match statistics despite decreased total offsides and yellow cards. These results provide suggestive evidence regarding the mechanisms through which referee bias might contribute to home field advantage and highlight how scope may limit the effectiveness of review processes in general.
