摘要

主场优势的存在是所有体育运动中最持久的经验模式之一。然而，解释其强度和持久性的机制在很大程度上仍然是一个谜，因为在统计鉴定方面存在众所周知的挑战。我们使用2020-2021年nba常规赛期间的出勤限制作为一种工具，以确定球迷和观众规模对主场优势的影响。我们发现，当有球迷在场时，主队的平均胜率为[公式:见文本]，而当没有球迷在场时，主队的平均胜率为[公式:见文本]。这相当于在一个常规赛中多赢了大约2.2场主场比赛。在固定效应工具变量回归模型中，我们估计额外一千名球迷对主场优势的边际效应为[公式:见文本]点。我们的结论是，仅仅是主场球迷的存在，就能解释比之前认为的更大份额的主场优势。

A Mere Fan Effect on Home-Court Advantage

The existence of a home-court advantage is one of the most durable empirical patterns in all of sports. Yet, the mechanisms explaining its strength and persistence remain a mystery in large part because of well-known challenges with statistical identification. We use attendance restrictions in place during the 2020–2021 National Basketball Association regular season as an instrument in order to identify the effect of fans and crowd size on home-court advantage. We show that home teams win by [Formula: see text] points, on average, when fans are present at games compared with [Formula: see text] points when no fans are present. This equates to winning approximately 2.2 additional home games over the course of a regular season. In fixed effects instrumental variables regression models, we estimate that the marginal effect of an additional one thousand fans on home-court advantage is [Formula: see text] points. We conclude that the mere presence of home fans, on its own, explains a larger share of home-court advantage than previously thought.
