NBA data

The sample for this study is composed of NBA players from the 1999–2000 season through the 2015–2016 season. Data on the ethnicities of NBA players was manually collected by searching websites such as Wikipedia, Facebook, Google, and Baidu Encyclopedia; where it was impossible to make this judgment based on player data, players’ pictures published on the Basketball Reference website (http://www.basketball-reference.com) were examined to determine ethnicity (Wallace, 1988). Player salaries were collected from the ESPN website (http://www.espn.com/nba/salaries); player characteristics and technical data come from the ESPN website and the Basketball Reference website. Players who changed teams within a season were eliminated from the sample, as were players who made less than two appearances on the court within a season.

本研究的样本涵盖1999-2000赛季至2015-2016赛季的NBA球员。NBA球员的种族信息通过检索维基百科、Facebook、谷歌、百度百科等网站手动采集；若无法通过球员公开资料判定种族，则参考篮球参考网站（Basketball Reference，http://www.basketball-reference.com）发布的球员照片进行种族判定（Wallace，1988）。球员薪资数据采集自ESPN官网（ESPN，http://www.espn.com/nba/salaries）；球员个人特征与技术统计数据来源于ESPN官网及篮球参考网站。本研究剔除了单赛季内更换球队的球员，以及单赛季出场次数不足2次的球员。
