职业体育竞争平衡研究

Professional sports competition balance

职业体育经济学的一个重要的特征是,竞赛产品的质量与竞赛结果的不确定性成正比。职业联盟内各球队间的竞争平衡决定竞赛结果的不确定性程度。衡量职业体育竞争平衡的变量包括胜率标准差,竞争平衡系数和HHI指数。可能影响竞争平衡的制度因素包括逆向选秀、工资封顶、奢侈税和收入分享等,但效果并未完全得到实证支持。

One of the key features of the professional sports economics study is that the quality of the competition products is proportional to the uncertainty of the competition results.The competition balance among the different teams in the professional leagues determines the uncertainty degree of the competition results.The variables measuring the professional sports competition balance include standard deviation of winning rate,competition balance index and HHI index.The system factors influencing the competition balance include reverse talent show,salary caps,luxury tax and income share but the effects are not verified.
