基于SCP模型的世界男子和女子职业网球竞争平衡差异研究

Research of Competitive Balance Difference between ATP and WTA by using Scp-based Model

基于经济学的结构-行为-绩效(Structure-Conduct-Performance)模型,对世界男子和女子职业网坛竞争力平衡差异进行分析。在衡量特定赛事男子和女子职业网球竞争性平衡差异时,引用了"抢七"和"最少获胜盘"两项数据,结果显示,男子比赛更具竞争性;而在比较跨赛季男子和女子比赛竞争性平衡差异时,研究了ATP和WTA年终排名及4大满贯冠军得主两项指标,结果显示,在年终排名这一指标上,男子和女子比赛竞争性平衡不存在差异;而大满贯冠军得主数据则显示,女子比赛竞争性强于男子。
