摘　　要：中职篮历经20年的发展,在不断修改革新的赛制下,联赛的观赏性和竞技水平大幅度提高,比赛的悬念加大,不确定性增加,竞争格局也向着平衡方向发展。其中,赛制流变过程中出现的实施-取消反复现象,是中职篮自身完善的必经过程。本研究运用文献资料调研、专家访谈、数理统计、香农熵分析对中职篮2005—2015年赛制的变化与其影响进行梳理和探讨,通过引入香农熵值对2005—2015年联赛竞争格局平衡性进行分析,发现在过去10年中,中职篮竞争性快速提高,"扩军"、"亚洲外援政策"、"末节单外援"等赛制的变化对中职篮竞争平衡有积极作用,同时,近3个赛季出现强弱分化的特殊现象,为未来赛制的调整指明方向。With two decades development and the constant renewal of the competition system,the enjoyment and competitive level of CBA league are significantly raised.Games with more suspense and uncertainty,the competition of CBA league makes more improvement.Furthermore,the repetition of ＂execute-cancel＂phenomenon is an inevitable process for completing CBA league itself.In this paper,we use literature,experts interview,mathematical statistics,to comb and discuss the changes in competition system of CBA league in 2005—2015.By introducing the Shannon entropy to analyse the balance of the league competition in last decade,we find out that the league＇s competitiveness increases rapidly,and several changes of competition rules like ＂arms expansion＂,＂Asian import policy＂and ＂last quarter with singer import policy＂make positive contribution to the competitive balance.At the same time,the polarization of strong colony and weak colony in recent three seasons indicates a clear direction for the adjustment in the future.
