摘　　要：隔网对抗项目战术行为观察和评估指标选取普遍以"1分"为单位,忽略了隔网项目计分体系的分层结构和时序特征,加之一场比赛分数有限,因此出现了分与分之间的区分不够明显,比赛中技战术的细微差别难以评价等问题。通过文献资料法、逻辑分析法对隔网项目计分体系特征进行梳理,并对评价单位加以提炼,经过逻辑推理和分析,提出"1分球竞技效率值"的概念和推导公式。"1分球竞技效率值"是指在对隔网项目进行比赛分析评价时,所选择的最小评价单位,通过1分球的竞技效率值可以把技术评价与比赛获胜之间构建关联。1分球竞技效率值推导公式充分体现了隔网项目计分体系的分层结构和时序特征。经过对乒乓球、羽毛球和网球项目的回归检验,得出:1分球竞技效率值的提出,增加了分与分的区分度,从而能够确保比赛的评价体系的完整性,使技战术的评估更加科学、准确。The observation and evaluation indicators of tactical behavior in net ball games generally select＂1 point＂as the unit,which neglects the hierarchical structure and time-sequence characteristics of scoring system in net ball games. A game score is limited which caused problems such as that the distinction between point and point is not obvious,and it is hard to evaluate subtle differences in techniques and tactics of games. This study combed the scoring system characteristics in net ball games,selected evaluation indicators,and provided the concept and derived equation of＂competitive efficient value one point＂. The＂competitive efficient value of one point＂is the minimum unit to evaluate net ball games,it can construct the correlation between technique evaluation and competition result,and it fully reflects the hierarchical structure and time-sequence characteristics of scoring system in net ball games. The regression test results of table tennis,badminton and tennis showed that＂competitive efficient value of one point＂increases the distinction degree between point and point to ensure the integrity of the evaluation system of games,and to make the evaluation of techniques and tactics more scientific and accurate.
