本研究採標記分析法，以2005年及2006年全國第一次羽球排名賽女子單打前八強競賽為研究內容，探討不同計分制度對羽球女子單打競賽表現之影響。以不同計分制度為自變項，依變項包括擊球拍數、拉鋸時間、每拍反應時間、發球型態、得分型態及失誤型態，以獨立樣本t考驗分析時間因素的影響及百分比同質性卡方考驗分析技術型態的影響，顯著水準設定為α= .05。本研究的結果為：1.新制每回合平均擊球拍數為7.76±1. 33拍顯著多於舊制的6.58±0.75拍；2.新制每回合拉鋸時間為8.12±1. 59秒顯著多於舊制的6.66±0.80秒；3.新制每拍反應時間為1.06±0.06秒，舊制為1.05±0.08秒，兩者差異未達顯著水準；4.新制發球型態選擇發長球的百分比為74.83%顯著高於舊制的56.86%，選擇發短球的百分比為20.82%顯著低於舊制的38 .1%；5.新制得分型態在直接得分的百分比為23.57%顯著高於舊制的14.85%，在對方失誤得分的百分比為75.06%顯著低於舊制的84.03%；6.新舊制失誤型態在受迫及非受迫失誤方面，皆無顯著差異。結論：本研究認為在訓練上可配合新制的實施，參考每回合拉鉅時間來設定訓練強度，並透過技術的分析，藉由球路模擬來訓練選手攻防對峙的技術，以及培養轉守為攻的積極意識。未來能進一步針對世界級選手的競賽資料進行分析，了解國際羽球競賽的新趨勢，以供羽球訓練及未來研究參考。

　　The purpose of this study was to compare the competitive performances of badminton women's singles between the two scoring systems using notational analysis. A total of 10 matches including the matches from the quarter-finals of the 2005-2006 first national tournament were video taped. Scoring systems were the independent variables, and the dependent variables including shots per rally, time per rally, time per shot, the shot selections of serve, the categories of winning, and the categories of losing. Independent t test, and test of homogeneity of proportions were used for analysis, the significant level set at = .05. The results showed that the significant difference between the two scoring systems were the mean number of shots per rally (7.76s±1.33, 3×21 format vs. 6.58s±0.75, 3×11 format), the mean time of each rally (8.12s±1.59, 3×21 vs. 6.66s±0.8, 3×11), the shot selections of serve (Deep: 74.83%, 3×21 vs. 56.86%, 3×11. Short: 20.82%, 3×21 vs. 38.1%, 3×11), and the categories of winning (Direct winning: 23.57%, 3×21 vs. 14.85%, 3×11. Error winning: 75.06%, 3×21 vs. 84.03%, 3×11). Based on the finding in this research, suggestions for badminton players' training and further studies were proposed.
