本研究目的為比較國內、外職業及青少年選手在2015 年三大賽事（澳、法、溫網）各技術因子影響比賽勝負之關聯程度。研究對象為國外職業與青少年前32 強選手，以及國內盧彥勳、吳東霖及駱建勛選手，資料有62 個勝場、11 個勝盤及10 個變項，採用LabView 程式語言軟體進行灰色關聯度分析。研究結果得知：一、國內、外職業選手在三大賽事整體各技術因子對勝負的關聯度，最高因子皆為第一發贏球率，最低為雙發失誤；二、國內、外青少年選手在三大賽事整體各技術因子對勝負的關聯度，國外選手在澳網最高因子為：第一發進球率，最低為網前得分率；在法網最高為：接發球勝率，最低為雙發失誤；在溫網最高為：第一發贏球率，最低為雙發失誤；國內選手最高因子為：第一發贏球率，最低為致勝球。本研究結論：國內、外職業選手方面，在發球局表現對於勝負的關聯度均高於接發球局，另外，國外選手強調擊球的破壞力比穩定性更重要；國內、外青少年選手方面，國內選手在發球上，應計畫有效取分的觀念，在接發球上，應加強反守為攻的能力，並在擊球的心態上提高侵略性。

This study aimed to compare the relationships among various technical factors that affect the match results of professional and junior players in three major tennis tournaments, including the Australian Open, the French Open, and the Wimbledon Championships in 2015. The participants in this study were top 32 foreign, professional, junior tennis players from each tournament, as well as 3 Taiwanese tennis players, including Yen-Hsun Lu, Tung- Lin Wu, and Chien-Hsun Lo. The data in this study included 62 games won, 11 sets won, and 10 variables. The software package LabVIEW was employed to perform the grey relational analysis on the data. The findings were as follows: (1) Among the technical factors that affect match results of local and foreign professional players in the three major tournaments, the factor with the highest correlation to the match results was the first serve win percentage, whereas the percentage of double faults had the lowest correlation to the match results. (2) The factor with the highest correlation to the match results of foreign players was the first serve win percentage; whereas the percentage of net points won had the lowest correlation to the match results. In the French Open, the factor with the highest correlation to the match results was the percentage of receiving points won, whereas the percentage of double faults had the lowest correlation to the match results. In the Wimbledon Championships, the factor with the highest correlation to the match results was the first serve win percentage, whereas the factor with the lowest correlation to the match results was the percentage of double faults. Among local players, the factor with the highest correlation to the match results was the first serve win percentage, whereas the factor with the lowest correlation to the match results was percentage of winners. This study concluded that among local and foreign professional players, serve performance had a higher correlation to match results than the return of serve. Moreover, foreign players emphasized that the power of shots were more important than the stability of shots. The results suggest that local players should develop effective ideas to win points on the serve, and enhance their ability to turn defense into attack during a return of serve, and increase power when hitting the ball.
