目的：中華男籃和日本男籃曾經在比賽中勢均力敵。本研究旨在探討日本男籃是如何將競爭力提升至奧運的級別，提供中華男籃作為學習或效仿之借鏡。方法：本研究以中華男籃和日本男籃球隊為個案，收集關於球員身高、體重和年齡的數據作為評估指標，並採用資料視覺化進行數據分析，透過三維策略矩陣建構選拔評估模式，比較兩支球隊球員的屬性。結果：相較於10年前，中華隊與日本隊的球員組成差距日益擴大，日本隊的混血和歸化球員比中華隊多出許多，整體條件優於中華隊。結論：日本隊相當重視混血和歸化球員的養成，球員具備身體優勢是球隊競爭力至關重要的因素。最後，建議鋒線球員可選用具有身體優勢的混血與歸化球員。創新性：1.使用資料視覺化方法來比較球員的數據。2.採用三維策略矩陣來評估球員的屬性。

Purpose: The current study investigated the historical competitiveness between the Chinese Taipei and Japan men's basketball teams. The study investigated how the Japan team has increased its competitiveness to Olympic levels and highlighted the valuable lessons that the Chinese Taipei team can draw from this change. Methods: This study focused on the Chinese Taipei and Japan men's basketball teams. Data regarding player height, weight, and age were collected as evaluation indicators. Data visualization was used for a data analysis, and three-dimensional matrices were used to demonstrate the attributes of each player on the investigated teams. Results: A notable gap has developed between the Chinese Taipei and Japan men's basketball teams between 2013 and 2022. Compared with the Chinese Taipei team, the Japan team has numerous mixed-race and naturalized players, and the overall condition of the players is more favorable. Conclusion: The Japan team has focused on gaining mixed-race and naturalized players. The physical attributes of players are an essential determinant of a team's competitiveness. Mixed-race and naturalized players with notable physical attributes should be selected for the forward group within a basketball team. Originality/value:1. Data visualization was used to compare the data of players. 2. A three-dimensional strategy matrix was used to evaluate the attributes of players.
