職業籃球效率值與聯盟表現的關聯性研究-東亞與美國職業籃球聯盟為例

本研究旨在探討職業籃球球員效率值與球隊之間的關係，並以東亞國家中的中國男子籃球職業聯賽(Chinese Basketball Association, CBA)、臺灣超級籃球聯賽(Super Basketball League, SBL與籃球體系發展最完整的國家美國國家籃球協會(National Basketball Association, NBA)為研究對象。首先，以球員在職業籃球聯賽的數據中解釋效率值(EFF值)的價值，接著蒐集2014-2015的賽季數據樣本，透過獨立樣本t檢定，希冀從NBA跟CBA、SBL的比較，我們從不同區域的聯賽中來探討EFF值，透過統計檢定判斷是否有顯著性，獨立樣本t檢定結果皆發現三個聯盟的比較皆有顯著性，其中以NBA與SBL的組合顯著性最為明顯。本文貢獻在於導入研究假說後，以標竿指標去分析探討三個聯盟的顯著性，其中標竿指標分為十一個項目，這些項目分別代表球員不同表現的效率，分別為進攻、防守、季後賽與冠軍賽的效率等，以標竿指標代表聯盟不同項目的強度，最後導入t檢定分析NBA、CBA、SBL的聯盟效率值落差為本論文的研究價值。以預期差異來說，聯盟效率值整體強度應是NBA>CBA>SBL，但是針對三個聯盟透過標竿指標區分為多項分類後，再以獨立樣本t檢定分析發現很多項目是CBA>NBA，從標竿指標探討出CBA外籍球員效率值過高所造成的差異性例如標竿指標中的全球員效率值。其中也有因為CBA外籍球員指數過高與NBA造成無顯著性，例如晉級季後賽與冠軍賽效率值。整體而言以不同標竿指標所計算之效率值中，CBA與NBA差距並不大，但是兩者都與SBL有很大的差異性。

This study is comparing the professional basketball player's efficiency value (EFF value) of the two associations, Chinese Basketball Association (CBA) and Super Basketball League (SBL) with National Basketball Association (NBA) as research object. First of all, we calculate the EFF value of different player on each professional basketball league. Second, we find the significant different of the EFF value between NBA, CBA and SBL with seasonal data in 2014 to 2015 using independent-sample t test, Furthermore, we find the significance different is more obvious between the part of NBA and SBL. Contribution of this paper is to construct the different of target indicators testing 8 hypotheses, which the target indicators is divided into eleven projects, such as offensive, defense, playoffs and championship efficiency. The difference is expected that the EFF value should be NBA more than CBA, and CBA more than SBL. However, the three leagues through the target indicators is divided into a number of categories, and then analysis with independent t-test, found that many projects are CBA more than NBA. The reason why CBA is significant more than NBA is that the efficiency of foreign players is too high, so that it causes the difference. However, the different of EFF value between CBA and NBA is not significant in the playoffs and finals. In general, through the EFF value of different type of target indicators, CBA and NBA have no significance. However, both of them are better than SBL.
