摘要

本研究旨在探討中華職業棒球大聯盟(簡稱中華職棒)運動員的運動表現與其薪資的關聯性，以自2008年至2016年球員之運動表現及薪資為研究對象，將各項運動表現數據，與球員之月薪進行關聯性探討。研究之實證研究結果如下：一、在投手的運動表現方面以國籍與薪資有高度負相關，而奪三振、先發、勝場、投球局數、面對打席、無四死球、投球數、被安打等與薪資有較高的正相關。投手的國籍為外籍、無四死球場次多、救援成功場次多、先發場次多、四死球場次少、救援失敗多，且勝率高，可以獲得較高的薪資。在野手的運動表現方面以銀棒指數、全壘打、打點、四死球、壘打數、攻擊指數、得分、故意四壞球、二壘安打、安打、長打率等與薪資有較高的正相關；野手的銀棒指數高、出賽數少、四壞球多、外籍球員、犧牲飛球多、三壘安打數少、長打率高、打數越多者，可以獲得較高的薪資。另外在不考慮野手的銀棒指數狀況下，野手的出賽數少、四壞球多、外籍球員、犧牲飛球多、三壘安打數少、長打率高、打數越多、故意四壞球多、打席越少、守備位置少、投球習慣為左手、二壘安打數少、打擊率低、三振數少者，可以獲得較高的薪資。本研究所得預測棒球選手薪資公式可作為各球團核薪的參考指標，並提供球員與球團洽談合理薪資的重要參考依據。

並列摘要

This research is aimed to explore the relevance between on-field athletic performance and salary of the players at the Chinese Professional Baseball League (hereafter referred as CPBL). The study takes the statistics and salary information from players during CPBL seasons between 2008 and 2016 to explore its relevance.
The empirical research results are as followed:
For pitchers, there is significant negative correlation between salary and nationality, and there are higher positive correlations between the salary and number of strikeouts, games started, games won, innings pitched, games with no base on balls, pitches and hits allowed.
Pitchers with foreign nationality, more games with no base on balls, more saves, more games started, less games with base on balls, more blown saves and high winning percentages are to be awarded with higher salary.
For the fielders, there are higher positive correlations between salary and silver-slugger index, number of home runs, RBIs, bases on balls, total bases, runs, OPS (on-base percentage plus slugging percentage), intentional walks, doubles, hits and slugging percentages.
Fielders with higher silver-slugger index, fewer games played, more base-on-balls, foreign nationalities, more sacrifice flies, fewer triples, higher slugging percentages, more at-bats are to be rewarded with higher salary. With the exclusion of silver-slugger index, fielders with few games played, more base-on-balls, foreign nationalities, more sacrifice flies, fewer triples, higher slugging percentages, more at-bats, more international walks, fewer plate appearances, fewer defensive positions, throws left, fewer doubles, lower batting averages and fewer strikeouts are to be rewarded with higher salary.
The salary prediction formula developed based on this research can be applied by the clubs as reference measures to approve payroll. It can also be provided to the players as important and essential reference to negotiate for reasonable salary.
