由於我國工商業進步，家庭結構改變，雙薪家庭逐年增多，許多父母無暇為子女準備午餐。為配合社會發展需要，維護與促進學生健康，避免校園食物中毒事件發生，加速推動學校營養午餐，解決學生午餐問題，已為政府所重視，且為世界各國學校午餐之趨勢，然而文獻中顯少針對地區性業者做更進ㄧ步之研究，因此本研究擬探討團膳食材供應廠商之競爭力、競爭策略及產業環境，並以團膳食材供應廠商的角度來探討整體市場面之發展情況及前景，其中並以台南縣市中小學營養午餐為採購對象進行相關分析。
本研究針對團膳食材供應商作為研究對象，並將本研究之問卷設計為「背景資料」、「競爭策略」、「競爭優勢」、「經營績效」等4部分，試圖瞭解團膳食材供應商之各項指標，是否能夠真正符合顧客需求。
其中對相關公司主管部共發出問卷180份，回收150份，整體回收率為 83.33 ％ ，所使用的方法為t檢定分析、ANOVA分析、相關分析與迴歸分析。得到以下之研究結果：
(1) 公司員工多寡以及年齡對於競爭策略具有顯著差異
(2) 公司成立年數以及年齡對於競爭優勢具有顯著差異
(3) 公司成立年數、員工人數以及年齡對於經營績效具有顯著差異
(4) 競爭策略、競爭優勢以及經營績效彼此間無顯著相關
(5) 集中化策略預測對「競爭優勢｣會降低
(6) 集中化策略預測對「經營績效｣會增加
