面對競爭日益激烈的全球化社會，全面品質管理顯得更趨重要，我國為提升產業競爭力與整體品質水準，設立國家品質獎，以獎勵成功推行全面品質管理的公司。本研究針對得獎公司做分析，探討得獎價值(得獎發布日前後，公司股價之波動)，與公司獲獎後的長期表現。
在得獎價值方面，採用二次指數平滑法(Double Exponential Smoothing)與彈性倒傳遞類神經網路(Resilient Backpropagation )，發現部分公司發布日前後之股價，受獲獎訊息影響，但受影響之公司占整體獲獎公司之比例不高，整體得獎價值不顯著。在長期表現方面，以三種角度(年度、類股、個股)分別比較，公司之長期股價報酬率，與所屬類股之股價報酬率，何者較佳，最後發現兩者無顯著的差異。

Total quality management (TQM) is a key to success in competitive world. To encourage the companies to fully conduct TQM in production process, Taiwan government set up National Quality Award (NQA). This study investigates the short term impact of award-winning news on the market price by using exponential smoothing and resilient backpropagation. This study also extends to the long-term observation by comparing the return on investment (ROI) between award-winning companies and market sector indices.
It concludes that the stock price of the award-winning company may be upward in short-term, but no significant stock fluctuation in large parts of them. Furthermore, there is no evidence showing that there is significant contribution to the stock price comparing with the market sector indices in the long run.
