| Summary: | 本研究以台灣48家上市上櫃電子業公司為樣本，以其實際經營資料探討以下兩項問題：
一、取得品質認證後之經營績效是否優於取得品質認證前？
二、研發投資是否與其經營績效呈正相關？
研究結果如下：
一、取得品質認證與經營績效之關係
1.我國電子業上市上櫃公司取得ISO 9000系列品質認證後年度之銷售收入成長率較取得認證前為佳，即對公司而言，取得品質認證有助其銷售收入之成長。
2.我國電子業上市上櫃公司取得ISO 9000系列品質認證後年度之修正權益報酬率、營業利益成長率、淨利成長率與取得認證前無顯著差異，即表示取得品質認證與否對公司之修正權益報酬率、營業利益成長率、及淨利成長率沒有影響。
二、研發投資與經營績效之關係
1.我國電子業上市上櫃公司之研究發展強度與其修正權益報酬率存在正向關係，且其關聯持續三年。但研究發展強度與修正權益報酬率間存在一年的時間落差，即當年度的研發投資，其效益在次年度才顯現出來。亦即當年度研發強度較大的企業，其次年、後年及第三年的修正權益報酬率較好。
2.我國電子業上市上櫃公司之研究發展強度與其銷售收入成長率呈正相關，且其關聯持續三年，即研究發展強度大的企業，其當年、次年及後年的銷售收入成長率比較好。
3.我國電子業之上市上櫃公司研究發展強度與營業利益成長率、淨利成長率未呈顯著相關。
=== This study empirically examines both the relationship between ISO 9000 certification and operating performance and the relationship between research and development (R&D) investments and operating performance of 48 electronics engineering (EE) companies.
The empirical results show that：
1 .The relationship between ISO 9000 certification and operating performance
(1) After the EE companies passed the ISO 9000 certification, the ratio of sales growth is higher, compared to that before passing the certification.
(2) Whether the EE companies passed the ISO 9000 certification has no effect on either their modified return on equity or ratio of operating income growth or ratio of net income growth.
2. The relationship between R&D investment and operation performance
(1) R&D intensity of EE companies was significantly and positively associ: ated with the modified return on equity. Moreover, the significant and positive association was found for three years.
(2) R&D intensity of EE companies was significantly and positively associ: ated with the ratio of sales growth. Moreover, the significant and positive association was found for three years.
(3) R&D intensity of EE companies was not significantly relative to either ratio of operating income growth or the ratio of net income growth.
