本研究以民國90和95年度工商普查資料，探討資訊科技的使用對於製造業廠商生產力的影響。生產力採用勞動生產力方式和Aw et al.(2003)多邊指標法(multilateral index)的總要素生產力兩種衡量方式。資訊科技則考慮了使用電腦設備、系統協助作業和電子商務行為等變數。實證模型中也控制了廠齡、廠商規模、資本密集度、平均員工薪資、研發密集度和產業別特性等因素。實證結果歸納如下：(1)、資訊科技利用，無論是使用電腦設備或是系統協助作業又或者採用電子商務行為，對製造業廠商的生產力是有顯著正面影響。(2)、高科技產業的廠商使用資訊科技並沒有比傳統產業在生產力上擁有明顯的優勢。The purpose of this study investigate the impact of information technology on the productivity of manufacturing. Based on the 2001 and 2006 Taiwanese Industry and Commerce Censuses. Productivity is measured by labor productivity and total factor productivity proposed by Aw et al.(2003). The variables of information technology include the use of computer equipment, software systems, and E-commerce. The controlled variables in regressions contain plant age, firm size, capital intensity, average wage, R&D intensity, and industry characteristics. There are two main conclusions: first , productivity is strongly positively associated with the use of computer equipment, software systems and E-commerce . second , there is little evidence that the productivity gain of using information technology is meant significant in technology-intensive industries than in traditional industries.
