本研究主要探討影響全球資訊服務與專利及商標服務業貿易的關鍵因素。主要挑選全球42個國家。研究年份為2006年至2012年，以擴充空間引力模型(Augmented Spatial Gravity Model)為實證模型，並採用Breusch-Pagan LM檢定、Hausman檢定以及Hausman-Taylor檢定，選取最合適的實證方法。實證結果發現，資訊服務存在明顯的母國市場效果(home market effect)及地主國市場效果(host country effect)，且進口國視資訊服務為奢侈品，而專利及商標服務僅受到地主國市場效果的影響。其次資訊服務與專利及商標服務屬於研發密集型服務業(R&D-intensive services)，因此R&D的投資與ICT環境的建置的都有正向的影響。再者，本研究發現市場潛力產生的負向關係，代表資訊服務的貿易方式有別於過去貨貿的平台出口方式，進而偏好直接出口至目標國家，而在2008年的金融海嘯正向的帶動全球對於資訊服務的需求。

This study mainly investigates the determinants of services trade in computer and information services and royalties and license fees from 42 countries, during the period from 2006 to 2012. The study utilizes the augmented spatial gravity model and employs the Breusch-Pagan LM test, the Hausman test and the Over-identification test of the Hausamn-Taylor to choose the appropriate empirical method. The empirical result reveals several key findings as follows. First, the obvious home market effect and host market effect exist in computer and information services and importing country regards the computer and information services as luxury goods. Second, computer and information services and royalties and license fees are regarded as R&D-intensive services, so that the ICT infrastructure, including Internet use and e-readiness, as well as R&D expenditure, clearly strengthens exports of both services. Third, according to the negative impact of market potential, computer and information services prefer direct exports to the destination due to their virtual and invisible characteristics. Finally, financial crisis increases the demand for the computer and information services.
