This paper classifies air cargo logistics providers allowing analysis of high-technology manufacturers’ choices of providers. Data are collected from high-technology manufacturers in Taiwan’s science parks. Forwarder providers are put into three categories and nested logit model are applied to explore what service performance factors influence high-technology manufacturers when selecting third party logistics providers. Delivery is found to be the most important factor. It is found, for example, that two express providers with high levels of customer satisfaction and market share could compete more effectively by exercising differential strategies.
