This article analyses whether and how Taiwan's exports are sensitive to national differences in intellectual property right (IPR) protection, as well as the degree of imitation threat. Applying a longitudinal IPR index developed by the World Economic Forum (WEF) and using the generalized method of moments dynamic panel data modelling technique to control for endogeneity and panel unit root problems, the empirical results show that the strength of importing countries' IPR protection has a positive impact on Taiwan's exports, supporting the standpoint of market expansion that stronger IPR protection will induce more trade. Under various classification systems to differentiate the degree of threat of imitation across countries, both positive and negative export effects of IPR are found in Taiwan's case. However, the pattern of threat of imitation-trade nexus seems to contradict theory predictions. Moreover, high-tech exports are found be more IPR sensitive than non-high-tech exports.
