摘要 Abstract of the paper	We construct a duopolistic trade model and apply royalty licensing in the model to study the effect of a tariff policy on social welfare and international technology transfer. Besides, we also compare the optimal tariff rate and social welfare under different licensing types. We show, under royalty licensing, technology transfer always occurs, and consumer surplus decreases with the tariff rate. Moreover, it is found that the optimal tariff rate under royalty (fixed-fee) licensing is the highest (lowest), social welfare under fixed-fee (royalty) licensing is the highest (lowest), and two-part tariff licensing is in-between. Furthermore, we also consider a model with one private firm competing with a partially privatized public firm in a domestic market under fixed-fee licensing and find that the technology-transfer-inducing tariff rate decreases as the degree of privatization decreases. Additionally, the optimal tariff rate is prohibitive when the degree of privatization is significantly low.
