Abstract: Empirical facts show that China has the abnormal phenomenon of low level of intellectual property protection with high level of export sophisticationFrom the perspective of the special “dual track” system of intellectual property protection，this paper provides a reasonable explanation for the above abnormal phenomenonBased on the data of judicial patent protection and administrative patent protection，this paper finds that only administrative patent protection can enhance enterprises' export sophistication，thus administrative protection has played an important role in enhancing enterprises' export sophistication under conditions of insufficient judicial protection of intellectual property rightsHowever，judicial patent protection and administrative protection can't be performed coordinatelyFrom the perspective of mechanism，intellectual property protection has increased enterprises' export sophistication mainly through independent innovationThe results of heterogeneity analysis show that the impact of judicial patent protection and administrative protection on enterprises' export sophistication is different across regions and industriesThis study effectively answers the question of the deviation between China's intellectual property protection and the export sophistication，which is helpful to deepen the understanding of the structural characteristics of China's intellectual property protection system and its trade effects，so as to provide some enlightenment for further promoting the reform of China's intellectual property system
