Abstract:Intellectual property trade is closely related to the division of labor and the distribution of benefits within global value chains, thus has become an important tool for countries seeking international competitive advantage. To study the evolution of the international intellectual property trade pattern and its influencing factors and mechanisms, and to clarify China’s position within it, this research selects intellectual property royalty data from 66 major countries and regions. It constructs an international intellectual property trade network from 1995 to 2018, using social network analysis methods to depict the network’s topological structure, spatial layout, and node characteristics. Additionally, based on the innovation-cultural distance-administrative distance-geographic distance-economic distance framework, an exponential random graph model is employed to explore the mechanisms of network formation and evolution. The results show that: the international intellectual property trade network exhibits small-world characteristics and a clear “core-periphery” structure; the centralization trend gradually strengthens but later weakened in times of turmoil. The core position of developed countries, particularly the United States, continued to decline. By 2018, the core countries were Germany, the Netherlands, Switzerland, the United Kingdom, and the United States, in a balanced situation. China has maintained strong growth momentum, with the average annual growth rates of both exports and imports surpassing the growth rate of the total international intellectual property trade. Additionally, the total value of intellectual property trade in 2018 increased nearly 47 times compared to 1995. However, its trade deficit has been continuously expanding. The intellectual property trade network shows a cyclical closure effect, but there is no strong interdependence between countries. Innovative level, administrative level, economic level, cultural distance, and geographical distance all influence the formation of intellectual property trade relationships to some extent.
