The Evolution of Distribution of Technology Transfer in China: Evidence from Patent Licensing

Abstract

This study explores the temporal and spatial distribution of technology transfer in China by analyzing the licensing activities from the perspective of supplier and demander of the technology transfer chain, using the data obtained from the State Intellectual Property Office of China (SIPO). We find that the overall number of licensed technologies has increased dramatically during 10 years and different types of technology show diverse trends. And the technology age is declining year by year, among which the age of invention patents is the oldest. As licensors, individuals and firms provide the vast majority of outward technologies and most of their technologies are utility models. However, only firms take the vast majority as licensee. And most inward technologies come from foreign organizations before 2008, while domestic sources provide the majority of inward technologies after 2008. We also provide suggestions for policy-makers and firms.
