Analysis of the Structure of Technology Spillover on Industries by Analyzing Patents
نویسندگان
چکیده
The objective of this paper is to examine the structure of technology spillover from UAV (Unmanned Air Vehicle) technology on other industries by analyzing patents. The network analysis of the USPTO (United Stated Patents and Trademark Office) patent data from 1981 to 2000 was adopted to investigate the characteristic change of the technology spillover. The results show that the influence of UAV technology on other industries has grown over the twenty-year period. For weapons system development, this study provides a research basis to estimate the technology spillover effects on industries. Searching a structural hole from the inter-industrial knowledge flow structure may be a useful technique to find core technologies which generate large technology spillover on the other industries.

متن کاملThe Effect of Technology Spillover from FDI: An Empirical analysis of Chinese Manufacturing Industries
This paper examines the effects of technology spillover from FDI based on panel data analysis of Chinese large-scale domestic manufacturing industries. We use the panel data of 27 Chinese manufacturing industries from 2001 to 2007. We estimate technology spillover effects by two steps. First, we estimate the total factor productivity of domestic firms’ and foreign firms’ by Cobb-Douglas Product...
