Abstract:The development of the aviation equipment manufacturing industry has a profound impact on China's effectiveness in building an "aviation power" and "manufacturing power". By analyzing the structure and evolution of my country's aviation equipment manufacturing industry patent cooperation network, it will help improve the technological innovation capabilities of the aviation equipment manufacturing industry. Taking China's aviation equipment manufacturing industry as the research object, based on the application of the invention patent data in 1985—2018, the social network analysis method is used to construct the patent cooperation network of aviation equipment manufacturing industry and analyze Patent Cooperation Network Topology and Network Evolution Characteristics of Aviation Equipment Manufacturing Industry in China. The results show that China's aviation equipment manufacturing industry has achieved rapid development. Enterprises dominate the patent cooperation network, but the network is loose as a whole,the cooperation is not close enough,and the scale-free and small-world characteristics of the network are obvious. From the evolutionary law, the network scale continues to grow, but the density continues to decrease, and the network nodes change in stages.
