Abstract Under the situation of science and technology competition, the breakthrough of key common technology is of great significance to realize the self-reliance of high-level science and technology.This paper uses patent technology network analysis method, through constructing the inter-organizational cooperation network and technology network integrated analysis framework, selects two typical technologies named as “aircraft engine parts of hot end temperature protective coating”and “3D printing metal powder preparation and application”, to explore the evolution characteristics of key common technology networks.The results show the followings.①The core actors represented by leading enterprises, high-level research universities and top scientific research institutes cooperate with other innovation actors to integrate resources and tackle key common technologies;②Multiple actors such as universities, enterprises and research institutes form a complex multilateral network connect closely;③The key common technology network presents a “core-edge”structure, and related technologies are interrelated around the core technology nodes, forming multiple technology clusters;④With the continuous evolution of the network, the diffusion and spillover effects among the key common technologies are enhanced, which have a significant externality.The results provide implications for the distribution and management of key common technologies in China.
