Abstract: From the perspective of the inherent relationship between nation, nationalism, and techno-nationalism, techno-nationalism is the infiltration and manifestation of nationalist trends in technological activities. Its essential feature is that specific nation-state, in pursuit of maintaining their technological independence or leading position, require their technological activities to follow the principle of putting national interests first, emphasizing the distinction between "self-technology" and "other-technology". Techno-nationalism includes three aspects of emotions, theory and policy. Taking purpose-means as a parameter, the contemporary western techno-nationalism can be divided into four basic types: monopolistic-radical techno-nationalism, monopolistic-moderate techno-nationalism, self-interest-radical techno-nationalism, and self-interest-moderate techno-nationalism, which derive from different theoretical, practical, and institutional foundations.
