With the widespread application of digital media, artificial intelligence and other technologies, modern state governance and social participation practices are increasingly showing distinct characteristics of mediatization and technicalization. And as a participatory communication that coordinates the relationship between the state and society, it may not pay due attention to the mediating and regulating role of technological factors between the state and society. It also does not fully realize that the technological system is becoming an important element of national governance and participation in subject status. Therefore, in order to find a feasible path to open up the theoretical perspective of participatory communication, it is necessary for us to conduct a comprehensive and systematic investigation and inspection of the phenomenon of technological participation in state governance from the following three dimensions: Firstly, based on the perspective of 'post-humanism' , try to jump out of the 'people' as a single, absolutely centered thinking mode, reflect on the 'social-state' dual relationship as the core of the existing model of participatory communication, and lay the ideological foundation for incorporating the elements of technical participation; Secondly, starting from the concept of from people-machine relationship and human-machine symbiosis, consider the possibility of constructing a 'actor network system' of state governance, composed of multiple subjects such as individuals, society, technology, and the state, and enhance the theoretical status of technical participation factors; Moreover, compare the similarities and differences between the two different modes, and explore the significance of including technology as a participating subject in the theoretical framework of participatory communication for subject relationship reform, participation effect analysis, and theoretical and practical innovation.
