Abstract: Space is not only the field of technology, but also the functional boundary of technology. The technical logic of national governance practice is reflected in the complex ecology of the interaction pattern of administration and politics and society, technology and value and form. There is a structural deviation in public management’s cognition of technological space. Technological narrative cannot be confined to the perspective of management tools, nor can it go beyond the development limit and objective conditions of time and space. The external technological scene of national governance is not only the management efficiency, but also the ability to integrate the state and society into the community to use tools and allocate resources. The internal technical scene of national governance is not only the management project, but also the allocation of administrative resources as a management practice. As a political practice technology is the way to realize value. As an institutional practice, technology is the foundation and practical way of form construction. Public management needs to objectively and comprehensively understand the technical space, treat the development of technology empirically, understand the essence of technology from administrative production, and reconstruct the technical scene of national governance with social engineering instead of management engineering.
