Abstract: This paper gives a definition of network technology alienation and expounds its subjective source. Trapped by network technology activities， people have lost their control over network technology and their essential attribute of being human beings. The design and application of network technology is merely directed towards efficiency and utility， and as a result， human beings， as a defective existence， have gradually lost their subjective status， which is the very subjective source of network technology alienation. In order to reconstruct their subjective status and eliminate network-technology alienation， human beings should transform from subjectivity to intersubjectivity， follow the relevant network ethics and make it their own code of conduct.

Key words: network technology, alienation, subjectivity, intersubjectivity
