Abstract: The risk aversion of network technology, the ideology of cyberspace, and the maintenance of cyberspace security all reflect the urgent need to strengthen the construction of network ethics. Examining the actual state of network moral construction, there are such practical problems as the dilemma of technology alienation obscuring individual moral consciousness, the lack of subjective rationality leading to moral anomie behavior, and the crisis of public characteristics disintegrating moral individual trust. To reconstruct the path of network moral construction, we must take the mainstream value as the guidance and fully implement the concept of "technology for good"; Guided by the mainstream morality, we should further promote the education of subjective rationality; Safeguard the network public order by means of the rule of law.
