In other words, cybersecurity is essentially a subjective state。 No matter cybersecurity will bring about profound changes in the international political interaction, or network attack and defense are difficult to become an important tool for national strategy。 It only reflects the cognitive differences and their security practices of different main body of the cybersecurity。 It means that cybersecurity is largely plastic, and the over-interpretation of cybersecurity risks further strengthens threat awareness, leading to conflict-based and control-oriented security practices that actually create a lower trustworthiness and a weakening of rules of the cybersecurity environment。 Similarly, security can also be achieved through the cognitive construction process to "security", that means moving the issue down from the security and strategy of high political discourse structure and returning to the daily public discourse and ordinary political coordination areas。 Thus, discourse constructors tend to argue against cybersecurity issues and think that critical cybersecurity policies and practices should be critically rethought because it is these policies and practices that reinforce the principles of conflict and negative cognitive socialization。 As Kavidi says, "recognizing the political power and the preferences that behind the way in which threat statements are expressed will help people to understand the fact that cybersecurity does not necessarily have to compete with power, war and military action together, people always have other better policy options。 "

Discourse construction theory points out that in order to form an effective cooperation between the two objects, we must first reconcile the inherent differences in the practice of security。 Only when behavior subject’s idea of cognition of the source and nature of the threat become closer, the response and the special political rules can be coordinated with each other rather than contradictory。 Effective international cooperation is an important conceptual basis。 This view effectively not only explains the important reasons why it is difficult to promote international cooperation in cybersecurity, but also provides theoretical support for the factors such as the degree of development and cultural differences into the cooperative agenda。 Then I will make a comparison of the governments’ discourses of cybersecurity between America and China。
