Abstract: Network political screen capture is mainly aimed at the screen capture behavior of political subjects on political topics, politicians, political discourse, political decisions and other political contents on the network platform. Political screen capture can be divided into active and passive screen capture. Active screen capture behavior reflects positive political psychology, including political participation, political identity, political communication and political trust psychology. The negative political psychology lies in the passive screen capture behavior, including political apathy, political distrust, political obedience and political compromise psychology. The positive political psychology of political screen shots has positive political function, while the negative political psychology of political screen shots has negative political function. To this, on the network platform, we should not only reflect the initiative, actively participate in network political screen shots to stimulate people's enthusiasm and interest in participating in politics, but also be alert to the negative political psychology brought by passive political screen shots to prevent threats to the security and stability of network political space, so as to create a political space suitable for network political screen shots.
