To investigate the pushing mechanism of information on cyber communication, the author constructed a model of pushing behavior based on literature view. In the algorithm experiment, it was observed that although information pushing had a clear and remarkable impact on the receivers, the probability of misjudgment of receiver behavior should not be ignored, and there were also technical loopholes in the balance between picky information receivers and other users. In addition, algorithm neutrality, the dominance of algorithm over network users, the contribution of the algorithm to collective attention and the relationship between the algorithm and the communication environment need further consideration. It is concluded that although information pushing is an upgrade of information acquisition, it still needs more practical test and feedback.
