Abstract: Youth-oriented is a kind of accurate communication phenomenon targeting young audience that appears in the documentary field in China in recent years. On the whole, its exploration is carried out in all directions, covering the production layer, content layer and communication layer of documentary. But the development is not balanced, the production layer and the communication layer are getting mature, the content layer is relatively lagging behind. Especially the space of topic selection has the risk of narrowing, and the ideological value has the tendency of introversion and shallow generalization, since some documentaries do not have an in-depth and comprehensive understanding of the young audience, or an open mind to grasp the universality, and their creation is driven by the audience's superficial needs and technical skills. Based on this, this paper believes that the in-depth exploration of contemporary young people's social and cultural psychology in the public sphere of their concern and attention to the interpretation and understanding of the world creative ideas is conducive to the young documentary to complement the shortcomings.
