[Abstract] A new round of information technology revolution represented by 5G will further promote human

beings to enter the “landscape society”of“image”survival. From the theoretical perspective of para-social

interaction， this paper explores the new forms of knowledge presentation in the live broadcast era and how

the publishing house realizes the new format of knowledge innovation through live broadcast. Based on the

analysis of theory and practice， this paper focuses on the development of direct marketing in the publishing

industry， and proposes a path worth exploring， including ： constructing a diversified product form under the

transformation and upgrading of the cultural industry，creating a new fusion of technology and talent content

productivity and communication，building a new type of publishing think tank that promotes the high-quality

development of the publishing industry.
