Abstract: The three driving forces behind the high-quality development of the publishing industry， supply side reform， and digital empowerment constitute the underlying logic of contemporary book editors’ transformation and development in content production， supplydemand matching， and publishing innovation. In terms of content production， the publishing industry calls for high-quality books with cultural connotations and profound value; in terms of supply-demand matching， supply side reform requires continuously activating the interaction between supply and demand， and accurately focusing on market demand; in terms of publishing innovation， the iteration of technologies such as 5G， Blockchain， and AI has provided rich inspiration and technical support for publishing innovation， greatly unleashing the industry’ s value-added potential. Based on these underlying logic， the role positioning of contemporary book editors should be mainly cultural defenders， market analysts， and publishing innovators， and it is necessary to achieve transformation and development through three action paths ： professional， market， and technical ： building a solid professional foundation and ensuring high-quality book content ； strengthen market awareness and explore effective ways to connect supply and demand; upgrade technological level and achieve diversified innovation in publishing methods.
