Priority digital publishing of academic journals, also known as On-line First, refers to publishing the contents of printed journals in advance through digital publishing methods such as the Internet and mobile phones.

The emergence of priority digital publishing mode is an objective requirement for the development of publishing industry and an effective way to solve the problem of publishing time lag. The publishing time lag has always been one of the problems that plague the development of the publishing industry. The long time lag not only leads to the loss of initiative, timeliness and cutting-edge of the author's scientific research achievements, but also affects the evaluation and reward of the author's professional title. It also makes it difficult for readers to obtain scientific research trends, research progress and latest technology applications in time, update their knowledge base in time, and even miss important first-hand information. For publishing units, too long publishing time lag will also make journals lose their attraction and core competitiveness to excellent manuscripts at home and abroad. With the support of the General Administration of Press and Publication, China Knowledge Network officially launched the priority digital publishing of academic journals in China on 20 10 and 10, which opened a new era of digital publishing of academic journals in China.
