DOI is the abbreviation of digital object identifier, which is translated into digital object identifier and is usually used to identify digital files and document information. In fact, doi papers use digital object identifiers to identify research papers tracked and cited around the world. These digital object identifiers can be connected to the database on the network to help readers and researchers find the required literature information quickly and accurately.

In the field of academic publishing, DOI has played an extremely important role. When a research document is given a DOI identifier, it can be considered as an officially published article. This not only improves the credibility and authority of academic research, but also simplifies the process of literature citation. Researchers can ensure that they quote other authors' research results correctly by pasting DOI into their literature citations.

Generally speaking, doi papers have become an important academic citation standard, which brings a lot of convenience to academic research. Through digital object identifiers, readers and researchers can easily access the research literature they need. The use of DOI has also promoted the development of academic journals, accelerated the dissemination of academic achievements, and promoted the process of academic exchanges, which is of certain significance to academic progress.
