The main structure of digital personnel is "one foundation and four pillars". "One foundation" refers to the professional foundation, mainly the education, examination and initial training of quantitative tax cadres. The "four pillars" include usual assessment (daily performance), accreditation assessment, professional ability assessment and leadership ability assessment. Quantitatively record all kinds of data and information to form a comprehensive evaluation score, which is included in the personal growth account, providing a comprehensive, objective and accurate data reference for organizational application and personal growth, and is linked to cadre appointment and annual assessment.

With the advent of the era of big data, the integration of big data with all walks of life is getting closer and closer, and tax authorities also use emerging technologies to accelerate the modernization of personnel management of tax cadres, and "digital personnel" came into being.

Digital personnel means that the tax department uses the digital personnel information system to comprehensively record and quantify the professional foundation, professional ability, leadership ability, daily performance, recognized evaluation and other data information of tax cadres, and then form a comprehensive score and count it into the personal growth account, providing comprehensive, objective and accurate data reference for organizational application and personal growth.
