Since the outbreak of COVID-19 pandemic，the speed of digitalization has been greatly accelerated，and the rapid development and application of artificial intelligence has created good conditions for organizations to carry out the transformation of digital intelligence in an all-round way. In today’s world，the organization and application of digitalization is not only to improve the speed，but to go further to make the full realization of the intelligence in an all-round way. Therefore，digitalization in the future must be digital intelligence combined with intelligence. For human resource management，if it wants to gain a place in the future，it is necessary to carry out comprehensive and profound changes in mathematics and intelligence. Specifically，the embodiment of digital intelligence in the field of human resource management is mainly：whether it has automated technology and means，and on this basis，through the improvement of data analysis capabilities，to achieve intelligent scene processing capabilities. Therefore，on the basis of the first three investigations，we continue to track and study the application of human resources big data and analysis，This paper investigates the current situation，problems and constraints of human resources automation scenarios，human resources big data and analysis application in different types of organizations，and puts forward the future development direction，so as to provide reference for improving the analysis ability of human resources data and promoting the transformation of digital intelligence.
