The 20th National Congress of the Communist Party of China proposed to carry forward the spiritual pedigree of the Chinese Communists with the great spirit of party building as the source. Red archives are an important carrier of the spiritual pedigree of the Chinese Communists, and play a unique role in inheriting the red genes. This paper summarizes the connotation and characteristics of red archive resources and the theoretical value of mining red archive resources for Party school teaching, and strengthens the cultural consciousness and historical self-confidence in developing and utilizing red archives resources. At present, red archive resources are widely used in the teaching of Party schools, but there are still insufficient development and utilization. It is urgent to carry out systematic planning, overall deployment and overall promotion, establish a cooperation mechanism between Party schools and local archives and culture departments, establish a mechanism of innovating Party school teaching methods by using red archive resources and establish a cross-regional cooperation mechanism of red archives resources in the Party school system to create a high-quality and efficient practical path for the development and utilization of red archives resources.
