1. The concept is different: a subject leader refers to an expert who has a very high academic level in an academic field in a university and can lead, guide and organize relevant personnel to carry out academic research in that academic field and obtain research results. In a certain range of teachers, backbone teachers have relatively excellent professional ethics and quality, have a certain popularity, are recognized by everyone, and have rich educational experience.

2. Different in nature: the academic leader is a kind of honorific title, not a title or position, and there is no uniform standard. The backbone teachers represent a part of the teachers' group and have certain popularity and influence.
