Abstract：In the past， ontology only focused on the ways in which synchronic things exsisted when it came to the question of existence. With the development in personal identity studies， and the scientific achievements of relativity have penetrated into the study of space-time and existential philosophy， the new research field of persistence， which has both the nature of pure ontology and the philosophical interest of personal identity， has emerged. The new tendency is to explain the personal identity across time in terms of persistence. Due to the different understandings of persistence，such as endurence， perdurence， and exdurence， different theories such as three-dimensionalism， four-dimensionalism and exdurenism have been born and developed in competition with each other. The related research not only expands and deepens the field of personal identity philosophy， but also shows us a field different from the traditional ontology—the diachronic space-time and persistence of its subject. In order to take a step further， we should do a lot of methodological exploration in addition to further research on ontology， epistemology， logic and philosophy of personal identity.
