In 2022-2023，the post-epidemic era has started，with European countries basically abolishing border epidemic control，and international population movement becoming normal. In Europe，the annual scale of international migration has increased significantly，and the diversity of international migration population has also increased significantly. The number of asylum applications has increased，and the approval rate has increased significantly. The proportion of immigrants in the total population continues to increase，and the proportion of naturalized immigrants is increasing accordingly. However，in terms of the flow and management of refugees and migrants，Europe still faces problems such as the implementation of integration policies and the response to sudden war refugees，and still faces two basic contradictions：on the one hand，most member states lack skilled labor and high-end talents，and hope to expand the opening to introduce immigrants；on the other hand，they are unwilling to bear a large number of “unskilled” or “low-skilled” war refugees，and bear a large number of additional social responsibilities. The second is the inherent contradiction that has always existed，that is，the contradiction between the principle of the supremacy of humanism and the principle of the supremacy of national interests of member states. Therefore，the governance of immigrants and refugees in Europe must strengthen the governance direction of integration construction. It is necessary to restore the economy as soon as possible，overcome the “migration crisis”，and strengthen the economic basis for the integration of refugees and migrants. In the end，peaceful development is the fundamental solution to the plight of war refugees in Europe.
