This paper aims to interpret the contradiction of good livability of counties of Northeast China and "new phenomenon of Northeast China" from three aspects such as livability compositions, resident attributes and resident groups. Studies reveal that environment health, county characteristics, traffic convenience, and municipal facilities of counties in Northeast China are good. The residents are not in pursuing the higher level of living, and are attaching importance to housing security. But there still exists some problems that the urban migrant worker groups and the early retirement groups are not satisfied with housing security and social security. Then from the aspect of county livability, this paper proposes revitalization strategies which include perfecting housing security, improving county characteristics, introducing high-income industries, providing decent work, constructing secure county, encouraging working outside and so on.
