From the perspective of population, land, economy, society and ecology, the index system of new-type urbanization in the three northeastern provinces is constructed to measure the development level of population, land,economy, society, ecology and comprehensive urbanization in the three northeastern provinces and their 34 prefecture-level cities, and divide their coordinated development stages. The comprehensive urbanization development level of Liaoning is higher than that of Jilin Province, while that of Heilongjiang province is lower. Liaoning province has the greatest potential for economic urbanization development, Jilin Province has advanced land urbanization development, and Heilongjiang Province has positive and good ecological urbanization. The high-value zones of the circle urbanization are prominent, and the low-value zones are distributed in the coal-electric-chemical base in the eastern part of Heilongjiang Province. The urbanization of Liaoning and Jilin is in a mild imbalance and recession on the whole, while Heilongjiang is in a moderate imbalance and recession, with Shenyang and Dalian as the primary coordination and Harbin and Changchun as the reluctant coordination, showing a spatial trend of the expansion from the four core high-value areas of Harbin, Changchun, Shenyang and Dalian to low-value areas.
