根据城市群、城市组群及城市群组的内涵指出中国东北地区目前存在辽中南、吉林中部、哈大齐三个城市群组。按照其形成发展过程和现状特征,辽中南已经发育成为成熟的城市群,而吉林中部和哈大齐尚处于城市群发育的中间阶段,即城市组群阶段,从而在东北地区形成了"一群二组"的空间结构框架。通过对东北地区城市群组外向功能量和城市流强度的计算发现,群组内部尚未出现主要外向服务部门区位熵均大于1的城市,与国内发达城市群的发展水平相距较远。未来发展应该围绕城市群组的组织结构、网络化发展模式、职能分工与功能互补、发展关系协调等方面进一步调控和优化。

The urban agglomerations in Northeast China group grew up in the special historical period, under a special economic background, and its unique structure and function has been the regional labor division of the old industrial bases in Northeast China, even controled the economy development in Northeast China. According to the connotation of urban agglomeration, cities group and urban agglomeration group, this paper pointed out there currently exist objectively three large urban agglomerations, namely, urban agglomerations of Central Southern Liaoning, Central Jilin and Harbin-Daqing-Qiqihar in Northeast China. According to the formation, development process and the present situation, Central Southern Liaoning has already developed into a mature urban agglomeration, while Central Jilin and Harbin-Daqing-Qiqihar are still in intermediate stage of urban group development. Thus it has been formed a spatial structure with'an agglomeration and two groups’in Northeast China. By the analysis on the urban extroversion meritorious energy and urban flows intensity in three large urban agglomerations in Northeast China, it was found that there is not any city’s location quotient for the main extrovert service of the urban agglomeration being greater than 1. And their development levels were lower than that of domestic advanced urban agglomeration. The future development should focus on urban agglomeration organization structure, network development pattern, function division and complementary, development relationship coordination, etc., and further control and optimization are needed. Central Southern Liaoning should strengthen the benefit mechanism and efficiency mechanism when the heavy industry and equipment manufacturing continuously develop; Central Jilin should consolidate industrial relation, sticking to the development of automobile industry and emerging industries; Harbin-Daqing-Qiqihar should lay emphasis on resources-substitute industry and emerging industries.
