The growth of urban agglomeration has periodical characteristics and regular pattern, and it develops unevenly in spatial structure at beginning stage, which manifests a core-periphery structure. Harbin-Changchun urban agglomeration is one of the key urban agglomerations that is listed in state-level urbanization planning, so it is of great significance to analyze its spatial structure and measure its growth stage for the practical works. From the perspective of the core-periphery theory, this article divides Harbin-Changchun urban agglomeration into the core area and the peripheral area, then the article uses fuzzy comprehension evaluation method to set up the evaluation index system and the evaluation index standard to evaluate the growth degree and stage of Harbin-Changchun urban agglomeration. Finally, the article discusses the strategic policies for constructing Harbin-Changchun urban agglomeration. The result of the research indicates that the growth of Harbin-Changchun urban agglomeration has the characteristic of 3-core-periphery spatial structure. The core area includes 22 districts and the peripheral area includes 83 districts and counties. Harbin-Changchun urban agglomeration is in the later stage of its embryonic growth stage and urban system is immature. The core area is mainly agglomeration while radiation effect is not strong. The industrial structure in the peripheral area is characterized by convergence, the inter-city accessibility and informatization level are low, the infrastructure is not developed enough, and the development of the export-oriented economy is not sufficient. Regional development in the urban agglomeration is uneven. It is necessary for the core area of Harbin-Changchun urban agglomeration to continue to strengthen Harbin and Changchun as regional central cities and enhance the construction of the central cities. It is also necessary for the peripheral area to be deeply involved in their core area’s economy, improve connectivity with central cities, strengthen regional cooperation, and promote coordinated regional development.

This paper develops a simple model that shows how a country can endogenously become differentiated into an industrialized "core" and an agricultural "periphery." In order to realize scale economies while minimizing transport costs, manufacturing firms tend to locate in the region with larger demand, but the location of demand itself depends on the distribution of manufacturing. Emergence of a core-periphery pattern depends on transportation costs, economies of scale, and the share of manufacturing in national income.
The Structures Systems of Urban Agglomerations (SSUAs) in China are the spatial and synthetic polymers coupled organically by Urban Agglomerations with different development degrees, grades, political relationship, formative reasons and spatial locations through various flows of substance, power, information and knowledge. Based on the synthetic analysis of the SSUAs at home and abroad, it is found out that world SSUAs are in the process of formation, the functions with different grades for Urban Agglomerations are fabricating profoundly now through new international division of labor and region, and at the same time, although Urban Agglomerations are in the incipient phase as a whole, they are the most vigorous strategic strong point and growth pole with the greatest potential in the economic development framework in the future, and they will dominate the economic development orientation in China. The paper identifies three grades according to the calculating results using of model subject to the index of development degree for Urban Agglomerations in China. The first grade group constitutes Urban Agglomerations on the Yangtze River Delta, Pearl River Delta and of capital Metropolitan Coordinating Region. The second grade consists of 11 Urban Agglomerations in Shandong Peninsula, Chengdu and Wuhan metropolitan coordinating regions. The third grade group is composed of 14 Urban Agglomerations in the central Yunnan Province and the north Tianshan Mountains. Further analyses indicate that there are great differences among the 28 Urban Agglomerations, but such differences are reasonable to some degree. They have showed some characteristics of regional heterogeneities including different development phases, non-equilibrium in overall distribution, regularities in regional heterogeneous pattern, distinct disintegration and heterogeneity in inter-conglomeration. Based on the above analyses, the paper suggests that future studies should focus on the theoretical studies of the multi-dimension, regularity and phase subject of the SSUAs in China, enhance studies on the differences in heterogeneity and competitiveness in the formation and development of the SSUAs and reinforce research on their internationalization, globalization and dynamic monitoring.
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 groupsn 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 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.

This article summarizes the characteristics of urbanization development and the changes of industrial structure in Northeast China, analyzes the relation of urbanization and the changes of industrial structure in Northeast China by applying the mutually prompt law of urbanization and industrialize, the law of the changes of industrial structure and the law of urbanization development, and discusses the reasons of forming this relation. Finally, this article puts forward harmonious strategy on the relation of urbanization and the changes of industrial structure in Northeast China. that is, promoting harmonious development of urbanization and industrial structure by optimining industrial structure, building the reasonable urban system and improving the level of infroastructure.
