Abstract:

China attaches great importance to the strategic deployment of revitalizing the old industrial bases in Northeast China. Especially after the emergence of the "New Northeast Phenomenon", the future development trend of Northeast China became the focus of attention at home and abroad again. This paper, selecting Liaoning province, which is featured by obvious change of population and economic development, as the research object, establishes the index system and coupling coordination model of population and economy system, and explores the spatial evolution and differences of population and economy coupling coordination in Liaoning province since the "Revitalization of Northeast China". The results show that, during 2000-2015, the coupling relationship between population and economy in Liaoning province was gradually strengthened, showing a high level development trend. However, there were obvious fluctuations in the coordination relationship. The number of moderately incoordinated counties had been increasing, and the primary coordination areas had declined, and the main incoordinated coupling areas were the inland border areas of Liaoning province. The counties and cities with enhanced coupling degree and reduced coordination degree shared common characteristics. Population and economic changes were not synchronized, and the population composite index had been declining, while the economic composite index increased or decreased, which is also the main cause for regional imcoordination. In Liaoning province, where population and economy are both coupled and coordinated, there still exists a certain spatial structure of "circle + axis", in which circle refers to the three-circle structure (decreasing from center to surroundings) of Shenyang, Anshan and Dalian, and the farther away from the central area, the lower the level of coupling and coordination; the axis structure is the urban corridor of Shenyang-Dalian on the Harbin-Dalian High-speed Railway line, which forms a more obvious "gradient axis".

Key words: spatio-temporal differences, pattern evolution, coupling coordination, New Northeast Phenomenon
