Abstract:

Starting from the conceptual characteristics of the correlation coupling of urban-rural system, taking 34 prefecture-level cities in the three provinces of Northeast China as research units, using the data of urban and rural development from 2003 to 2017, and using the grey correlation model, this paper studies the internal driving factors, spatial and temporal characteristics, and the regional types of urban-rural correlation coupling. The results show that: the correlation degree between urban and rural factors in the three provinces of Northeast China is over 0.5, which is a relatively high correlation. The strong factors for urban and rural system are concentrated on the economic and spatial fields of urban subsystem and the economic field of the rural system, and the strong factors of the urban sub-system are obviously more than that of the rural subsystem. In 2003-2017, the average urban-rural coupling degree in Northeast China showed a gradual decline, from 0.788 to 0.692, indicating that the urban-rural interaction tended to be eased and the coupling between urban and rural areas increased. The spatial pattern of urban-rural coupling in the three provinces of Northeast China showed “south low north high, north south difference narrowing, high value is concentrated in the backward areas of the three provinces and the four major centers is the polarization of low value”. The correlation coupling of urban and rural areas in 34 cities in the three provinces of Northeast China can be divided into five evolution types: high level coordination stability type, high level coordination regression type, lower level coordination decline type, low level and lower level coordination rising type, low level and lower level coordination stability type.

Key words: urban and rural system, correlation coupling, regional type, the three provinces of Northeast China
