Analysis on the Coupling Coordination Degree between Urban-Rural Construction Land and Economic Growth Rate in the Central Plains Urban Agglomeration

Abstract

This paper selects 30 cities in Central Plains urban agglomeration as spatial units. The coupling coordination degree and relative development degree between urban-rural construction land and economic growth rate in different development stages of cities in Central Plains urban agglomeration are calculated and analysed based on the area of urban-rural construction land and Annual Gross Regional Product (GDP) in each town in the past 20 years (2001-2020). The research shows that, in the past 20 years, the coupling coordination degree between urban-rural construction land and economic growth rate in the Central Plains urban agglomeration has generally developed toward a high value. In the high-level coupling stage, cities tend to change from northwest to Southeast in space. Secondly, from the perspective of relative development degree, the spatial differentiation of development characteristics of cities is apparent, and the changes of cities along and to the north of the Yellow River are the most significant. Almost all of them are characterised by economic growth lagging behind the growth of urban-rural construction land. We should pay attention to optimising the regional development model in time.
