Abstract
The coordination relationship between land urbanization and population urbanization is crucial for achieving sustainable development under economic transition. Moreover, the balance between land urbanization and population urbanization is essential to guarantee the urbanization process of an entire city. This paper empirically analyzes the interaction between land urbanization and population urbanization in Nanchang from 2002 to 2017 based on the coupling coordination model (CCM). The impacts of the coordination degree on coordinated development are quantified by multivariate linear regression (MLR). The results show the following: (1) The indices of land urbanization and population urbanization in Nanchang showed an upward trend, and therefore the coordination degree in Nanchang increased significantly from 2002 to 2017. (2) The coordinated development of urbanization underwent two stages: disordered and moderately disordered. (3) The urban population proportion and the supporting capability of agricultural production had a positive impact on coordinated development. Meanwhile, the results also show that per capita education expenditures and the per capita public green area had negative impacts on the coordination degree, while economic development and the urban industrial structure were positive contributors to the coordination degree. Finally, this paper proposes that policies should be formulated to achieve coordinated development of urbanization. It can be concluded that the results regarding coordinated development of urbanization can help decision makers formulate effective measures to achieve coordinated development in the future.
Highlights
Urbanization generally refers to both the process of population concentration in urban areas and the transformation of rural areas into urban areas [1]
This paper considers the coordinated development as the dependent variable, economic development, industrial structure, public service and location advantages as independent variables, and builds a multivariate linear regression model to study the influence of coordination degree between land and population in the urbanization process [32]
A coupling coordination model (CCM) of development for urbanization was built based on land and population indicators, and the yearly CD2 of urban sustainability for Nanchang, China, was calculated during the 2002–2017 period
Summary
Urbanization generally refers to both the process of population concentration in urban areas and the transformation of rural areas into urban areas [1]. Since the middle of the 20th century, the coordinated development of land urbanization and population urbanization has received considerable attention [2]. Land 2019, 8, 178 reform and opening-up initiated in the late 1970s, urbanization in China has accelerated rapidly due to farmland conversion (i.e., farmland being converted to land used for construction, etc.) and population migration (i.e., the rural population gradually migrating to urban areas, etc.), which has greatly enhanced the quality of life and economic development [4]. It is estimated that the urbanization growth rate is expected to reach 60% by 2030 and 70% by 2050 [5]. In this context, the coordination of land urbanization and population urbanization has become a hot topic, which is important to achieve coordinated development of urbanization
