Abstract
The Beijing–Tianjin–Hebei urban agglomeration (BTH) is striving to realize the transformation process from a low-efficiency to a high-quality development mode; however, it still has problems regarding reducing energy consumption and ecological environment pressure. Based on panel data from 2013 to 2017, this paper proposes an evaluation index system based on BTH’s “environmental protection–industrial structure–urbanization” system. In the course of applying the coupling degree model (CDM) and the coupling coordination degree model (CCDM) with exploratory spatial data analysis (ESDA) methods, this paper discusses the spatiotemporal process, development level, and spatial agglomeration characteristics of the environmental protection–industrial structure–urbanization system in each city of the BTH area. The findings reveal that the coupling degree of the BTH system is gradually increasing, and that the development level of the BTH subsystem is unbalanced: the coupling coordination level of BTH shows a positive evolution process; however, it is in a stage of low-level collaborative development, and there are obvious differences in the level of BTH coupling coordination in space, revealing the convergence of low–high and high–low types. This paper concludes by putting forward the strategy of optimizing the regional spatial pattern of urban agglomeration and implementing integrated development in order to achieve the desired coupling and coordination effects.
Highlights
In recent years, changes in global industrial structure and the acceleration of factor flow have led to continuous improvements in the world’s urbanization level [1,2]
The coupling degree model (CDM) describes the degree of coordination among the three subsystems of environmental protection, industrial structure, and urbanization; it is significant in relation to constraining the development of environmental protection, industrial structure, and urbanization to promote the coordinated development of the three systems
Industrial structure–urbanization system has gradually evolved in an orderly direction from 2013 to 2017
Summary
Changes in global industrial structure and the acceleration of factor flow have led to continuous improvements in the world’s urbanization level [1,2]. Environmental problems such as energy consumption and particulate air pollution caused by population agglomeration have had a significant impact on the world’s sustainable development [3,4]. The relationship between environmental protection, industrial structure, and urbanization will continue to be an issue of great concern for future economic growth
