Abstract
It is of great significance to explore the dynamic coupling relationship between industrial integration and urban land-use efficiency (ULUE) in order to promote high-quality urban development. This paper presents a system for evaluating industrial integration and ULUE which combines the internal theoretical relationships between the two. Based on this system, this paper analyzes the evolution process and the mechanism behind the coupling coordination relationship between industrial integration and ULUE with the help of the coupling coordination model, nonparametric kernel density estimation, and the geographical detector method. The results indicate the following: (1) The coupling coordination relationship between industrial integration and ULUE in the Yangtze River Economic Zone experienced an overall steady increase during the investigation period. However, there were great spatial differences in the coupling coordination relationship among cities. (2) The lag of the industrial integration level was the key area of resistance to the improvement of the coupling coordination level. (3) The interaction between industrial integration and ULUE in the Yangtze River Economic Zone was very significant. In particular, the impact of industrial agglomeration and factor flow on the ULUE and the impact of land on industrial integration in terms of ecological environment were prominent. In addition, the interaction of different detection factors was mainly manifested as a double factor enhancement effect and nonlinear enhancement effect.
Highlights
The direction, structure, and layout of industrial development changes and affects the scale and speed of industrial integration development. When it comes to policy effects, means of macro-control, such as land-use control and Whenare it comes to policy means of macro-control, as land-use control planning, important policyeffects, tools that promote the process of such industrial integration
According to the above theoretical analysis, this study regards industrial integration is, from the integration of industrial layout characterized by spatial physical linkages as a vertical development process from superficial integration to deep integration, that is, between regions to the integration of industrial factors flow with this interaction as the from the integration of industrial layout characterized by spatial physical linkages becarrier within the region [48]
In comparison to the existing research, this paper may contribute to the exploration of the coupling and coordination mechanism between industrial integration and urban land-use efficiency (ULUE), as well as the construction of a comprehensive evaluation system for industrial integration and a green evaluation system for ULUE based on multi-objective constraints
Summary
Ellison and Glaeser argue that income-increasing technologies and spillover effects exist in industrial agglomeration zones in theory [18] These effects can lead to economic externalities by transforming industrial structures into specialized ones or diversifying others in order to improve the urban land-use efficiency [19]. Based on the aforementioned ideas, this paper includes 107 cities at prefecture level and above in the Yangtze River Economic Zone as its research subjects, re-examines the level of industrial integration and ULUE of each city in the region, and uses the coupling coordination degree model and nonparametric kernel density estimation method to analyze the current situation and dynamic evolution of the coupling coordination relationship between the two.
