Abstract

Urban scaling laws provide a framework for analyzing how various socio-economic factors such as population size, infrastructure, and innovation interact and influence urban operations. Existing empirical studies on "superlinear scaling" often focus on nonlinear relationships between urban scale growth and indicators like urban functions and economic activities, lacking detailed comparative studies of scaling shifts and scientific explanations of underlying mechanisms, with determinations of influencing factors primarily based on qualitative discussions. Therefore, this paper adopts a superlinear perspective from economic, social, pollution, and energy consumption angles, utilizing least squares method and comparative analysis to identify scaling law deviations in China. The XGBoost + Shap value model method is employed to discern the intrinsic mechanisms influencing these deviations. The study identifies overall trends and two significant turning points in China's superlinear system, where urbanization processes, economic levels, policies, and natural geographic factors variably impact scaling law deviations.

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
