Investigates regional integration's impact on the ice-snow economy in urban agglomerations, suggesting new strategies for sustainable development.

The aim is to explore how regional integration affects the development of the ice-snow economy in China, focusing on spatial spillover effects.
Constructed a multidimensional ice-snow economy index covering 207 cities from 2013 to 2024
Employed fixed-effects panel models and spatial Durbin models to analyze data
Controlled for spatial heterogeneity and examined nonlinear relationships
An inverted U-shaped relationship exists between regional integration and ice-snow economy growth
Moderate integration enhances growth, while excessive integration leads to resource crowding
Identified significant spatial spillover effects in core-periphery structures, with varying outcomes across different regions

Zhou et al. (2026) studied this question.
