Theoretical exploration and empirical verification on the spatial coupling of urban shrinkage and aging
Urban shrinkage and aging exhibit complex interactions in population spatial redistribution. However, existing studies largely remain descriptive and correlation-oriented, and lack a systematic theory of spatial coupling and mechanism analysis. This study constructs a spatial coupling theoretical framework centered on the direct and indirect effects of young workforce relocation. Using data from 142 county-level units in the Chengdu-Chongqing Eco…
Urban Shrinkage and Local Government Debt Risk
Urban shrinkage governance and local government debt risk are prominent topics in the current research landscape of sustainable development. Against the backdrop of population divergence and the polarization between urban growth and shrinkage, this study integrated these two phenomena to examine their interrelation using Northeast China as a case study. Employing comparative induction and bivariate models, this study empirically analyzed the impa…

Urban Shrinkage and Urban Vitality Correlation Research in the Three Northeastern Provinces of China
In the global trend of urban shrinkage, urban vitality, as one of the important representations of high-quality urban development, has become a breakthrough. More and more scholars advocate to awaken urban vitality, so as to realize the high-quality development of shrinking cities. This paper takes the municipal districts of 34 cities in the three northeastern provinces of China as study areas, based on the broad concept of urban shrinkage, selec…
The Driving Influence of Multi-Dimensional Urbanization on PM2.5 Concentrations in Africa
Africa's PM 2.5 pollution has become a security hazard, but the understanding of the varying effects of urbanization on driven mechanisms of PM 2.5 concentrations under the rapid urbanization remains largely insufficient. Compared with the direct impact, the spillover effect of urbanization on PM 2.5 concentrations in adjacent regions was underestimated. Urbanization is highly multi-dimensional phenomenon and previous studies have rarely distingu…
The Direct and Spillover Effect of Multi-Dimensional Urbanization on PM2.5 Concentrations
The Chengdu-Chongqing urban agglomeration (CUA) faces considerable air quality concerns, although the situation has improved in the past 15 years. The driving effects of population, land and economic urbanization on PM 2.5 concentrations in the CUA have largely been overlooked in previous studies. The contributions of natural and socio-economic factors to PM 2.5 concentrations have been ignored and the spillover effects of multi-dimensional urban…
The Evolution Characteristics and Influence Mechanism of Chinese Venture Capital Spatial Agglomeration
As an emerging financial entity, venture capital has a significant impact on regional development. However, the research on venture capital mainly focuses on the fields of finance, management, and economics, and fewer researchers study venture capital from the perspective of geography and space. This research explored the evolution characteristics and influence mechanism of Chinese venture capital spatial agglomeration. The innovation of this pap…
