Effectively controlling the carbon emissions intensity of transportation sector (TSCEI) is essential to promote sustainable development industry in China. This study, which builds upon trend analysis, Dagum Gini coefficient, and spatial autocorrelation analysis reveal spatiotemporal differentiation TSCEI, employs both traditional Markov chain analyze dynamic evolution TSCEI forecast its future trend. Furthermore, econometric models are constructed examine convergence characteristics TSCEI. The empirical results following key findings: (1) China has significantly declined, exhibiting a distribution pattern “higher north, lower south; higher west, east”. (2) Inter-regional differences main contributors overall disparities, with provincial positive autocorrelation, primarily characterized by high–high low–low agglomeration. (3) tends gradually shift from high- low-intensity states over time, an equilibrium probability 90.98% for transferring state. Provincial shows significant spillover effects, influenced neighboring provinces’ states. (4) demonstrates at national regional levels, including σ convergence, absolute conditional β energy structure technological progress playing particularly prominent role facilitating towards values. policy implications promoting reducing inequality discussed.

Revealing the City Influence and Its Pattern Using Web Search Data: A New Perspective Through Attention Flow

ISPRS International Journal of Geo-Information, Год журнала: 2025, Номер 14(1), С. 24 - 24

Опубликована: Янв. 10, 2025

City influence is a critical topic in regional studies, reflecting how cities draw attention and exert impact various domains. Understanding city essential for fostering sustainable urban growth. However, existing studies have failed to fully explore the characteristics of reflected by collective behaviors from bottom-up perspective. This study investigates individual search mirror attract, providing insights into their perceived influence. An “attention flow” model developed differentiate between that significant interest those show strong preference these influential hubs. research focuses on China, analyzing spatial patterns factors affect using statistical methods. The results 69% exhibit are geographically closer more cities, emphasizing role geographical proximity shaping digital age. Additionally, reveals power dislocation, partnership, siphoning cities. A consistent relationship identified connected particularly where administrative hubs tend attract nearby focused science education. deepens our understanding shaped relationships, policymakers foster balanced development enhance inter-city cooperation.

Exploring the Transmission Process of Carbon Sequestration Services and Its Applications: A Case Study of Hainan

Forests, Год журнала: 2025, Номер 16(1), С. 136 - 136

Опубликована: Янв. 13, 2025

The pressing need to address climate change and advance global sustainable development has heightened the emphasis on ecosystem services, especially carbon sequestration. This research assesses supply demand dynamics of sequestration services Hainan Island, China, highlighting its significant contributions biodiversity conservation balance. analysis considers spatial distribution interrelation these in light recent land use ecological policy changes. methodology incorporates cover data, Normalized Difference Vegetation Index (NDVI), meteorological soil data. A gravity model is employed elucidate supply–demand relationship for examining flow across different regions identifying connections their intensities. results indicate a notable increase from 2000 2020, particularly central mountainous areas. Conversely, risen, northern plains’ urban areas southern coastal towns. reveals strong interdependence between zones high-demand locales. study underscores disparities Hainan, emphasizing strategic management elements. It provides critical data compensation policies offers insights into roles regional ecosystems mitigation. highlights necessity incorporating land-use planning decision-making foster strengthen resilience.
