Research on carbon emission differences decomposition and spatial heterogeneity pattern of China’s eight economic regions

Abstract

To explore the sources of regional carbon emission differences and the evolution characteristics of spatial heterogeneity pattern, this paper first calculates the corresponding carbon emissions according to the relevant statistical data of eight economic regions in China from 2005 to 2019. It analyzes the overall differences and temporal and spatial evolution characteristics of regional carbon emissions combined with the visualization method of GIS. Then, the total carbon emission difference is decomposed by the Theil index to find out the primary sources affecting the regional carbon emission difference. Finally, the driving factors affecting the spatial heterogeneity pattern of regional carbon emissions are studied with the help of the Geodetector method. The results show that (1) significant differences in carbon emissions among China’s eight economic regions. The contribution rate of inter-regional and intra-regional differences of carbon emissions in different regions to the overall carbon emission difference is diverse. (2) Regional carbon emissions are affected by single driving factors and the interaction of two driving factors. The interaction has an increasing impact on the determinant of regional carbon emission spatial differentiation. (3) The factor detection results and interaction detection results, respectively, show that the level of energy consumption, industrialization, and technological development has always been the main driving factors affecting the spatial heterogeneity pattern of regional carbon emissions, and the critical interaction factors have multiple spatial superposition interaction effects. Therefore, regional carbon emission reduction should consider the national strategic objectives and own regional characteristics and implement differentiated emission reduction schemes.

Carbon emission quota allocation of high energy consumption industries in undeveloped areas – A case study of Inner Mongolia Autonomous Region

“…The feasibility requires that the allocation of quotas is economically, technically, and managerially feasible. Enforceability means that the allocation scheme and the final result can be recognized by the allocation object, taking into account the historical emission level of each industry and the sustainable and stable development of the industry in the future ( Zhang et al, 2022a , Zhang et al, 2022b ). The principle of sustainable development is an important guarantee for the implementation of allocation programs.…”

Decoupling between Economic Growth and Carbon Emissions: Based on Four Major Regions in China

“…This would have a double negative impact on China’s carbon market. The risk transmission between carbon emissions and the electricity market is rooted in the oil market, where uncertainty in the oil market affects the price of electricity to a certain extent [ 51 ]. The high or low price of electricity affects the use of energy types for power generation, which could increase or decrease carbon emissions.…”

Coupling Coordination and Spatiotemporal Dynamic Evolution between Agricultural Carbon Emissions and Agricultural Modernization in China 2010–2020

“…Secondly, synergistic cooperation among regions is essential to break down barriers of agricultural carbon emission reduction in the process of agricultural modernization. Based on the resource endowment of different regions [41], governmental or nongovernmental organizations can establish inter-regional carbon market trading mechanisms and carry out inter-regional cooperation through market mechanisms in achieving agricultural carbon emission reduction [42]. Thirdly, encouraging agricultural producers and consumers to participate in green emission reduction programs cannot be overemphasized.…”
