The temporal and spatial pattern evolution of land-use carbon emissions in China coastal regions and its response to green economic development

Abstract

Carbon emissions based on land use change have attracted extensive attention from scholars, but the current land use carbon emission accounting model is still relatively rough. Despite the continuous promotion of China’s ecological civilization strategy, whether green economic development promotes carbon emission reduction remains to be studied. This study uses the Exploratory Spatial-temporal Data Analysis (ESTDA) framework system to revise the land-use carbon emission accounting model; it integrates the NDVI adjustment index and systematically analyzes the spatial and temporal patterns and evolutionary path characteristics of carbon emissions from 2000 to 2020 for 130 prefecture-level cities in the eastern coastal region of China, a high carbon emission region. The spatial econometric model is further used to explore the impact of green economy development on carbon emissions. The results show that the spatial distribution of carbon sources and sinks in the eastern coastal cities demonstrates a year-on-year increase during the study period. The spatial distribution of carbon sources is higher in the north than in the south, and the economically developed regions are more elevated than less developed economic areas. Net carbon emissions show prominent spatial clustering characteristics. The south has a more stable internal spatial structure than the north, and the inland has a more stable internal spatial structure than the coast. Green economic development can significantly reduce carbon emission intensity and has a significant spatial spillover effect. The findings imply that policy-makers need to consider the spatial and temporal distribution and spatial correlation of carbon emissions among cities; they can achieve carbon emission reduction by formulating a more reasonable green economy development approach and implementing regional linkages.

Unveiling the spatial-temporal variation of urban land use efficiency of Yangtze River Economic Belt in China under carbon emission constraints

“…In the process of urban land use, undesired outputs such as sewage and exhaust gases were also generated. Therefore, some scholars have included pollutants as undesired outputs in the ULUE evaluation system (Pan et al, 2022;. For example, Wang et al (2022) included carbon emissions as an undesired output in their comparative study of construction land use efficiency in China and United States; similarly measured ULUE in three major urban agglomerations in China using carbon emissions as an undesired output and found that technological progress was the main driver of land use efficiency improvement in each urban agglomeration.…”

Research on the impact of digital economic development level on ecological environment

“…Jiao and Sun 2021) constructed a comprehensive evaluation index system of China's inter-provincial digital economy based on four dimensions: digital foundation, digital application, digital innovation, and digital transformation, and then launched a spatial and temporal heterogeneity of China's inter-provincial digital economy development level and their influencing factors in a spatial SAR analysis (Jiao and Sun, 2021). Pan et al (2021) established an evaluation index system for digital economy development from the four aspects of digital economy infrastructure, digital industrialization, industrial digitalization and digital governance, and used the entropy method for evaluation, finding that the development of digital economy showed an obvious ladder distribution among provinces (Pan et al, 2021). Secondly, the comprehensive evaluation of ecological environment quality.…”

Scenario Prediction of Carbon Emission Peak of Urban Residential Buildings in China’s Coastal Region: A Case of Fujian Province

“…Thus, it can be seen, the carbon peaking and carbon neutralization of China's coastal provinces can not only promote the sustainable development of coastal areas, but also play a significant role in the green and low-carbon transformation of the national economy and the enhancement of international competitiveness [18]. In order to guide the sustainable development of urban residential buildings and provide differentiated governance measures, we consider coastal provinces as the research object and propose the following three issues: To solve these problems, this study proposes a historical carbon emission reduction assessment, carbon emission scenario analysis and low-carbon path research for urban resi-dential buildings in coastal provinces for the first time.…”
