Summary: This paper examines the energy utilization in urbanization development by investigating the factors determining carbon emission intensity and the relationship between urban development level and carbon emission intensity. Using panel data from 2008 to 2019 for the provinces of China, a spatial Durbin model is used to analyze the effect of urbanization on carbon emissions. The results show that the impact of urbanization on carbon emissions follows an inverted N-shaped curve, contrary to conventional studies. The unique characteristics of local urban development in China have significant implications for regional policies. The study suggests better industrial structure adjustment, comprehensive use of natural resources, and efficient coordination of urban planning to control carbon emission intensity and optimize energy resource utilization.

Summary: The new urbanization in China effectively reduces carbon emissions, particularly in terms of per capita carbon emissions. The emission reduction effect of new urbanization policies tends to be enhanced with their implementation, emphasizing the need to accelerate the process of green urbanization, improve infrastructure, optimize industrial structure, and strengthen environmental regulation.

Summary: Burgeoning urbanization poses a significant challenge for global carbon emissions reduction in the future. This study examines the coupling and decoupling relationship between urbanization level (UL) and carbon emissions density (CED) in China at the county level from 2000 to 2020. The results show that both the UL and CED have increased, with hotspots concentrated in eastern China. The decoupling types varied over time, with the most significant transition occurring between expansive negative decoupling, strong decoupling, and strong negative decoupling at the county level.

Summary: Urbanization and land transfer have had a profound impact on the Chinese agricultural sector, leading to an increase in agricultural carbon emissions. This study examines the causal relationship between land transfer, urbanization, and agricultural carbon emissions using panel data from 30 provinces in China. The findings suggest that land transfer can reduce carbon emissions in the long run, while urbanization has a positive effect on agricultural carbon emissions. Short-term impacts are also observed, with both land transfer and urbanization contributing to carbon emissions in insignificant ways. The study highlights the importance of promoting low-carbon agriculture through encouraging land transfer and directing high-quality resources towards green agriculture.

Summary: This study reconstructs the walled cities of China from the 15th to the 19th centuries based on historical documents, creating the China City Wall Areas Dataset (CCWAD) and the China Urban Extent Dataset (CUED). The datasets provide valuable insight into urban land use patterns during the late imperial period in China.

Summary: Urbanization is closely related to energy consumption and carbon emission, as it is the primary driver of changes in energy consumption and the transformation of energy consumption structure. Understanding the interactions among energy consumption, carbon emissions, and urbanization is crucial for promoting coordinated development in China. The empirical results show that urbanization has an inverted U-shaped relationship with total energy consumption and carbon emissions. Continued urbanization will still have a significant impact on energy consumption structure and carbon emission reduction.

Summary: This study examines the impact of energy consumption, economic development, urbanization, and energy consumption on carbon emissions using panel cointegration tests and pooled mean group (PMG-ARDL) approaches. The results reveal that urbanization has no significant effect on environmental quality, while energy usage significantly increases environmental harm. Further research indicates that environmental distortion is a long-term consequence of economic expansion. The responsibility of achieving a green and clean environment lies with government officials and politicians, who should prioritize appropriate energy management, urban planning, and pollution reduction without impeding economic growth.

Summary: This study contributes to the existing literature by proposing a unique decomposition framework for predicting forest carbon sink and analyzing the impact of socioeconomic factors on it. The study finds that FCS and its technical efficiency show an upward trend during the study period, with urbanization and income inequality being the main driving factors. LSTM performs exceptionally well in predicting city-level FCS.

Summary: This study analyzed data from 282 cities in China and found that urbanization plays a crucial role in improving carbon emission performance. There is a U-shaped relationship between urbanization and carbon emission performance, with urbanization having a positive effect beyond a certain point. Additionally, the study found that human capital positively contributes to carbon emission performance, while technological innovation has a inhibiting effect.

Summary: This study analyzed the changes in net primary productivity (NPP) in the Chang-Zhu-Tan urban agglomeration region from 2000 to 2015, as well as the impacts of climate and land-use changes on carbon dynamics. It was found that the total production showed an upward trend, with lower NPP in the middle of the north region compared to other areas. Land-use changes had a positive effect on total production, while the impact of climate changes was relatively minor.

Summary: This study used a spatial panel data model and nighttime light remote sensing data to explore the multiple effects of urbanization on carbon emissions. The results showed that the growth of carbon emissions was closely related to socio-economic development, and high carbon emission areas were mainly concentrated in the northeast and eastern coastal regions. The expansion and fragmentation of urban land, increase in the secondary industry, and consumption behavior were found to contribute to carbon emissions growth, while connectivity between urban lands, rising urban population, and low-carbon awareness of residents could promote carbon mitigation.

Summary: Urban carbon emissions lead to global carbon emissions. Improving urban carbon emissions efficiency (UCEE) in the new-type urbanization (NTU) process is crucial for reducing urban carbon and enhancing sustainable urban development. We investigated the effect and transmission mechanisms of NTU on UCEE in China.

Summary: This study proposes a flexible framework for analyzing carbon balance and investigates the dynamics and heterogeneity of carbon balance in the Middle Reaches of the Yangtze River Urban Agglomeration (MRYRUA) in China. The results show that the region was in a state of carbon deficit between 2000 and 2020, with a significant decrease in growth rate during 2005-2020. Ecological urbanization, population density, and road density were found to have a positive effect on curbing the growth in carbon emissions.
