Article Synopsis
- Strategic coordination between urbanization and carbon emission efficiency (CEE) is crucial for sustainable urban planning, with research using models to assess how these factors influence each other in 106 countries from 2005 to 2020.
- The study finds that while global CEE is decreasing, it is unevenly distributed, with wealthier countries in Europe showing higher CEE compared to lower-income regions in Asia and Africa.
- The research indicates fluctuations in the coupled coordination degree (CCD) of urbanization and CEE, with suggestions for improving coordination through urban electrification and policy changes aimed at better integrating these two areas.
Article Synopsis
- - China's economic development has resulted in substantial emissions and environmental damage, making green development essential for sustainable growth and addressing these challenges.
- - A study evaluates the green development efficiency of 30 Chinese provinces using a specific index system and the Supe-SBM model, revealing significant spatial and temporal differences in efficiency levels.
- - Findings indicate that the eastern region has the highest green development efficiency, while central provinces lag behind and show a downward trend; factors like technological progress and urbanization positively influence efficiency, whereas industrial structure and financial development have negative impacts.
Article Synopsis
- Effective management of water resources is crucial for a country's economic development, and the study focuses on assessing the water resource green efficiency (CWRGE) across 108 cities in the Yangtze River Economic Belt from 2006 to 2021 using the Super-SBM model.
- Overall, the CWRGE has not reached effective levels, showing a fluctuating "W"-shaped trend, with only seven cities achieving effective data envelopment analysis rankings.
- The study highlights disparities in CWRGE based on city size and location, revealing that larger cities perform better, with downstream cities exhibiting the highest efficiencies, while various factors like economic development and industrial scale positively influence CWRGE, contrary to foreign direct investment and environmental regulation, which
Article Synopsis
- - China's rapid urbanization is straining land resources, raising issues about how to effectively use limited land for social, economic, and environmental benefits.
- - An assessment of green land use efficiency in cities along the Yangtze River from 2005 to 2019 revealed overall inefficiency, with megacities performing best and upstream regions showing lower efficiency levels.
- - Factors like population density and environmental regulations positively influence urban land green use efficiency, while economic development and land use scale can hinder it; recommendations for improvement are provided based on these findings.
Article Synopsis
- - The global climate issue is worsening due to high carbon dioxide emissions, presenting a challenge for countries to reduce emissions while fostering economic development.
- - The study analyzes carbon emission efficiency across 136 countries from 2000 to 2019, finding significant disparities, with only a few countries, mostly in Europe, achieving high efficiency while many in Asia and Africa lag significantly behind.
- - Utilizing the Tobit model, the research identifies factors influencing carbon emission efficiency, highlighting that developed countries perform better than developing ones, which aligns with the environmental Kuznets curve theory.
Article Synopsis
- - The study focuses on evaluating the energy efficiency of China's construction industry in the Yangtze River Economic Belt (YREB) using the Super-EBM model to assess green total-factor energy efficiency (CIGTFEE) from 2003 to 2018, amidst goals for carbon neutrality.
- - Results reveal a general growth in CIGTFEE over the period, with varying trends across different regions: downstream areas peaked until 2006, while midstream followed an "M" shape and upstream regions displayed an inverted U-shape; significant spatial agglomeration was also observed.
- - Key drivers of CIGTFEE include economic growth, energy structure, and human capital, with urbanization having a negative effect
