题目：Determinants of Greenhouse Gas Emissions from Interconnected Grids in China
摘要：Electricity consumption and transmission are important drivers of greenhouse gas (GHG) emissions. While direct emissions by China’s power sector from the generation side have been widely investigated, driving forces from the electricity consumption perspective and inter-regional electricity transmission connecting the generation and consumption sides have been overlooked to a large extent. This study quantified relative contributions of six factors to changes in GHG emissions from interconnected grids in China during 2008–2015, using structural decomposition analysis based on the quasi input-output model. These six factors include three generation-side factors (i.e., fuel mix of thermal power generation, energy efficiency of thermal power generation, and electricity structure), two demand-side factors (i.e., electricity intensity of gross domestic products(GDP) and GDP), and electricity transmission structure. GDP growth and changes in fuel mix of thermal power generation are two major drivers of increased GHG emission during 2008–2015. In contrast, changes in electricity transmission structure, the decline of electricity intensity of GDP, improvements in energy efficiency of thermal power generation, and changes in electricity structure are major factors offsetting GHG emission increments. Findings of this study can provide generation-side, demand-side, and transmission-side policy implications for GHG mitigation in China’s power sector.
