Mitigation Strategy Analysis of Aggregate Industrial NO,and NO,Intensity in China Using Structural Decomposition Analysis Framework
Economic growth has brought challenges to ecological and environmental sustainable development.NOx governance has become one of the severe challenges of China's social and economic development,especially the industrial sources.Although the absolute change in aggregate NOx emissions is often used by researchers and policymakers to measure environmental performance,very few studies systematically track the drivers of NOx emission/intensity changes with structural decomposition analysis(SDA).The embodied industrial NOx emission/intensity is estimated by final demand category at the aggregate and sector levels,and the total NOx emission/intensity is decomposed using additive and multiplicative SDA under the input-output framework.The results show that the embodied emissions/intensity were significantly reduced at the final demand category level;investment was the main contributor to China's NOx emission/intensity,followed by household consumption.The emission intensity effect is the main driver(91.69％)of NOx emission/intensity reduction,and the domestic Leontief structure effect is the catalyst for the emission intensity effect.The final demand categories presents a blocking effect.At the sector level,the aggregate embodied NOx emission is mainly contributed by construction(49.26％),and the aggregate embodied Value Added is mainly contributed by service(44.90％).The emission efficiency improvement of the sectors"Production and supply of electricity and heating power","Non-metal minerals products"and"Smelting and pressing of ferrous metals"make these sectors the main contributors to the decline in the total aggregate embodied emission intensity.Finally,the mitigation strategy is discussed from a win-win perspective balancing economic growth and environmental protection,which provides a theoretical basis for future NOx governance.
