“…For example, the current flue gas standard for PM 2.5 of 30 mg/m 3 in cement industrial 57 should be lowered by 20% to meet the strict ambient air quality. To sum up, when industrial parks formulate air control policies, the promotion of advanced end-of-pipe treatment technologies should be a key measure to improve air quality at the national or urban regional scale 58 , 59 . For the smooth promotion of this measure, the government could put forward some mandatory requirements.…”

Industrial parks contribute greatly to China’s economic development while emitting huge air pollutants. It is necessary to study the characteristics of air pollutant emissions in industrial parks. In this study, emission inventories for 11 industrial parks were established. Meanwhile, the source emission and spatial distribution characteristics of the industrial park were analyzed. The cluster analysis was used to classify these parks into “4Hs”, “Mixed” and “4Ls” parks. “4Hs”, “Mixed” and “4Ls” represent that the levels of energy intensity, economic proportion of energy-intensive industries, coal proportion and pollution performance value are high, medium and low in turn. Then three emission reduction measures were set up to estimate the emission reduction potential and environmental impacts. The results show that: (1) the emissions of SO2, NOx, CO, PM10, PM2.5, VOCs and NH3 of 11 industrial parks in 2017 were 11.2, 23.1, 30.8, 8.3, 3.5, 5.1, and 1.1 kt, respectively. (2) Power plants were the largest source of SO2 and NOx emissions, and industrial processes were the largest emission source of CO, PM10, PM2.5, VOCs and NH3. (3) “4Hs” parks with traditional energy-intensive industries as the leading industries should be the emphasis of air pollutant emission reduction. (4) Through the optimal emission reduction measures, SO2, NOx, PM10, PM2.5 and VOCs were reduced by 81, 46, 51, 46 and 77%, respectively. Environmental impact reductions include 1.6 kt SO2eq acidified gas emissions, 1.4 kt PO43−eq eutrophication substances, 4.2 kt PM10eq atmospheric particulate emissions, 7.0 kt 1,4-DCEeq human toxic substances, and 5.2 kt PM2.5 eq breathing Inorganic. This study is helpful to understand the characteristics of air pollutants emissions in industrial parks and promotes the proposal and implementation of air pollutant emissions reduction strategies.

“…Sulfur dioxide is a typical pollutant of air pollution. China's energy consumption structure is based on coal and oil that produce sulfur dioxide and other harmful gases [36]. Due to the lack of a widely recognized indicator, SO 2 was selected as a representative indicator of air pollution [37].…”

Industrial co-agglomeration plays a significant role in the moving up of the manufacturing industry in the value chain and in transforming China from a manufacturing giant into a world manufacturing power. This study establishes a co-aggregation index to explore spatio-temporal changes of the co-agglomeration between manufacturing and producer services in 30 provinces of China from 2004 to 2019. Furthermore, we use spatial Durbin model to analyze the impact of industrial co-agglomeration on air pollution reduction. We find that (1) the co-agglomeration index varies remarkably at spatio-temporal scale; (2) high co-agglomeration index is mainly distributed in eastern and central China, while low co-agglomeration index is mainly located in the western region; (3) the co-agglomeration index presents a cluster pattern among provinces, with the cluster of high value in eastern China and the cluster of low value in western China; and (4) the co-agglomeration between manufacturing and producer services is proven effetely to reduce air pollution, which is accompanied with spatial spillover effect. We also provided policy implications in line with diverse industries, multi hierarchies, and different regions, promoting the coordination of manufacturing and producer services and improving air quality.

“…Those four cities have political and economical advantages when coping with air pollution, due to their larger scales and higher administrative ranks [20]. The "air pollution" problem has aroused earliest attentions, and the energy-generation technology has been innovated with the fastest speed in these four cities among the whole country [21]. More importantly, Beijing, Tianjin, Chongqing and Shanghai represent different geography and climate conditions including typical north-inland, north-coastal, south-inland and south-coastal types in China, respectively [11].…”

“…In fact, we find no relationship of air pollution (particularly PM 2.5 and PM 10 ) with other power output (total power output minus thermal power output), which might be also hinted in our results tables (the estimated coefficient of thermal power output is much higher than total power output for most pollutants), except SO 2 , NO 2 and O 3 . As to SO 2 , existing research findings that air pollution net SO 2 emission intensity of thermal power generation has dropped significantly since 2006 might be possible causes [21]. The NO 2 results indicate that even the renewable power generation, referring hydroelectric power, nuclear power, wind power and solar power, may lead to some air pollution in different ways.…”

We estimate impacts of electricity generation (total power output and thermal power output) on air pollution (air quality index (AQI) and six criteria air pollutants), with a particular emphasis on industry and city heterogeneity. To identify this relationship, we combine detailed monthly data on electricity production, air pollution, economy and weather for a six-year period in four biggest cities in China. Our fundamental identification strategy employs Ordinary Least Squares Regression of panel data with city–month fixed effects and addresses confounding variations between electricity generation and economy or weather conditions. We find that one unit (100 million kwh) increase in power output is associated with a 0.3-unit (representing value) increase in AQI, nearly all of which is driven by increases in thermal power output. We notice a robust positive impact of increased electricity generation (specifically thermal power output) on PM2.5 and PM10, also positive relationships between increases in other power output (total power output minus thermal power output) and SO2, NO2, while changes in power output have no statistically significant effect on CO and O3. The heterogeneous pollution effects of electricity generation are present in specific cities with different weather conditions. The results indicate that a reduction policy in power industry differentiating among cities might enhance effectiveness by considering each city’s particular backgrounds, a previously overlooked aspect associated with pollution reduction policies.
