“…In addition, PM concentrations (PM 2.5 : 77 μg/m 3 , PM 10 : 123 μg/m 3 ) in 2014 decreased by 76.48% and 50% respectively compared with 2021. This is consistent with the research results of Li et al [92], whose research also pointed out that PM concentration has shown a downward trend in recent years in Chengdu [92]. SO 2 and CO also showed a sharp downward trend, down 68.4% and 50% respectively compared to 2014.…”

The air pollution process and impact mechanism of megacities located in complex terrain are particularly complex. As a typical megacity in China, Chengdu has unique topographical and meteorological conditions, and its pollution control is difficult. This study systematically elucidated the variation characteristics of six criteria air pollutants in Chengdu between 2014 and 2020. Besides, the PM2.5/PM10 and NO2/SO2 ratios were discussed. Furthermore, a detailed analysis of the correlation between air pollutants was carried out. Finally, the collaborative path of carbon reduction and air pollution control is discussed. The results indicated that SO2, PM2.5, PM10 and CO were significantly decreased by 62.9%, 50.8%, 45.5%, and 36.7%, respectively. PM2.5 and O3 compliance rates are very low, and O3 increases with fluctuations. SO2, NO2, CO, PM showed a “U-shaped” seasonal variation, and there was a “seesaw” phenomenon between O3 and PM2.5. The continuous changing trends also found in the ratios of PM2.5/PM10 and NO2/SO2. The results highlight the importance of coordinated reduction of carbon emissions and pollutants in Chengdu. This research can improve the prediction accuracy of air pollution in complex terrain areas under global warming, and improve the understanding of the formation mechanism of air pollution in special terrains around the world.

“…The government implements environmental policy, and forms moderation with energy conservation and emission reduction behavior of logistics enterprises (Cai et al, 2020;Zhang & Ke, 2022). The direct impact of ERs on industrial efficiency is limited (Liu & Guan, 2017;Wu et al, 2022), as mediating factors are required to influence efficiency (Amaya et al, 2021). Ouyang et al (2022) studies that the effect of local ER on innovation efficiency is significantly suppressed by industrial transfer.…”

Road green logistics play a crucial role in promoting a nation’s sustainable economic growth. Environmental regulation (ER) is considered as a major activity to stimulate the development of green logistics. Meanwhile, logistics industry agglomeration (LIA) could enhance the logistics efficiency with reasonable agglomeration. However, the contradiction between them is also becoming important, and the rapid development of logistics has brought huge pressure on the environment. Therefore, the complicated relationship between ER, LIA and road green logistics efficiency(RGLE) needs to be further clarified. Using panel data between 2008 and 2020 in China's 30 provinces, this study measures the RGLE with Super-SBM model. The complex relationships between ER, LIA, and RGLE are then examined with panel regression models. Empirical results indicate that the average RGLE demonstrates a trend of initially declining and then rising, with notable spatial variations. Interestingly, econometric findings confirm that ER does not directly improve RGLE but effectively enhances it through its moderation with LIA. Furthermore, the impact of ER on RGLE exhibits a "U-shaped" relationship under different agglomeration threshold values in the logistics industry. Consequently, this study suggests optimizing LIA and strengthening regional linkage to improve RGLE.

“…In contrast, new energy vehicles mainly use clean energy sources such as electricity and hydrogen, which are more friendly to the environment [2]. Therefore, driven by the dual crises regarding the atmospheric environment and energy security, new energy vehicles, represented by electric vehicles, came into being [4,5]. Under the global consensus of carbon peaking and carbon neutrality, governments encourage people to use new energy vehicles, which have gradually become mainstream [3].…”

Under the global consensus of carbon peaking and carbon neutrality, new energy vehicles have gradually become mainstream, driven by the dual crises regarding the atmospheric environment and energy security. When choosing new energy vehicles, consumers prefer to browse the post-purchase reviews and star ratings of various new energy vehicles on platforms such as DCar.com. However, it is easy for consumers to become lost in the high-star text reviews and mismatched reviews. To solve the above two issues, this study selected nine new energy vehicles and used a multi-attribute decision making method to rank the vehicles. We first designed adjustment rules based on star ratings and text reviews to cope with the issue of high star ratings but negative text reviews. Secondly, we classified consumers and recommended the optimal alternative for each type of consumer to deal with the issue of mismatched demands between review writers and viewers. Finally, this study compared the ranking results with the sales charts of the past year to verify the feasibility of the proposed method initially. The feasibility and stability of the proposed method were further verified through comparative and sensitivity analyses.
