自2000年以来，中国实施了“西部大开发战略”，支持西部地区经济社会发展。然而，发展的进步似乎是以空气质量为代价的。扭转这一趋势对公众和中国政府来说都是当务之急，中国政府多次强调承诺不会重蹈发达国家“先污染、后治理”的覆辙。本研究利用官方统计信息和同行评审文献数据，估算了中国西部最大经济体四川省各经济部门的细颗粒物（PM2.5）、二氧化硫（SO2）和氮氧化物（NOX）排放量，并利用结构分解分析测算了2002年至2012年不同社会经济驱动力对排放变化的贡献。结果表明，PM2.5和SO2的效率增益超过了排放增量。经济扩张的影响，而对于NOX来说，效率的贡献仍然落后于经济规模的影响。大规模的基础设施投资和房地产业的快速扩张提振了四川经济，但也加剧了区域空气污染。总体而言，排放效率更高、材料效率更高且结构优化的生产系统是首要的污染减排战略。此外，应该优化GDP结构，更充分地满足公众不断变化的消费需求，而不是仅仅投资于建筑业等高利润但高排放的行业。 (C) 2018 Elsevier Ltd. 保留所有权利。
China has implemented the "Western Development Strategy" to support the socioeconomic development of its western region since 2000. The development progress, however, appears to come at the cost of air quality. Reversing this trend is imperative for both the public and the Chinese government, which has frequently emphasized its commitment to not repeat the "pollution first and then treatment" experience of developed countries. With official statistical information and data from peer-reviewed literature, this study estimates the fine particles (PM2.5), sulfur dioxide (SO2), and nitrogen oxide (NOX) emissions of the economic sectors of Sichuan province, which is the largest economy in western China, and uses structural decomposition analysis to measure the contribution of different socioeconomic driving forces to the emissions change from 2002 to 2012. The results show that, the efficiency gains of PM2.5 and SO2 have prevailed over the emissions-increasing effect of economic expansion, while for NOX, the efficiency contribution still lags behind the impact of economic scale. The large-scale infrastructure investment and the rapid expansion of the real estate sector boosted Sichuan's economy but exacerbated regional air pollution. Overall, a more emissions-efficient, material-efficient and structurally-optimized production system is the overarching pollution reduction strategy. In addition, the GDP structure should be optimized to more adequately meet the changing consumption demands of the public instead of merely investing in profitable but emissions-heavy sectors such as construction.
