随着“一带一路”倡议的推进，沿线各国在生态环境保护方面的合作加深，尤其是沿线区域大气环境质量改善的压力，以及我国在大气污染治理方面的经验和技术为我国大气环保产业“走出去”提供了机遇。本研究在诊断“一带一路”沿线国家大气环境现状的基础上，进一步分析各国在大气环境领域的合作情况及需求，对我国在大气环境工程技术与设备、大气环境服务业领域包括大气环境监测、运营等的水平进行综合评估，发掘“走出去”的优势。在综合分析合作形式和优势的基础上，提出包括优先开展大气环境监测技术与设备的合作，鼓励大气环境服务业“搭船出海”，推进大气污染治理技术与工程合作，设立大气环境工程科技重大专项，发挥绿色金融作用保障大气环保产业“走出去”等的促进我国大气环保产业“走出去”的战略对策。

The advancement of the Belt and Road Initiative has enabled the countries along the route to deepen cooperation in ecological and environmental protection. With the increasing pressure for air environment quality improvement along the route, and China's experience and technologies in air pollution control, opportunities are provided for the globalization of China's air environmental protection industry. This study first summarizes the air environment status of countries along the Belt and Road, and then analyzed the cooperation conditions and demands of these countries. It also evaluated the level of air environmental engineering technology and equipment in China, and the level of air environmental services including air environmental monitoring and project operation, thus to explore the advantages for going global. By comprehensive analysis of cooperation approaches and advantages, strategic recommendations are proposed, including prioritizing cooperation in air environmental monitoring technology and equipment, encouraging international cooperation in air environmental services, promoting cooperation in the air pollution control technology and engineering, establishing a major technological project for air environmental engineering, and making full use of green finance.
