PM pollution has produced adverse effects all over the world, especially in fast-developing China. PM pollution in China is widespread and serious, which has aroused widespread concern of the government, the public and scholars. This paper evaluates the evolution trend and spatial pattern of PM pollution in China based on the data of 281 prefecture-level cities in China from 2007 to 2017, and reveals the pollution situation of PM and its relationship with industrial restructuring and technological progress by using spatial dynamic panel model. The results show that China's PM pollution has significant path dependence and spatial correlation, and the industrial restructuring and technological progress have significant positive effects on alleviating PM pollution. As a decomposition item of technological progress, technical change effectively alleviates PM pollution. Another important discovery is that the interaction between industrial restructuring and technological progress will aggravate PM pollution. Finally, in order to effectively improve China's air quality, while advocating the Chinese government to pursue high-quality development, this paper puts forward a regional joint prevention mechanism.
PM 污染在世界各地产生了不良影响，尤其是在中国这个快速发展的国家。中国的 PM 污染广泛而严重，引起了政府、公众和学者的广泛关注。本文基于 2007 年至 2017 年中国 281 个地级城市的数据，评估了中国 PM 污染的演变趋势和空间格局，并通过空间动态面板模型揭示了 PM 污染状况及其与产业结构调整和技术进步的关系。结果表明，中国的 PM 污染具有显著的路径依赖性和空间相关性，产业结构调整和技术进步对缓解 PM 污染具有显著的正向影响。作为技术进步的分解项，技术变化有效地缓解了 PM 污染。另一个重要发现是，产业结构调整和技术进步的相互作用会加剧 PM 污染。最后，为了有效改善中国的空气质量，本文在倡导中国政府追求高质量发展的同时，提出了一个区域联合防治机制。
