In recent years, environmental problems have attracted attention at home and abroad, so exploring the causes of environmental pollution has become a research content for scholars. The opening of high-speed railway has improved the economic development of China's Yangtze River Delta, and with the economic growth, the construction of high-speed railway has also led to environmental pollution in China's Yangtze River Delta. Therefore, using the data from 41 prefecture-level cities in China's Yangtze River Delta from 2003 to 2020, the SDID model was constructed, and the comprehensive index of environmental pollution was calculated by factor analysis to calculate the impact of high-speed railway construction on environmental pollution in China's Yangtze River Delta. The conclusions are as follows: The opening of high-speed railway significantly reduces the overall pollution level in China's Yangtze River Delta. The opening of high-speed rail has played a role in restraining the environmental pollution of the first and second tier cities and the third and fourth tier cities, but the pollution level of the third and fourth tier cities has decreased significantly.
近年来，环境问题受到国内外的关注，因此探索环境污染的原因成为学者们的研究内容。高速铁路的开通促进了中国长三角地区的经济发展，随着经济的增长，高速铁路的建设也导致了中国长三角地区的环境污染。因此，本文利用中国长三角地区 41 个地级市 2003 年至 2020 年的数据，构建了 SDID 模型，并通过因子分析计算了环境综合污染指数，以计算高速铁路建设对中国长三角地区环境污染的影响。结论如下：高速铁路的开通显著降低了中国长三角地区的整体污染水平。高速铁路的开通对一、二线城市和三、四线城市的环境污染起到了抑制作用，但三、四线城市的污染水平明显下降。
