Considering the situation of the frequent turnover of Chinese environmental protection officials (EPOT), this paper analyzes its impact on transboundary water pollution. The results show that EPOT can reduce transboundary pollution. EPOT can reduce the concentration of DO by 0.261 and NH3-N by 0.167 in the downstream river. And the impact shows a first strong and then weak change over time. EPOT can restrain transboundary pollution by reducing the production of polluting enterprises and promoting public pollution reporting, and it aggravates transboundary pollution by reducing environmental law enforcement and collaborative governance. In addition, the impact of EPOT on transboundary pollution has a distance effect. Within the regulatory distance of 50 km, EPOT has strong inhibition on transboundary pollution. When the governor and the environmental protection official (EPO) change tenure at the same time, the inhibition of transboundary pollution is the strongest. In addition, EPOs from the central government and with working experience in environmental protection departments can control transboundary pollution better.
考虑到中国环保官员（EPOT）频繁更替的情况，本文分析了其对跨界水污染的影响。结果表明，EPOT 可以减少跨界污染。EPOT 可以使下游河流中的 DO 浓度降低 0.261，NH3-N 浓度降低 0.167。并且这种影响随着时间的推移呈现出先强后弱的变化趋势。EPOT 可以通过减少污染企业的生产和促进公众污染举报来抑制跨界污染，同时也会通过减少环境执法和协作治理来加剧跨界污染。此外，EPOT 对跨界污染的影响具有距离效应。在 50 公里的监管距离内，EPOT 对跨界污染有较强的抑制作用。当省长和环保官员（EPO）同时更换任期时，对跨界污染的抑制作用最强。此外，来自中央政府的 EPO 以及具有环保部门工作经验的 EPO 可以更好地控制跨界污染。
