Cross-border illegal water pollution discharge (CIPD) occurs much frequently due to weak environmental supervision and unclear environmental rights. This paper attempts to explore the impact of cross-border ecological compensation policy (CBEC) on CIPD. By using day-night difference of pollution data at administrative boundary monitoring station, illegal water pollution discharge is calculated. Difference-in-differences-in-differences (DDD) model is used to estimate the impact of CBEC on CIPD. First, DDD results show that CBEC can effectively curb CIPD. Second, environmental regulatory effect, environmental governance effect and environmental awareness effect produced by CBEC are tested. CBEC inhibits CIPD by strengthening media supervision and public pollution reporting in environmental regulatory effect, and reduces CIPD by increasing environmental protection investment and environmental law enforcement efficiency in environmental governance effect, and curbs CIPD by promoting environmental information disclosure and reducing environmental corruption in environmental awareness effect. Third, by further analyzing different stages of CBEC, CIPD generated by environmental action coordination and environmental governance mechanism coordination is highly inhibited. Fourth, CBEC has a stronger inhibition effect on CIPD as upstream region is economically underdeveloped and downstream is economically developed. The conclusion provides policy implications from inter-government coordination for restraining CIPD.
跨境非法水污染排放（CIPD）由于环境监管薄弱和环境权利不明确而频繁发生。本文试图探讨跨境生态补偿政策（CBEC）对 CIPD 的影响。通过利用行政边界监测站的污染数据昼夜差异，计算非法水污染排放。使用差分差分差异（DDD）模型来估计 CBEC 对 CIPD 的影响。首先，DDD 结果表明，CBEC 可以有效遏制 CIPD。其次，检验了 CBEC 产生的环境监管效应、环境治理效应和环境意识效应。CBEC 通过加强媒体监督和公众污染举报来强化环境监管效应，减少 CIPD，通过增加环保投资和提高环境执法效率来减少 CIPD，通过促进环境信息披露和减少环境腐败来遏制 CIPD。第三，通过进一步分析 CBEC 的不同阶段，发现环境行动协调和环境治理机制协调产生的 CIPD 受到高度抑制。第四，CBEC 对 CIPD 的抑制作用更强，因为上游地区经济欠发达，下游地区经济发达。该结论从政府间协调的角度为遏制 CIPD 提供了政策启示。
