摘　　要：随着工业化和城市化的发展,生态环境污染日渐加剧,为此地方政府逐渐加强环境规制水平,以期在经济发展与生态保护之间寻求平衡。学术界与政府决策人员担心加强环境规制虽能有效控制环境污染,但亦会使企业负担加重,甚至使企业向环境规制较弱的区域转移,从而陷入环境改善而经济发展停滞的困境。因此,选取中国珠江流域云南、贵州、广西、广东、湖南、江西6个省的58个地级市,2004~2019年的面板数据为实证研究的样本,通过构建计量经济模型来研究环境规制强度对水污染治理存在怎样的影响,在此基础上进行中介效应检验,分别考虑工业企业的技术进步和区域产业集聚是否会影响环境规制与水污染治理之间的关系。研究发现环境规制强度对水污染指数具有显著的负向影响,环境规制会限制技术效率,而技术效率被限制之后,整体工业企业由于生产方面受到一定的影响,从而会降低水污染指数,环境规制会促进产业集聚,而产业集聚被激发之后,整体企业由于生产方面受到集聚效应,从而会降低水污染指数。由此建议有关部门完善环境规制手段,使环境监管和技术进步在本质上保持一致,发展差异型环境规制工具。With the development of industrialization and urbanization, ecological environmental pollution is increasingly aggravated, so local governments gradually strengthen the level of environmental regulation, in order to seek a balance between economic development and ecological protection. Academics and government policymakers worry that strengthening environmental regulation can effectively control environmental pollution, but it will also increase the burden on enterprises, and even make enterprises move to regions with weak environmental regulation, thus falling into the dilemma of environmental improvement and economic stagnation. Afterwards, taking China’s Pearl River basin of Yunnan, Guizhou, Guangxi, Guangdong, Hunan, Jiangxisix provinces of 58 city, 2004~2019 panel data for empirical research samples, the econometric model is constructed to study environmental regulation intensity influence on how water pollution governance exists, on the basis of the intermediary effect of inspection. Whether the technological progress of industrial enterprises and regional industrial agglomeration will affect the relationship between environmental regulation and water pollution control is considered respectively. Study found that: the intensity of environmental regulation on water pollution index has obvious negative impact;environmental regulation will limit the technical efficiency;technical efficiency is limited;the overall industrial enterprises as affected by a certain production, thus can reduce water pollution index;environmental regulation will promote industrial agglomeration;and industrial agglomeration is triggered;for the overall enterprise, because production is crowding effect, this will lower the water pollution index. Therefore, it is suggested that the relevant departments should improve the means of environmental regulation, make the environmental regulation and technological progress consistent in essence, and develop differential environmental regulation tools.
