摘　　要：从时空角度研究长江经济带的水环境污染状况,探究异质性环境规制对水环境污染的影响,为促进水资源合理利用与绿色发展提供参考。基于2009—2019年长江经济带11个省市的面板数据,研究长江经济带水环境污染的时空特征,用Moran’s I指数研究水环境污染的空间自相关性,再通过空间杜宾模型探究异质性环境规制对水环境污染的空间溢出效应。研究表明:(1)总体来看,长江经济带水环境污染呈上升趋势,其中上游地区水环境污染增速较快,下游和中游地区有所放缓,水环境污染得到一定控制;(2)长江经济带水环境污染严重程度具有明显的空间特征,呈现出下游>中游>上游的趋势;(3)从异质性角度来看,命令控制型环境规制能显著抑制水环境污染,在经济矩阵下效果最为显著,市场激励型环境规制具有显著负向作用,而公众自愿型环境规制的作用并不明显;(4)从溢出效应来看,命令控制型环境规制对周围省市的水环境污染具有负向的空间溢出效应,市场激励型环境规制也会减轻周围省市的水环境污染严重程度,但没有命令控制型环境规制效果明显,公众自愿型环境规制效果不显著。目前长江经济带水环境污染状况仍不容乐观,需要进一步加强管控。虽然命令控制型环境规制对水环境污染治理效果最好,但公众参与也应该提上日程。各地要因地制宜,选择合适的方式来治理,此外还需要建立空间意识,加强联合治理。This paper studies the current water pollution in the Yangtze River Economic Belt temporally and spatially,explores the impacts of heterogeneous environmental regulations on water environmental pollution and provides references for promoting appropriate use of water resources and green development.Based on eleven provinces’panel data from 2009 to 2019,this paper studies the temporal-spatial features of water environmental pollution,and uses Moran’s Index to analyze its spatial auto-correlation,and applies spatial Dobbin model to elaborate the spatial overflowing effect of heterogeneous environmental regulations.The results show that water environmental pollution discharge is rising,faster in the upper-reach,slower in the middle-and down-reach under certain controls.The water environmental pollution is of clear spatial distribution showing a decreasing trend from down-reach to upper-reach.Command-controlling regulations can obviously restrain water environmental pollution discharge,especially under the economic matrix;however,market-stimulated environmental regulations do the contrast,and public-volunteer environmental regulations do little.Command-controlling environmental regulations have a negative spatial overflowing effect on water environmental pollution of neighboring provinces/cities;market-stimulated environmental regulations do less,and public-volunteer environmental regulations do little,which means public involvement should be intensified.It concludes that the Yangtze River Economic Belt is still not good in water environmental pollution,which needs further controls.Although command-controlling regulations are the best means to curb water environmental pollution,public involvement shall also be taken into consideration.Appropriate approaches vary with areas.This paper presents suggestions on cultivating space awareness and boosting collaborative controls.
