摘　　要：本文利用2005-2013年中国34个工业行业的面板数据,检验企业产权多元化对水环境污染的影响。总体看来,行业国有化程度越高,产权多元化水平越低,水环境污染排放强度越低。门槛效应检验发现,不论国有化程度处于何种水平,国有化程度的提高都有助于改善环境,只是程度有些差异。当污染排放强度较低时,产权多元化有助于降低污染排放强度,而当污染排放强度较高时,国有化才是缓解环境污染的最优选择。因此,在推进国有企业混合所有制改革中,不能放松国有企业的环保责任,更不能为了经济保值而放弃生态环境"保值"。Using industrial panel data of 34 industries from 2005 to 2013 in China, the relationship between partial privatization and water environmental pollution was examined. Overall, the higher the state owned proportion is, the lower the level of partial privatization is, and the lower the density of water pollution emission will be. The result of threshold effect indicated that, regardless of the state- owned proportion, the increasing of state owned proportion would be helpful for environmental improvement. The only difference was the degree. When the water pollution density is low, the partial privatization was good for water pollution density reduction. However, when the water pollution density is high, nationalization was the best choice to alleviate environmental pollution. Thus, the environmental protection responsibility of state-owned corporations should not be ignored in the process of reform. Also, we should not give up the ecological environment for economic value.
