私人部门进入降低了城市供水行业成本吗?

Can the Private Sector Access Lower the Cost of Urban Water Supply Industry

私人部门进入在一定程度上降低了城市供水行业的成本,但不同城市、不同私人部门之间存在一定的差异。其中,私人部门进入对地级市供水行业成本的降低效应比县级市更为显著;与国际资本进入相比,国内民营资本进入对城市供水行业成本的降低效应更为显著;私人部门进入显著降低了中西部城市供水行业的成本,但对东部城市供水行业成本的降低效应并不显著。研究结论表明,应继续坚持产权多元化的改革思路,同时与东部地区、县级市相比,更应该引导国内民营资本和国际资本进入中西部地区、地级市。
