PRIVATE PARTICIPATION IN CHINA'S WASTEWATER SERVICE UNDER THE CONSTRAINT OF CHARGE RATE REFORM

This paper develops a model to quantitatively analyse the dependence of private investment on the scale of public investment at different rate levels of wastewater treatment charge. In the meantime, the impacts caused by tax policies on rate level and private sector participation are analysed. In terms of the survey regarding the marketization reform process of the wastewater sector, a summary of the current major public–private partnership (PPP) approaches in China is given in this paper, which reveals that the strategy option also depends on the rate level of the wastewater treatment charge.
