The “one size fits all” is not feasible. Instead, regional differentiation management policies should be adopted (Elgin and Oztunali, 2014; Van Rossum and Van De Grift, 2009). To support regional differentiation management, we first evaluated the urgency degrees of emissions reduction of eight provinces and three municipalities (i.e., eleven regions in total). Second, we went through the relationship between economic development and water pollution emissions like the research in 2014 (Zhang and Zou, 2014).We plotted the curves between water pollution emissions intensity and per
capita GDP of eleven regions like the research in 2015 (Farhani and Ozturk, 2015). According to the “curves” for different regions, we determined the development stage of each region and quantified the sustainable performanceusing a coordinationdegree index. The coordination degree index measures the balance between water environment pollutions control and economic development. In the end, we moved forward to specific differentiation managementstrategies built upon development stage and sustainability performance(Lu and Li, 2007; Yong-Huan et al., 2013). Overall, the goal of this study is to provide a comprehensive analysis including urgency quantification, stage classification and coordination degree measurement to understand the policy need in each region for environmental protection and economic development
