Efficiency and Equity Balanced Water Pollutant Emission Aggregate Allocation for Jiangsu Province
Regional total water pollutant allocation is the key to inter-regional equitable coordination and efficient economic development.In order to balance efficiency and equity,the optimal efficiency solution with the smallest distance from the ideal equity solution s taken as the final solution,thus the total emissions allocation model s constructed and the total COD allocation scheme s calculated for each prefecture-level city for the"14th Five-Year Plan".Results show that:(1)Yancheng and Xuzhou,which halarger historical COD emissions,allocated 14.2％and 12.1％of Jiangsu Province's emissions,which manifest historical and developmental equity,and they b18.5％and 10.8％of the province's emissions reduction quota,evidencing the principle of equity of"whoever pollutes governs";(2)Wuxi and Changzhou,higher economical level and unit emission output,in line with the requirement of efficiency prioritization,as the final scheme of emission allocation s larger than the equity scheme.Based on this,Jiangsu Province prefecture-level cities divided into four categories based on COD emission reduction rate and per capita GDP,so as to separately explore and discuss the path of sustainable development.
