Regional water consumption control based on technical efficiency of water resources utilization
At present,the indices of water utilization efficiency of water consumption control are simple,and the water users' inputs and outputs are not taken into account.The concept and content of technical efficiency of water resources utilization were analyzed.The idea of regional water consumption control based on the technical efficiency of water utilization is proposed,and an objective model for regional water consumption control was developed.Xuzhou City was considered a case study for demonstration analysis.The results show that it is feasible to divide water consumption control into two levels,the control water quantity and objective water quantity.It is also feasible to calculate the technical efficiency of water resources utilization with a stochastic frontier production function,and to calculate the objective water quantity of regional water consumption as well.
