The Research Of Energy-water Policy Cooperative Control In China Based On System Dynamics

There is an inseparable link between energy and water.As economy continues to develop,the social needs of both resources have grown rapidly,which also poses no small challenge to manage them.At present,the management of these two resources are separated in China,and the energy and water policies are also isolated from each other.In this context,the coordinated management of energy and water is the development trend of future energy and water policy formulation.From the system point of view,this paper integrates energy and water into the same system,constructs a system dynamics model of energy-water nexus in China,and adds policies as exogenous variables to the model.Based on the combing analysis of energy and water policies in China,the paper sets four scenarios and simulates the Chinese energy and water policies under different scenarios.The results show that according to the weakly-constrained policies,as current strength of the policies,it is difficult to achieve the 2020 and 2030 milestone targets set by the government;but the strongly-constrained policies play a significant role in controlling the growth of two resources,and can improve the situation effectively.In addition,the energy-water coordinated control policy restricts the increase of their consumption to a certain extent.As time goes on,this effect will be more and more significant.Therefore,when the government manages these two kinds of resource,it should consider the link between energy and water,strengthen the cooperation between the energy sector and the water sector,and set the energy-water coordinated control policy reasonably,so that it can raise the efficiency of resource management and achieve better policy effect.
