In this study, an economic analysis module was added to the System Dynamics (SD) Water-Food-Energy (WFE) nexus model developed by Ravar et al. (2020) for the Gavkhuni Basin located in central Iran. The case study area has been facing several water-related conflicts due to natural and anthropogenic water scarcity of the basin and severe long-term droughts possibly associated with climate change. To resolve conflicts between environmental, agricultural, industrial and domestic water users, various water consumption management policies were introduced by water user sectors. The consideration of the economic impacts of water consumption management policies can play a key role in efficient and sustainable water resources management. The main purpose of this study was to provide the decision makers with a clear picture of economic impacts and consequences of the water consumption management policies within the framework of WFE nexus assessment. Hidden subsidies provided for water resources and energy carriers were calculated to highlight the importance of the pricing policies. The obtained results for a 10-year simulation period indicated that by implementing the policy suggested by the agriculture sector, not only the average value added (VA) of this sector increased by about 19% but also the average inflow to Gavkhuni wetland rose by about 82%. By applying the policy suggested by the energy sector, the total cost of energy for water decreased by about 30% and total cost of water for energy diminished by about 61%, which contributed to decrease in subsidy for energy and water resources. Furthermore, allocating more water to chemical industries resulted in the improvement of the overall industrial VA. The results also indicated the suitable performance of the developed model in reflecting the cross-sectoral economic consequences of sectoral policies.

在这项研究中，将经济分析模块添加到由Ravar等人开发的系统动力学（SD）水-食品-能源（WFE）关系模型中。（2020年）位于伊朗中部的加夫库尼盆地。由于流域自然和人为的水资源短缺以及可能与气候变化有关的严重的长期干旱，该案例研究区域面临着数个与水有关的冲突。为了解决环境，农业，工业和家庭用水者之间的冲突，用水者部门采取了各种用水管理政策。考虑用水管理政策的经济影响可以在有效和可持续的水资源管理中发挥关键作用。这项研究的主要目的是为决策者提供在WFE关联评估框架内的经济影响和用水管理政策的后果的清晰画面。计算了为水资源和能源载体提供的隐性补贴，以突出定价政策的重要性。在为期10年的模拟期内获得的结果表明，通过实施农业部门建议的政策，不仅该部门的平均增加值（VA）增长了约19％，而且加夫库尼湿地的平均流入量也增加了约19％。 82％。通过采用能源部门建议的政策，用于水的能源总成本降低了约30％，而用于能源的水总成本降低了约61％，这有助于减少对能源和水资源的补贴。此外，向化学工业分配更多的水导致了整体工业VA的提高。结果还表明，所开发的模型在反映部门政策的跨部门经济后果方面具有适当的表现。
