Abstract

Portugal faces water scarcity challenges, yet studies on per-household water consumption are limited. This study aims to address this gap by employing cluster analyses to assess how population trajectories, a previously overlooked aspect, and the regional location influence per-household monthly water consumption across 122 municipalities. Findings highlight higher consumption in the South despite lower prices. Municipalities experiencing population growth and those with long-term population declines show higher per-household water consumption but lower prices. Interestingly, while higher prices correlate with lower consumption, southern municipalities show increased prices without reduced consumption. Clustering reveals slight changes in consumption patterns from 2011 to 2020.

葡萄牙城市家庭用水的聚集模式：区域位置和人口轨迹重要吗？

葡萄牙面临水资源短缺的挑战，但对每户用水量的研究有限。本研究旨在通过采用聚类分析来评估人口轨迹（以前被忽视的一个方面）和区域位置如何影响122个城市的每户每月用水量，从而解决这一差距。调查结果显示，尽管价格较低，但南方的消费量更高。人口增长的城市和长期人口下降的城市，每户用水量较高，但价格较低。有趣的是，虽然较高的价格与较低的消费相关，但南方城市的价格上涨却没有减少消费。聚类揭示了2011年至2020年消费模式的细微变化。

Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
