摘要

基于2022年1月至2023年6月奥克兰22,362户家庭的月度用水数据，本研究通过差异中的差异（DID）模型调查了智能电表对家庭用水的影响。本文发现，用智能水表取代传统水表导致住宅用水量增加了约4%。然而，这一增长被安装了提供实时用水信息和漏水警报的移动应用程序所抵消。这些特点促使居民更合理地管理用水，有可能使平均用水量减少5%左右。此外，异质性分析显示，安装智能水表和移动应用程序导致基线用水量低的家庭用水量增加，而基线用水量高的家庭用水量减少。实证研究结果为智能电表的实施提供了重要见解，并为政策制定者提供了实用建议。

The impact of smart meter programmes on household water consumption: evidence from New Zealand

Based on monthly water use data from 22,362 households in Auckland from January 2022 to June 2023, this study investigates the effect of smart meters on household water use through a Difference-in-Differences (DID) model. This paper finds that replacing conventional meters with smart water meters resulted in an increase in measured residential water use by about 4 %. However, this increase was offset by the installation of mobile apps that provide real-time water usage information and leakage alerts. Such features have motivated residents to manage their water use more rationally, potentially reducing average consumption by around 5 %. Additionally, heterogeneity analysis reveals that the installation of smart water meters and mobile apps led to increased water use among households with low baseline consumption and decreased water use among those with high baseline consumption. The empirical findings provide key insights for smart metering implementation and offers practical recommendations for policymakers.

期刊介绍： The Journal of Behavioral and Experimental Economics (formerly the Journal of Socio-Economics) welcomes submissions that deal with various economic topics but also involve issues that are related to other social sciences, especially psychology, or use experimental methods of inquiry. Thus, contributions in behavioral economics, experimental economics, economic psychology, and judgment and decision making are especially welcome. The journal is open to different research methodologies, as long as they are relevant to the topic and employed rigorously. Possible methodologies include, for example, experiments, surveys, empirical work, theoretical models, meta-analyses, case studies, and simulation-based analyses. Literature reviews that integrate findings from many studies are also welcome, but they should synthesize the literature in a useful manner and provide substantial contribution beyond what the reader could get by simply reading the abstracts of the cited papers. In empirical work, it is important that the results are not only statistically significant but also economically significant. A high contribution-to-length ratio is expected from published articles and therefore papers should not be unnecessarily long, and short articles are welcome. Articles should be written in a manner that is intelligible to our generalist readership. Book reviews are generally solicited but occasionally unsolicited reviews will also be published.
