In recent decades, the rapid development of the global society and economy has brought serious environmental problems, such as air pollution, greenhouse effect, and ecosystem degradation, all of which have attracted wide attention. Simultaneously, the use of Information Communication Technology (ICT) has been on the rise since the 1980s, which stimulates the growth of the economy and has a certain degree of impact on the ecological environment. Accordingly, the scientific community's interest in assessing this impact has grown considerably, and econometric methods are widely used as evaluation tools. However, the research results are often different in different regions, periods, environmental proxies, and ICT. Some studies indicate that the development of ICT is beneficial to environmental improvement, while others state that it is not. Therefore, a comprehensive analysis of the methods, mechanisms, and relative policy suggestions of this topic is desiderated. To address this gap, this paper carries out a systematic literature review of the usage of econometric methods in the assessment of the environmental impact of ICT. Among the 472 articles retrieved from scientific literature databases, 46 met the inclusion criteria and were analyzed in detail. This study aims to provide scholars with a mental picture of the current state of scientific research, identify the factors that influence the direction of ICT's impact on the environment, and enable future researchers to use more reliable and accurate estimation methods. The methods used in selected articles were divided into two main groups (i.e., time series models and panel data models), and panel data models were further subdivided into five categories. The detailed flow of these methods is summarized, and new advanced pre-test methods and estimators are highlighted. Furthermore, the analysis also indicates that among all the countries and regions involved in the selected articles, there is a non-strict inverted U-shaped curve between the level of socio-economic development and the direction of the impact of ICT on the environment. Finally, current research challenges are discussed, and potential directions for future research on this topic are also projected.

在最近几十年中，全球社会和经济的飞速发展带来了严重的环境问题，例如空气污染，温室效应和生态系统退化，所有这些都引起了广泛关注。同时，自1980年代以来，信息通信技术（ICT）的使用一直在增加，这刺激了经济的增长并对生态环境产生了一定程度的影响。因此，科学界对评估这种影响的兴趣大大增加，计量经济学方法被广泛用作评估工具。但是，不同地区，不同时期，不同环境的代表和ICT的研究结果通常是不同的。一些研究表明，ICT的发展有利于改善环境，而另一些研究则指出，这无济于事。因此，需要对本主题的方法，机制和相关政策建议进行全面分析。为了解决这一差距，本文对计量经济学方法在评估ICT环境影响方面的使用进行了系统的文献综述。从科学文献数据库检索到的472篇文章中，有46篇符合纳入标准，并进行了详细分析。这项研究旨在为学者们提供有关科学研究现状的心理印象，确定影响ICT对环境影响方向的因素，并使未来的研究人员能够使用更可靠，更准确的估算方法。所选文章中使用的方法分为两个主要组（即时间序列模型和面板数据模型），面板数据模型又细分为五类。总结了这些方法的详细流程，并重点介绍了新的高级预测试方法和估计器。此外，分析还表明，在所选文章涉及的所有国家和地区中，社会经济发展水平与ICT对环境的影响方向之间存在一条非严格的倒U形曲线。最后，讨论了当前的研究挑战，并展望了该主题未来研究的潜在方向。在社会经济发展水平与ICT对环境的影响方向之间存在一条非严格的倒U形曲线。最后，讨论了当前的研究挑战，并展望了该主题未来研究的潜在方向。在社会经济发展水平与ICT对环境的影响方向之间存在一条非严格的倒U形曲线。最后，讨论了当前的研究挑战，并展望了该主题未来研究的潜在方向。
