This paper aims to investigate the effects of information and communication technologies (ICT) on carbon emissions (CO) in the OECD area. For this purpose, a comprehensive panel data set is utilized covering the 1994-2018 period for 38 countries and a novel method of moments panel quantile regression model which allows to account for fixed effects and endogenous explanatory variables. Results suggest that the ICT, represented by the percentage of individuals using the Internet in the total population, contributes positively to CO emissions up to 0.40th quantile and has no effect after this level. The results imply that countries with relatively low per capita emissions are susceptible to the rebound effects, in which better energy efficiency results in increased demand for energy and ICT-related items, hence increasing carbon emissions. At this juncture, one policy idea would be to include a carbon tax into the per-unit purchase price of smartphones, tablets, smart gadgets, and any other relevant ICT items. Additionally, this legislation can assist decrease conspicuous consumption, which can be viewed as a trigger for the demand for ICT products. Additionally, these countries should encourage enterprises to invest in and employ energy-efficient technologies through tax incentives or subsidies.
本文旨在研究信息和通信技术（ICT）对经合组织地区碳排放（CO）的影响。为此，利用了一个涵盖 1994-2018 年期间 38 个国家的综合面板数据集，并采用了一种新的矩面板分位数回归模型方法，该方法允许考虑固定效应和内生解释变量。结果表明，以互联网在总人口中所占比例表示的 ICT 在 0.40 分位数之前对 CO 排放有积极贡献，而在此水平之后则没有影响。结果表明，人均排放量相对较低的国家容易受到回弹效应的影响，在这种效应中，更好的能源效率导致对能源和与 ICT 相关物品的需求增加，从而增加了碳排放。在这一时刻，一个政策思路是将碳税纳入智能手机、平板电脑、智能小工具和任何其他相关 ICT 物品的单位购买价格中。此外，这项立法可以帮助减少炫耀性消费，这可以被视为对 ICT 产品需求的触发因素。此外，这些国家应通过税收激励或补贴鼓励企业投资和采用节能技术。
