The digital economy is considered important to achieve carbon peaking and carbon neutrality. This paper explores the impact of the digital economy on carbon emissions and renewable energy development using panel data for 67 countries from 2005-2019. The results show that there is an inverted U-shaped relationship between the digital economy and carbon emissions, which is consistent with the Environmental Kuznets Curve (EKC) hypothesis, and a U-shaped relationship with renewable energy consumption, which is consistent with the Renewable energy Kuznets Curve (RKC) hypothesis. Compared with gross domestic product (GDP), the digital economy is more likely to accelerate the process of energy transition and carbon reduction, which is a key factor for carbon peaking. In addition, it is also found that the turning point of the RKC precedes the EKC, which means that the RKC reaching its turning point is a prerequisite for the corresponding EKC to reach its peak.Therefore, the digital economy should be accelerated to push RKC to cross the turning point as soon as possible, thereby accelerating EKC to cross the turning point.
数字经济对于实现碳达峰和碳中和至关重要。本文利用 2005-2019 年 67 个国家的面板数据，探讨了数字经济对碳排放和可再生能源发展的影响。结果表明，数字经济与碳排放之间存在着倒“U”型关系，符合环境库兹涅茨曲线（EKC）假说，与可再生能源消费之间存在着“U”型关系，符合可再生能源库兹涅茨曲线（RKC）假说。与国内生产总值（GDP）相比，数字经济更有可能加速能源转型和碳减排进程，是实现碳达峰的关键因素。此外，还发现 RKC 的转折点先于 EKC，这意味着 RKC 达到转折点是相应的 EKC 达到峰值的前提。因此，应加快数字经济发展，推动 RKC 尽快越过转折点，从而加速 EKC 越过转折点。
