Using panel data from BRICS countries over the period 2000 to 2018, a multi-variate threshold model was built to investigate how global value chain (GVC) participation and information globalization affects CO emission. We further decompose the information globalization into two indicators, i.e., de facto measure and de jure measure. The main findings show that the estimated value of threshold is 4.02 and 1.81 for both de facto and de jur measures of information globalization. The findings suggest that information globalization rate above the threshold level negatively affects the carbon emissions. De facto and de jure measures show a strong single threshold effect when GVC participation is chosen as the major explanatory variable. Similarly, participation in GVCs has a large single threshold impact when information globalization is taken as the primary independent variable. Overall, the results show that the larger the information globalization for the countries under analysis, the modified impact of GVC participation on CO emission reduction is larger. The robustness test validates the stability and coherence of the study's findings. The opportunities that the information globalization along the approach to participate in GVCs presents for the accomplishment of carbon neutrality should be properly utilized by policymakers. There should be expansion the participation in GVCs with digital infrastructure and to enhance the assessment system for the use of technology spillover effects to increase environmental-friendly GVC ladder.
利用金砖国家 2000 年至 2018 年的面板数据，构建了一个多变量门槛模型，以研究全球价值链（GVC）参与度和信息全球化如何影响 CO 排放。我们进一步将信息全球化分解为两个指标，即事实上的措施和法律上的措施。主要发现表明，信息全球化的实际措施和法律措施的门槛值估计值分别为 4.02 和 1.81。研究结果表明，信息全球化率超过门槛水平会对碳排放产生负面影响。当选择 GVC 参与度作为主要解释变量时，事实上的措施和法律措施均显示出较强的单一门槛效应。同样，当信息全球化作为主要自变量时，参与 GVC 对减排的影响也具有较大的单一门槛效应。总体而言，结果表明，参与分析的国家的信息全球化程度越大，GVC 参与对减排的修正影响就越大。稳健性测试验证了研究结果的稳定性和一致性。决策者应充分利用信息全球化参与 GVC 带来的机遇，实现碳中和。应扩大数字基础设施参与 GVC，并加强技术溢出效应的评估体系，以提高有利于环境的 GVC 阶梯。
