Using the data of 40 host countries during 2010 to 2017, we investigate whether the Belt and Road Initiative (BRI) has brought new opportunities to countries along the routes to participate in global value chains (GVCs). We employ a difference-in-differences (DID) method with propensity score matching (PSM) to solve the self-selection bias problem. The results indicate that BRI has a significant positive effect on promoting the countries along the routes to participate in GVCs, and the effect is lagging and fluctuant. Specifically, we find that the promotion effects are particularly significant in the second year of the BRI’s implementation. The heterogeneity analysis of Belt and Road (BR) countries shows that there remains a significant positive effect on developing BR countries as before, while the opposite is true for developed BR countries.

Using the panel vector autoregressive (PVAR) model accompanied by the system-generalized method of moment (System-GMM) approach, this paper investigates the dynamic causality between participation in global value chains (GVCs), renewable energy consumption and carbon dioxide (CO2) emissions throughout 1990–2015 for 172 countries. The results show that participation in GVCs negatively causes renewable energy consumption except for the Middle East and North America (MENA) and sub-Saharan Africa. Second, except for the Asia–Pacific region and globally, participation in GVCs has no causal impact on CO2 emissions, and participation in GVCs has a positive effect on CO2 emissions in the Asia–Pacific region and globally. Third, except for globally and sub-Saharan Africa, CO2 emissions have no causal impact on participation in GVCs; however, CO2 emissions hurt participation in GVCs globally and in the sub-Saharan African region. Forth, renewable energy consumption positively causes participation in GVCs in MENA, while renewable energy consumption does not cause participation in GVCs globally and in other regions. Fifth, there is no causality between CO2 emissions and renewable energy consumption both at the global and regional levels. Several policy implications are proposed and discussed for promoting participation in GVCs and improving the environment.
