Focusing on the components of both solar photovoltaic technology and wind energy technology and using the gravity model approach with panel data, this study empirically investigated the determinants of bilateral trade in renewable energy goods among ASEAN countries as well as with China, Japan, and South Korea for the period 2012–2019, and also identified China’s export efficiency and export potential.

In general, it was found that China had great potential to export renewable energy goods. We propose that the ASEAN Plus Three region needs to formulate and implement a comprehensive and carefully coordinated renewable energy policy package. We also suggest that China should promote joint
