Drivers of Trade in Clean Energy Technologies: Evidence from a Gravity Modeling Approach

With the necessity of a transition toward the production and usage of green energy comes the need for clean energy technologies (CET). We develop a gravity model to analyze the determinants of trade flows for individual technical components of CET. For 58 component–technology combinations and 64 countries, a two-stage panel regression approach is applied. It yields estimators for bilateral regressors as well as regressors determining importer and exporter fixed effects, thus indicating which variables influence push and pull factors of trade in CET. Our analysis reveals that GDP and infrastructure determine a country’s competitiveness in terms of its ability to export components of CET to foreign markets, as well as the attractiveness of the country’s domestic market, which describes its ability to acquire goods from other countries. We also find that prices have a positive impact on export activities while the impact of energy intensity is negative. Economies with a higher share of research and development-intensive industry also tend to perform better in world trade of CET.
