As the investment in renewable energy power generation capacity exceeds 300 billion dollars per year, the performance of these capacity investments becomes more and more noticeable. This paper empirically examines the impact of import on the technical efficiency of electricity generation capacity investment by using panel data from 14 countries during the period between 2004 and 2019. The findings demonstrate that the technical efficiency of capacity investment varies from 23 percent to 88 percent, and it is increasing over time. Secondly, the import of renewable energy related commodities has a significantly positive impact on inefficiency reduction.
