Does economic complexity increase energy intensity?

Abstract Today, many countries in the world pay special attention to energy efficiency improve environmental quality and reduce waste of resources. For this purpose, research has investigated economic complexity intensity (EI) from 1995 2019 using club convergence panel quantile regression (PQR) models. The results showed that out 62 countries, 42 converged during period. Then, PQR model, determining factors EI for these were evaluated: complexity, urbanization, trade openness, industrial production, foreign direct investment, oil price, growth. result model confirmed an inverted U-shaped relationship with EI. Urbanization investment have a positive increasing effect on In addition, openness positively affects EI, mainly 10th 25th quantiles. On other hand, growth decreasing Moreover, industrialization prices can particularly 90th quantile. Given intensity, where lower higher quantiles are negative, it is advised policymakers ought promote leap levels by reducing intermediate as much possible. Policymakers should also be conscious promoting diffusion mitigates noxious gas emissions.
