آیا صرفه جویی در انرژی باعث رشد اقتصادی می شود؟ شواهد از یک مجموعه داده های پانل چند کشور و چند بخشه

We examine the causal relationship between energy efficiency and economic growth based on panel data for 56 high- and middle-income economies from 1978 to 2012. Using a panel vector autoregression approach, we find evidence of a long-run Granger causality from economic growth to lower energy intensity for all economies. We also find evidence of long-run bidirectional causality between lower energy intensity and higher economic growth for middle-income economies. This finding suggests that beyond climate benefits, middle-income economies may also earn an extra growth dividend from energy efficiency measures.
