The relationships among energy consumption, economic output and energy intensity of countries at different stage of development

摘要: Based on 3GR model, the relationships between energy consumption, economic effect and technical of countries at different stage development (developed, developing least developed countries) was figured out. Comparing equivalent value GREC, GREO GREI during period from 1996 to 2013, diverse laws in kinds found. The following conclusions were obtained: (1) based there is a liner relationship GREC or an inverse when (1+GREOi) (1+GREIi) (1+GRECi) constant. (2) are orders, < countries, while that have opposite orders. orders small large. own largest potential realize further whether expansion, innovation optimize industrial structure these smallest middle level; shows most growth going forward. (3) change consumption codetermined by EO effect, EI their interactive effect. leading position among three effects, especially countries. In EC change, both tight range. While ranges rather
