Analysis on contributions of energy consumption to economic growth for Harbin as an example

From the micro analysis aspect, energy consumption aggregate, energy consumption elasticity and energy consumption intensity of Harbin were quantitatively analyzed in the paper, Gross Domestic Product was regarded as the target, energy consumption aggregate of coal, crude oil, natural gas and electric power of industrial enterprises above designated size were made as the constraints, the model of multiple regression analysis was constructed to measure contributions of energy consumption to economic growth. The results have shown that the consumption of coal, oil, natural gas and electric power had a positive role on economic growth of Harbin, in which the coal was the maximum contribution, the oil was the second, and the electricity and natural gas were relatively small.
