An Analysis of Influential Factors of Energy Efficiency Based on Grey Relational Grade
〔Abstract〕 Due to the increasingly serious energy shortages and environmental pollution , there are higher demands for reducing ener-gy intensity . At first , the paper is committed to presenting an analysis of the function mechanism which the industrial structure , the level of urbanization , the structure of energy consumption , the energy conversion efficiency , energy prices and the structure of foreign trade have on energy intensity and using econometric software Eviews to test the causal relationship at the same time . Both mechanism analysis and test results show that the industrial structure , the level of urbanization , the structure of energy consumption , the energy conversion ef-ficiency , energy prices and the structure of foreign trade are influential factors of energy intensity . And then the author establishes a model for influential factors of energy intensity based on grey relational grade , arriving at the conclusion that among the six factors , according to the degree of correlation with energy intensity , from high to low are successively energy prices , industrial structure , energy consumption structure , energy conversion efficiency , urbanization level and foreign trade structure . On the basis of the results of the model , this paper puts forward a proposal of setting reasonable prices of energy and accelerating the transformation of industrial structure .
