Study on the relationship between the energy consumption and economic system of Jiangsu Province base on grey relational analysis

This paper applies the grey relational analysis to measure the grey relational degree between the energy consumption and the economic system from 2000 to 2007. The results show that the fixed asset investment of the economic system is the major factor which results in a rapid growth of the energy consumption; the grey relational degree between coal consumption and economic system is greater than the degree between the crude oil or natural gas and economic system, and it indicates that the economic development of Jiangsu province is still in an extensive growth mode; the grey relation between natural gas consumption and economic system is smaller, however, it is an important guarantee for the rapidly economic growth of Jiangsu province.
