It is becoming more and more important to identify the correlation between electricity consumption and economic growth with the continuing electrification in China. It is constructed the Panel vector utoregression model and the impulse response function to identify economic growth, electricity consumption and structural change in China based on a provincial level panel data,in order to compare the difference of the correlation between the national level and Jiangsu province. There is a stable correlation between electricity and economic characteristics both nationwide and in Jiangsu. The national economic growth has a greater influence on electricity consumption in the short term and a weaker one in the long term, while there is a more consistent impact of economic growth and structural change on electricity consumption in Jiangsu,which reflects a more coordinated interaction between the electricity market and the economy and structure in Jiangsu. The difference of the correlation suggests that policy makers ought to make electricity investment plans according to the regional economic development level.
