Abstract: Imbalance of energy’s production and consumption leads to energy’s large-scale flows in the space with the constantly changing flow patterns, which needs vertical and horizontal perspectives to analyze. This article constructed indicators to measure the direction and velocity of regional energy flows. Through multiple hierarchical clustering, 30 provinces (cities, districts) in the coal, crude oil and natural gas during 1995-2012 were divided into 7 flow function types, and input place, transit place and output place were mainly analyzed. Conclusions are as follows: Firstly, coal transport frequently between provinces in moderate size, which represents coastal input, steady output, and inland transit. Secondly, crude oil flow in large scale, which represents dispersed input, centralized output, and transit hub. Thirdly, natural gas is mainly self-sufficiency, which represents economic-circle, input multisource supply, and small-scale transit. Overall, distribution axis of energy consumption in China gradually closes to the Hu’s line, consistent with the trend of population.
