Quantitative Analysis on the Temporal and Spatial Differences of the Energy Production and Consumption in China in the Last 30 Years
1978 年以来中国能源生产与消费时空差异特征

Based on the energy and economy data from 1978 to 2005, this paper measures the variation track of energy production and the consumption gravity center in China, and analyses the relations between the energy production and consumption and the economic development. The results are as follows: 1) The variation track of the energy production gravity center is moving to southwest by step, the gravity center moved to west by 3.29o and by 1.18o to south, this shows that the disparities of energy production between south and north is decreasing, the disparities of energy production between west and east is decreasing too, the decreasing rate of the latter is larger than the former one. 2) The variation track of energy consumption gravity center is moving to southwest by step, and the fluctuation of the track is more distinct, during 1998 to 2002, the movement of gravity center is not obvious, this shows that the increasing rate of energy consumption of each province is similar. 3) The variation track of GDP gravity center is moving to both longitude and latitude direction. 4) Although there are some similar characteristics between energy production and consumption gravity center, the difference between them is significant too. Based on comparative analysis of the energy and GDP gravity center, we can find that there are intimate relations between economic development and energy consumption.
