China's Export Trade Implied Energy Research

Since China's entry into WTO, foreign trade has been on the rise continuously, but the domestic consumption of energy has been surging at the same time. With the deepening of the conflict between domestic supply and demand, energy issue has become the bottleneck of China's economic development. It is of great theoretical and practical significance to study the embodied energy consumption in trades. That is because in the production of China's export goods there are not only direct consumption of energy on the production line, but also indirectly consumption through intermediate-input.In this paper, statics concerning industrial energy consumption, GDP, and total export volumes are employed, through input-output method, to predict the full energy input-output coefficient and embodied energy consumption of export goods in various industries across China. The results show that China's full energy input-output coefficient is decreasing year by year, whereas energy efficiency is on the increase. China's embodied energy consumption of export goods is also climbing up annually, a large proportion of which are energy-intensive products. And the massive export of non-energy-intensive goods drives the export of China's embodied energy consumption.After that, parameters that affect changes of China's embodied energy consumption of export goods are analyzed with Log-mean Divisia Index Method. The results demonstrate that the changes are mainly subject to the effects of scale and techniques, and relatively little to the structure effect. To be specific, as the scale of export expands, the export of embodied energy is accordingly increasing, and as the efficiency of energy consuming improves, the export of embodied energy is to decrease, and the negative structural effect turns to a positive one after 2002. Last but not least, suggestions pertinent to reducing the export of embodied energy are put forward based on the results above.
