Research On The Embodied Energy Measurement In China Import And Export Trade

International import and export business scope is being expanded with the continuous development of world economy. In recent years, a rapid growth trend is happening on China’s energy demand and greenhouse gas emissions."China Energy Threat Theory" has appeared in different version. A deep interpretation of "Embodied Energy" is needed. To calculate embodied energy of China’s import and export trade using input and output model will help confirm that China is the country of energy consumption from the perspective of consumer side, but not the final consumer of energy products.In this thesis, the author start from embodied energy and integrate five categories’ difference, which are embodied energy’s measurement area, data source and classification, model application, error sources, the embodied energy structure and energy security evaluation. The innovation point of this article is imitating the input and output model, using China’s input-output table which are provided by WIOD and the total energy consumption data from year1995to2009, dividing the China’s all departments in accordance with the international standard WIOD into34departments which excluding household consumption, and calculating34departments’ unilateral trade import and export energy value of China. Then, using total energy consumption of China, Japan, the U.S., Australia, Korean and Germany from year1995to2013. The author calculates the upper limit value of embodied energy in China import and export trade. As the technical level in Japan is in the leading position in the world, the author make an assumption and calculate the lower limit value of embodied energy in China import and export trade by replacing the Chinese direct consumption coefficient and energy consumption intensity into Japanese’s. And also calculate the average net value of embodied energy by using the six countries’ value. In this thesis, the author introduces import and export coefficient to modify the model and it help with reducing the error in measuring.The result shows that, after contrasting the measurement of China’s import and export of energy intensity by department from year1995to2009and the energy intensity of whole country from year1995to2013, the author finds China’s overall energy intensity are4-13times much higher than countries like Japan and the U.S. And also, the author finds most of the embodied energy consumption are happened in China’s primary energy department. The top three departments of energy consumption value in Chinese unilateral trade in2009are electric, gas and water supply industry, refined oil and fuel industry, and basic metal and metal industry. Those three high level energy consumption departments’ value is of44.11%among Chinese overall34departments’ energy consumption value. The author also finds that there is a huge gap between the upper limit and lower limit of China’s import and export embodied energy when calculating the interval net value. Influenced by low direct consumption coefficient and the influence of the energy intensity of the U.S, Japan, Australia, Germany and South Korea, the average net value of China’s import and export trade embodied energy lays in a low level and with slow growth trend, which of the result should belong to the reasonable scope. It is proved that China is the country of net-exporting embodied energy. Finally, this thesis show propose some relevant measures and policy suggestions, which encouraging the exploitation and utilization of new energy, and come up with some improving strategies from different perspective like the governor and citizen.
