The Comparative Analysis Of The Embodied Energy For China,German,US And Japan

Since the beginning of the twenty-first century,the climate of the global have happened the great changes.For examples,a series of problems of global warming,exhausting energy and environment degradation and so on.On the background,the world?s major trading powers conducted on the energy consumption and environmental pollution problem have caused the attention of the world,especially the voice from the developed countries,they accused that developing countries is the chief culprit for causing global warming and environment deterioration,and then presented “China?s energy threaten theories” and “China?s climate threaten theories” and so on.Since reform and opening up,it is true that China has realized rapid economic growth.At the same time also brought a series of energy shortage,environment pollution and so on.But global warming is not caused by China alone.China has been committed to the implementation of energy conservation and emissions reduction work,.For example,China has completed the 12 th five-year plan for the proposed objectives such as saving energy and reducing consumption,improved the efficiency of resource using.And announced that “China?s CO2 mission per GDP in 2030 will decrease 60% to 65% in 2005” Reducing the energy consumption intensity,realizing the economic green,harmonious and sustainable development has risen to the height of the national level,it has caused the great importance to China.Because of this background,this paper has conducted the contrast study for the energy consumption for the world's leading trading power,mainly adopted the input-output model,measured the energy consumption data for the China,German,United States and Japan of the export trading.Meanwhile,adopted the LMDI factor decomposition method analysis the energy consumption in export trading,and compared with the scale of the change,structural change and intensity change for the world major trading countries.Through the study found the following conclusions: Firstly,in the 2014,the energy of consumption in the world major trading countries for example China,German,United States and Japan have increased than 2001.Energy conservation and emission reduction remains the theme of the every country.But,China's energy consumption is 9.19 times compared with Japan and 6.22 times compared with Germany and 2.3 times compared with United States,China's energy saving is a long road.Secondly,Compared 2001 and 2014,we concluded that China,German,United States and Japan of the energy conservation and emission reduction have decreased.Thirdly the scale effect and structure scale effect have increased such as Coke,Refined Petroleum and Nuclear Fuel,Electrical and Optical Equipment.It is not disadvantage to the realization of energy conservation and emission reduction.But the decreasing of the effect of intensity is advantage of the total energy consumption decreasing in the export trading.
