Study On China's Energy-Saving Technology Importation From Japan And Its Effects

In the 21th century, energy crises have become more and more crucial in international economy as well as social development. Therefore, facing energies and resources that are increasingly scarce, energy-saving and reduction of consumption turn to be a key way to sustainable development, and an important strategic measure of taking a leading economic position in the future. Japan takes the lead in energy-saving and reduction of consumption, which has been accumulating relevant cutting-edge technologies as well as valuable experience. Meanwhile, China has become the second largest energy-consuming country in the world, which already displayed disparities from developed countries with its low efficiency of energy usage. As a consequence, China's importation of energy-saving technologies and experience from Japan plays an increasingly important role in advancing its level of energy-saving as well as realizing sustainable development of an economic society.Firmly based on statistics and analyses on industries such as chemistry, steel, cement and general devices, this paper first builds up an input-output model, via analyzing the input-output chart between China and Japan as well as relevant data. Then, by calculating the consumption coefficient of needs per unit between the two countries, the paper investigates and analyses the actual energy-saving effects after China's importation of Japanese technologies. There are three results in brief.1) Coal consumption plays the main role in China, meanwhile some diversities on energy input show themselves in Japan, which consequently turn out to be more efficient than its counterpart.2) By means of technology transfer, China shows great potential in energy saving, which suggests itself by optimizing the energy-consuming structure and reducing energetic consumption.3) Compared with those of China's, the Japanese industries which are the most effective in energy saving turn out to be industries of general devices, steel and cement, etc.The paper represents three points of innovation.1) Innovation in research methods. This paper makes qualitative analyses of China's energy-saving effects after the technological importation by means of input-output model, and thus can be believed to draw a conclusion which is more accurate and comprehensive. Thus, the analyses may provide guidance for researches on economic cooperation between China and Japan.2) Creativities of analytical methods used. The paper employs coefficient of input to indicate variations of energy usage, reflecting different levels of energy consumption under various technological conditions.3) Precise direction of research conclusions. The paper places emphases on compatibility as well as feasibility of technological transfer, which undoubtedly will show great significance in cooperations in both energy-saving and environmental protection between the two countries.
