| Confronted with the double challenge of economic globalization in the fields of knowledge and technology, each country, no matter developed ones or developing ones, takes the export increase of mechanical and electrical products as one of the main productivity elements in realizing economic growth and also a strategic emphasis in developing export and launching technological and economic cooperation. As the relative landslide of Japan's mechanical and electrical industry development and China's mechanical and electrical industry goes on, the accelerating development of bilateral intra-industry trade of mechanical and electrical products between the two countries becomes the focus of attention, and to a great extent influences the two countries' industrial policies and economic relations.Based on intra-industry trade theory, the paper uses Aquino index to calculate and analyze the intra-industry trade condition of Sino-Japan mechanical and electrical products from 1992 to 2009, and through the comparison with Japan-US and Japan-EU, discovers that the overall intra-industry trade level of Sino-Japan mechanical and electrical products is very high, intra-industry trade has become the main pattern of Sino-Japan mechanical and electrical product trade. While through the calculation of mechanical and electrical products intra-industry trade structure, obtained that Sino-Japan bilateral intra-industry trade remains vetical intra-industry trade.On the basis of knowing the situation of Sino-Japan intra-industry trade, the paper makes empirical analysis on the influence factors of Sino-Japan mechanical and electronic products intra-industry trade, namely, to establish metrological model, select national income per capita, the level of opening, trade imbalance, foreign direct investment, technological progress and economies of scale these six factors to do regression analysis and examine each variant's influence to bilateral intra-industry trade of mechanical and electronic products. Finally, in view of China's low value-added exports of mechanical and electronic products, this paper puts forward some corresponding suggestions, foster strengths and circumvent weaknesses, to optimize the exports of mechanical and electrical products from China to Japan. |
