日本对华贸易的比较优势及其稳定性检验

The Comparative Advantage and Stability Inspection of Japan's Trade towards China

使用RCA指数和RRCA指数衡量日本对外贸易和对华贸易比较优势,结果显示日本在机械和运输设备及工业制成品等门类具有比较优势,而同时日本对华贸易比较优势稍强于日本对外贸易比较优势。通过计算贸易结合度和贸易互补度指标,我们认为中日两国贸易依存度较高。根据劳伦斯指数,我们发现日本1995年来对外贸易和对华贸易结构变动幅度较低,日本对外贸易具有一定的平稳度。具体到中国市场,日本对华贸易的比较优势呈稳健强化的趋势,具有显著比较优势的产品是日本对华比较优势最为稳健的一类产品。

This paper evaluated the competitive advantage of Japan＇ s trade outwards and to China by applying RCA and RRCA index which revealed that Japan had a comparative advantage in machinery and transport equipment and manufactured goods, and a more obvious advantage to China than to the world. We believed that Japan and China had a deep dependence of trade on each other by calculating the trade integration and complementary index. We still found that Japan had a stable trade structure with China since 1995. As to Chinese market, the comparative advantage of Japan-to-China trade took a grow- ing stable tendency and the products with the prominent advantage were those with the most stable com- parative advantage of Japan-to-China.
