根据迈克尔·波特的有关论述 ,一国之所以强盛 ,根本原因在于该国有一个驰骋于世界的产业群。本文从制造业和服务业入手 ,揭示了当代日本的竞争优势。分析结果表明 ,虽然日本近几年经济不景气 ,但其优势产业的格局基本上没有太大的变化。日本的竞争优势典型地说明 ,当今一国经济发展中后天形成的竞争优势的作用越来越大于天然禀赋的比较优势 ,同时也表明支撑发达国家强盛的国家竞争优势有着许多的共性。 According to the relevant exposition of Michael Porter, the reason why a country is so powerful is that the country has an industry group that is flying in the world. Starting with the manufacturing and service industries, this article reveals the competitive advantages of contemporary Japan. The analysis shows that although Japan has experienced a sluggish economy in recent years, the pattern of its dominant industries has basically not changed much. Japan’s competitive advantages typically illustrate that the role played by today’s competitive advantages in the economic development of a country is increasingly greater than the comparative advantage of natural endowments and also shows that there are many commonalities in supporting the strong national competitive advantage of developed countries.
