摘　　要：国际贸易理论的发展可以分为二战前和二战后两个时期,二战前的国际贸易理论以比较优势为核心,二战后的新贸易理论以规模经济和竞争优势为核心。但是,至今国际贸易理论界没有一个比较全面的观点来整合以上两套理论系统。本文提出的相对效用价格比的概念及其分析框架,拓展了的比较优势概念,整合了要素生产率决定的比较成本优势与要素价格决定的比较成本优势,相对价格优势与非价格优势,完全竞争市场的比较优势与不完全竞争市场的比较优势,是一个综合以往国际贸易理论中贸易决定基础理论的现代观点的范式。We can part the seedtime of International Trade Theory into two periods, pre-war phase and post-war phase. Pre-war phase of International Trade Theory is featured by comparative advantage, while post-war phase is featured by scale economy and competitive advantage. Whereas, so far, there is no all-around theory which can integrate these two theoretical system ingeniously. In this paper, the concept and the analytical framework of relative utility price ratio we put forward extend the spirit of comparative advantage. At the same time, it integrates the relative price advantage determined by factor productivity and that determined by factor price. On the other hand, it integrates relative price advantage and non-price advantage, as well as comparative advantage in perfect competition market and that in imperfect competition market. Generally, the theoretical framework of relative utility price ratio is a modernistic paradigm that synthesizes the trade determinants of previous International Trade Theory.
