【摘要】 通过建立三个不同专业化程度的贸易量模型分析专业化程度与贸易量之间的基本变动关系 ,表明两国之间的贸易量不仅与国家相对规模成正比 ,而且专业化程度越高 ,贸易量越大。扩展后的模型研究发现 ,一国某一典型产品的出口贸易量不仅取决于本国收入 ,而且还取决于该产品国内产值占本国收入比例与该产品世界产值占世界收入比例的差别 ,差别越大贸易量越大 ,而这种差别可看作是产品专业化生产程度的反映。更多还原

【Abstract】 Establishing three models each with different trade volumes and specialization degrees and analyses the relations between specialization and volume of trade. It is founded that the volume of trade between two countries is in proportion to relative scales of each nation, and the higher extent of specialization, the greater the volume of trade is. Expanded model shows that the export volume of a certain typical product in one country is not only decided by national income but also decided by the difference between the ratio of the production of a national revenue and that of the world. The difference can also be regarded as a reflection of the extent of specialization, that is to say the higher the extent of specialization, the more the volume of trade.更多还原
