国际垂直专业化、贸易分工模式与福利

在标准贸易理论框架下，通过引入垂直专业化和片段化生产，从理论上分析了国际垂直专业化对各参与国贸易分工模式的拓展及对国民和要素所有者福利的影响。研究结果表明，垂直专业化使一国比较优势由产品间深入到产品内部，进而使得各参与国贸易分工模式更为复杂，一国贸易模式可能会与该国原有的传统比较优势相悖；垂直专业化增进了世界福利，但在特定分工模式下可能会损害一国的福利，并且对于不同要素所有者福利的影响是不确定的。

Vertical Specialization, Patterns of Specialization and Trade and Welfare Effects

Under the standard trade models,this paper examines the effects of vertical specialization on patterns of specialization and trade,on national welfare and on factor prices.Results are as follows: vertical specialization makes the comparative advantage deep into intra-product,and makes the patterns of specialization and trade complex.The patterns of specialization and trade may be inconsistent with one country's original comparative advantage.Vertical specialization increases world welfare,and may hurt one country's welfare by turning its terms of trade against it.The effects on relative factor prices are uncertain.In the end,the authors put forward the inspiration of vertical specialization to China.
