【摘要】 基于不完全竞争、规模经济和H-O贸易理论,建立了一个分析框架,从同质产品行业和差异化产品行业两个角度,分别推导了行业贸易引力方程.结果表明,在行业贸易引力方程中,要用行业GDP来表示行业出口供给能力,而不是用国家整体GDP来表示,一国某一行业的出口量一定程度上取决于行业GDP,而不是一国的GDP.更多还原

【Abstract】 This paper established an analytical frame from imperfect competition,scale economics and H-O trade theory,and derived a gravity equation from homogeneous products and differentiated products.The result indicates,in the industrial gravity equation,it is by the industry GDP to represent the industry export supply ability,but not by the whole GDP. One country’s industrial export volume is in proportion to the industrial GDP, not the whole GDP.更多还原
