摘　　要：在对外开放过程中，我国各地区获取国际贸易利益的差异是解释我国区域经济不平衡的重要原因。本文从新新贸易理论出发，在厂商生产率异质条件下构建了我国省级国际贸易利益决定的分析框架，提出决定我国省级国际贸易利益的主要因素包括地区内部贸易比重、市场进入成本、劳动要素供给和厂商固定运营成本。地区内部贸易比重和市场进入成本越低，劳动要素供给越多，该地区获取国际贸易利益就越多；但是厂商固定运营成本对该地区国际贸易利益的影响有双重性，取决于“生产率效应”和“挤出效应”的比较。本文还运用2001—2010年的我国省级面板数据发现，无论是总体样本回归还是分东、中、西部的样本回归，地区内部贸易比重、市场进入成本、劳动要素供给均对国际贸易利益存在符合理论预期的显著影响；同时厂商固定运营成本对我国省级层面上国际贸易利益存在正向影响，这表明生产率效应超过挤出效应。The difference of international trade gain during the process of opening up is an important reason for the regional economic inequity in China. Based on the new-new trade theory,the paper developes a framework to analyze the determinants of Chinese international trade gain in the provincial level under the condition of firm's heterogeneous productivity,and concludes the determinants include the share of intra-region trade,the entry cost,labor supply and the fixed operation cost. The lower the share of intra-region and the entry cost,and the more labor supply,the greater the international trade gain. But the influence of the fixed operation cost on the international trade gain is not explicit,which depends on the 'productivity effect'and 'crowding-out effect'. Using China's provincial panel data from 2001 to 2010,this paper finds the significant effects of the share of intra-region trade,the entry cost and labor supply on the international trade gain in the overall sample regression,as in the sample regression of the eastern,central and western region,which comply with the theory. And the fixed operation cost has a significant positive impact on the international trade gain,which means that the'productivity effect'exceeds the'crowding-out effect'.
