中文摘要：

文章使用43个国家1980～2011年的跨国面板数据对影响外贸依存度的因素进行国际比较、实证估计与拓展分析，结论表明：（1）人口、城市化率、FDI占比、居民消费率和实际有效汇率显著影响世界各国的外贸依存度，且外贸依存度具有较强的惯性；（2）将私人信贷占比作为金融发展的代理变量与净外国资产占比变量分别引入基准方程进行实证研究，没有找到金融发展与净外国资产占比显著影响外贸依存度的证据。

英文摘要：

In this paper, we analyze and compare the determinants of foreign trade dependence ratiousing the panel data for 43 countries from 1980 to 2011. We find that population, urbanization, FDI ratio, household consumption ratio and real effective exchange rate have significant effects on the foreign trade dependence ratio and the foreign trade dependence ratio has a strong inertia. Then we add the ratio of domestic credit to private sector to GDP as the proxy variable of financial development into the benchmark model, but we have not found significant results supporting the evidence that financial development has any relationship with foreign trade dependence ratio. At the same time, we add the ratio of net foreign assets to GDP into the benchmark model, but we have not found significant results supporting the evidence that the ratio of net foreign assets to GDP has any relationship with foreign trade dependence ratio.
