摘　　要：本文基于世界投入产出数据库,考察了供应分散度和贸易品同质性对贸易距离弹性的影响。研究结果表明:当供应来源地越分散时,地理距离对贸易的阻碍作用越强,即就近购买更可能发生;相比最终品贸易,这一现象在中间品贸易中表现得更为显著,而中间品本身更强的同质性可能是产生上述差异的原因。Based on the world input-output database, this paper explored the effects of supply dispersion and tradable goods homogeneity on trade-distance elasticity. Empirical results show that:(1) when the source of supply is more dispersed, the geographical distance has a stronger negative effect on trade, i.e., nearby procurement is more likely to happen.(2) In comparison with trade in final goods, this phenomenon is more pronounced in terms of trade in intermediate goods. The higher homogeneity of intermediate goods might be the reason behind above phenomenon.
