This study utilises structural gravity models to examine the impact of globalisation on distance in agricultural and processed food trade, the relative effects of international distance and home bias effects. The results show that larger internal distances lower domestic sales. The home bias effect is substantially larger in agricultural commodities compared to processed agricultural commodities. Omitted variable bias is observed in friction variables when the relative intra-national distance and home market bias are excluded. After controlling for relative intra-national trade costs and the home bias effect, globalisation does not lead to a smaller impact of distance on trade. Substantial heterogeneity exists when analysing individual commodities.

全球化与农产品贸易

本研究利用结构引力模型来研究全球化对农业和加工食品贸易距离的影响、国际距离和本土偏见效应的相对影响。结果表明，内部距离越大，国内销量越低。与加工农产品相比，农产品的本土偏见效应要大得多。当排除相对国内距离和国内市场偏差时，在摩擦变量中观察到遗漏变量偏差。在控制了相对国内贸易成本和本土偏见效应后，全球化并没有导致距离对贸易的影响变小。分析个别商品时存在很大的异质性。
