Globalisation and agri-food trade
利用结构引力模型研究全球化对农产品和加工食品贸易中距离效应的影响，发现国内距离降低国内销售，且农产品本土偏好效应强于加工品，控制相关变量后全球化并未缩小距离对贸易的影响。
Abstract 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.
