Taking Grubel and Lloyd to dance in the city: Domestic intra-industry trade in China
利用中国276个城市42个行业三年的大面板数据，检验了国内产业内贸易的决定因素，发现地理和技术距离是主要障碍，比要素禀赋差异更重要。
We assess theoretical predictions regarding the determinants of domestic intra-industry trade in large panel data of pairs of 276 cities, as well as pairs of 42 sectors, over three years in China. We find that geographical and technological distances are the main impediments of intra-industry trade, being more important than relative endowment differences. This confirms expectations based on new trade theory in a novel data environment.
