Firms, markets and trade costs: access of French exporters to European agri-food markets
基于法国出口商数据，研究欧洲农产品市场碎片化程度，发现企业需达到一定生产率门槛才能进入，且市场差异源于地理条件和贸易成本。
From the French exporters' point of view, the purpose of this article is to understand the extent by which the European (EU) market remains fragmented. Based on Chaney's model (Chaney, 2008) it is shown here that to enter the market, the firm's productivity must be higher than the productivity threshold. Using accounting and trade firm data for the year 2004, the value of the threshold at entry to each EU country is explained and then the value exported to each market. The results of this study reveal that the heterogeneity of EU markets is due to geographic conditions, as also the remaining trade costs at entry to these markets.
