In France, the vast majority of exporting enterprises are SMEs, although they are responsible for only a small proportion of total export. In 2013, 20% of SMEs in manufacturing industry and wholesale trade were exporters; they were often larger and more productive than other SMEs. Export activity in terms of turnover is strongly concentrated in these enterprises. SMEs with a low export intensity sell their products more intermittently than those with a high export intensity, which are a more permanent feature on the market. The company’s own cash resources can account in part for these differences. Exporting SMEs do have more financing needs, especially in the short term, in order to cope with long payment deadlines in international transactions. A study of the effects of the provisions of the 2008 Economic Modernisation Act (Loi de modernisation de l’économie) to reduce payment deadlines suggests that enterprises that experience the longest delays probably have the most fragile export dynamics. These effects remain modest mainly as a result of the impact of the 2008 financial crisis.
