Abstract: Because of the weak recovery of global economy, slow development of European market and American market, the decline of major international commodity prices, the appreciation of RMB and other factors, foreign trade has gone into a serious situation and we need to explore a new mechanism of trade growth. Trade facilitation will reduce trade costs and promote bilateral trade. Direct investment towards foreign countries has an important influence on export. However, there is few people studying on whether the export of direct investment towards foreign countries is effected by trade facilitation. In order to analyze trade facilitation, the effect of direct investment towards foreign countries on export and whether the export of direct investment towards foreign countries is effected by trade facilitation, this essay constructs trade facilitation Index system, measure trade facilitation level of 123 countries(regions included)of the world from 2009 to 2015 with principal components analytic method, construct the stochastic frontier gravity model combined with GDP, population, spatial distance, direct investment towards foreign countries and export data. In order to analyze whether the export of direct investment towards foreign countries is effected by trade facilitation, this essay will split the samples into higher group and lower group according to the level of trade facilitation and analyze again separately. According to researches, first of all, trade facilitation and direct investment towards foreign countries greatly motivates Chinese export. Every 1% increase of the former will give 0.212%、0.56% increase of the latter. Second, the increase of trade facilitation level will remarkably stimulate the export of direct investment towards foreign countries. Their cross term coefficient reaches 0.23. In separately analysis, regions with high level of trade facilitation has a 0.37 high level of cross term coefficient, which is much higher than 0.06 of regions with low level of trade facilitation. Therefore, speaking of direct investment towards foreign countries, the investment towards regions with high level of trade facilitation needs to be reinforced to stimulate export.

Key words: trade facilitation, OFDI, export effect
