Abstract: Economic policy uncertainty is an important factor influencing the export of enterprises. Based on the micro-data of Chinese industrial enterprises and through constructing an empirical model, this paper tries to analysis the impact of economic policy uncertainty on the export willingness and export volumes of enterprises. The results show that the economic policy uncertainty will affect firm export behavior significantly. To be specific, the increasing domestic economic policy uncertainty would promote the export willingness and export volumes of enterprises; while the increasing economic policy uncertainty in destination countries would inhibit both the export willingness and volumes of the domestic enterprises. The basic conclusion of this paper is still valid after tests under various conditions are considered. The study of this paper not only extends the empirical analysis of firm heterogeneity trade theory, but also deepens our understanding of the economic effects caused by the economic policies.

Key words: economic policy uncertainty; firm export participation; firm export volume
