The decision to export: Firm heterogeneity, sunk costs, and spatial concentration

Integrating perspectives of the Uppsala model of internationalization process, international new ventures and trade theories of heterogeneous firms, this paper develops a dynamic discrete-choice model of export decisions by a profit-maximizing firm. Empirical analyses based on a panel data set of Chinese firms show that sunk costs, productivity, firm size, foreign ownership, industry competition and spatial concentration are positively associated with the decision to export, while state ownership has a negative association with the probability of exporting. However, we find that the relationships are not always uniform and depend on firm-specific idiosyncrasies. The results show that foreign-invested firms and large firms (regardless of ownership) rely on productivity performance related advantages for expanding overseas, while domestic firms, especially small- and medium-sized enterprises, build competitive advantage by leveraging agglomeration economies and the associated spillovers. Our results highlight the role of firm heterogeneity, sunk costs and spatial concentration in shaping the export behavior of firms.

► We integrate the Uppsala model, international new ventures and trade theories.
► Firm heterogeneity and sunk costs significantly influence the export decision.
► Industry competition and spatial concentration are also important.
► The relationships are not always uniform and depend on firm-specific idiosyncrasies.
