Trade Openness and Industrial Productivity

Abstract

This article examines how trade openness shapes industrial productivity by synthesizing theoretical, firm-level and cross-country research. It argues that openness raises productivity through several mutually reinforcing channels, including competitive pressure from imports, access to imported intermediate inputs and embodied technology, opportunities created by export markets, and the reallocation of resources from less efficient to more efficient producers within industries. These gains are neither automatic nor uniform. Their size depends on the absorptive capacity of domestic industries, the quality of institutions, the depth of human capital and infrastructure, and the flexibility of factor markets that allow resources to move. The discussion reviews evidence from Chile, Indonesia, India and multi-country studies, considers the measurement problems that complicate inference, and presents a stylised conceptual figure showing how the productivity response to openness varies across levels of absorptive capacity. The article concludes that openness is best regarded as an enabling condition rather than a guarantee, and that policy should combine liberalization of inputs with investment in capabilities, support for adjustment and continuous evaluation. It argues that openness works through identifiable channels, that the strength of each channel depends on the capabilities and institutions of the economy concerned, and that policy should therefore concentrate as much on the complementary conditions for absorbing the benefits of trade as on the level of tariffs itself. The method is a structured narrative synthesis of the theoretical and empirical literature, supported by a stylised conceptual figure that illustrates the argument.
