Industrial development, technological change, and long-run growth

To account for the qualitative differences between developed and developing countries, this paper argues that the expensive in-house R&D that manufact uring firms undertake in advanced industrial economies cannot be supported in countries that are in the early stage of industrialization and do not ha ve sufficiently large markets for manufacturing goods. Such economies grow as standard development models predict: by accumulating physical and human capital and increasing specialization by industry. Only at sufficiently hig h levels of development there are incentives for systematic R&D efforts. As a result, economies go through an industrial life cycle as they move from initial backwardness to industrial maturity. In other words, development an d growth are stages of a process of structural transformation characterized by changing patterns of capital accumulation, specialization by industry, and technological change.
