This paper, in "Part I--Trends in Industrial Development"--notes that industrial development is continuing in developing countries, but with such discontinuity, diversity, and selectivity that generalizations are difficult. In the first development decade (the 1960's), industrialization did not fulfill expectations, and gaps in economic status widened. The modernization trend increasingly incorporated orientation to the future, but emphasis on growth lessened while emphasis on environmental consequences intensified, and the post-industrial service sector assumed major importance. Regional and global theaters of development gained in importance; and economic, social, and biological philosophies were blended in the revival of ecological values. "Part II--Industrialization: Implications for Other Sectors"--surveys the classical model of impact, growth of population, distribution of population, poverty and the maldistribution of income, occupations and employment, and infrastructure. "Part III--Concluding Note" discusses some major implications, such as industrialization is a necessary but insufficient contribution in the development of developing countries. A 44-item bibliography is appended. (NH)
