The Economist reports on the relationship between technological leapfrogging in developing countries and sustained development. The case is argued that basic infrastructure and the development of human capital cannot be ignored,and in fact, is a prerequisite for a larger scale
diffusion of technology in these societies. Mobile phones are the exception.
A few quotes from these articles:
Building a fibre-optic backbone or putting plasma screens into schools may be much more glamorous than building electrical grids, sewerage systems, water pipelines, roads, railways and schools. It would be great if you could always jump straight to the high-tech solution, as you can with mobile phones. But with technology, as with education, health care and economic development, such short-cuts are rare. Most of the time, to go high-tech, you need to have gone medium-tech first.
Broadly, two sets of obstacles stand in the way of technological progress in emerging economies. The first is their technological inheritance. Most advances are based on the labours of previous generations: you need electricity to run computers and reliable communications for modern health care, for instance. So countries that failed to adopt old technologies are at a disadvantage when it comes to new ones. Mobile phones, which require no wires, are a prominent exception... The other set of problems has to do with the intangible things that affect a country's capacity to absorb technology: education; R&D; financial systems; the quality of government. In general, developing countries' educational levels have soared in the past decade or so. Middle-income countries have achieved universal primary-school enrolment and poor countries have increased the number of children completing primary school dramatically. Even so, illiteracy still bedevils some middle-income countries and many poor ones.
Development is a hard slog.
