The connection between technological change and economic growth is generally explained within a framework provided by a macro-economic production function where output depends on labour and capital. The shortcomings of such an approach are critically examined. It is argued that technology is not merely a production phenomena but embraces all aspects of human activity which should be incorporated in a technology-growth model. The contribution of colonization, slavery, migration and discovery of cheap oil and gas to technological change and economic growth in the developed countries should be thoroughly analyzed to explain the actual process of their development. Historical experience of the interaction between crop and livestock sectors in the process of development of these countries also need to be understood for developing appropriate technology in the less developed countries
