Structural changes : Development of industries brings about a diversification in the production and consumption activities. Industrialisation brings about a shift from the production and consumption of wage goods (such as basic cereals, coarse cloth,) to the processed goods (such as fine varieties of cloth, processed food products). Such a transformation boosts economic growth and the standard of living in the country rises. On the other hand, Structural composition is made up of the contribution of different sectors to total GDP of an economy during a year. That is, the share of agricultural sector, industrial sector and service sector in GDP.
