iii) By using modern methods of production, industries contribute to better productivity and hence lower the cost of production of all goods produced. It, therefore, helps people to buy goods at a cheaper rate and help create demand for more products.
iv) Through such expansion of production, Industrialisation helps to absorb the labor force coming out of agriculture. Employment generation is therefore an important objective of industrialization.
