Modern industrial activities in developed countries are characterised by several major trends that have transformed the manufacturing landscape.

First, mechanisation and automation have become dominant features. Automation represents the advanced stage of mechanisation, where automatic factories with feedback and closed-loop computer control systems have been developed. These machines are designed to 'think', reducing human intervention in the manufacturing process.

Second, technological innovation through research and development has become essential. This strategy focuses on quality control, eliminating waste and inefficiency, and combating pollution, making industries more sustainable and efficient.

Third, there is extreme specialisation and division of labour. Modern manufacturing involves complex machine technology where workers specialise in specific tasks. This allows production of more goods with less effort and at lower costs. It also requires vast capital, large organisations, and executive bureaucracy to manage large-scale operations.

Fourth, developed countries have witnessed uneven geographic distribution of industries. Major concentrations of modern manufacturing have flourished in only a few places, covering less than 10 per cent of the world's land area. These nations have become centres of economic and political power. Regions like Western Europe and eastern North America have highly developed transport systems that have induced concentration of industries.

Finally, there has been a shift in energy sources. While coal was earlier the main source of energy, today hydroelectricity and petroleum have become important sources for many industries in developed countries.
