What is a system based on the use of machines rather than on animals or human power

The system defined is a capital-intensive production system.

Producing requires the combination of the so-called factors of production: land, labor and capital. When production relies, in a higher proportion, on capital accumulation and the usage of machines in large production plants, rather than on human force, it is a capital-intensive production system.

If, on the other hand, production relied, in a higher proportion, on an extense labor force it would be a labor-intensive production system.
