In economics, productivity is defined as the ratio, in volume, between production and the resources used to obtain that production.
Production means goods and/or services produced. The resources used, also called production factors, mean labour, technical means (installations, machines, tooling, etc.), the capital invested, intermediate consumption (raw materials, power, transport, etc.) as well as factors less easy to grasp but extremely important, such as the accumulation of know-how.
Productivity can also be calculated in relation to a single type of resources such as labour or capital. Then we speak about apparent productivity.
The apparent productivity of labour is a widely used measurement. The apparent productivity of capital can also be calculated.
