The "apparent productivity of capital" only takes account of the factor of capital as the resource used. The term "apparent" recalls the fact that productivity depends on all the production factors (labour and capital) and on the way in which they are combined.
It is usually measured by relating the wealth created to the capital factor :
- the wealth created is measured by the added value (evaluated in volume) ;
- only the volume of capital used in the production process, i.e. the fixed productive capital, is taken into account.
