Technical Composition of Capital, the ratio of the mass of the means of production to the number of workers operating them. It can be expressed by a number of indicators: the quantity of electricity (in kw/hrs), motor power (in HP) per worker, the amount of raw materials processed by the worker (in kg, t), etc. Means of production are the result of the past labour of the worker. To set them in motion, the worker has to expend living labour. Thus, the technical composition of capital expresses the ratio of past labour to the living labour required for using the means of production at the given level of the productive forces and characterises the physical composition of production. As the social labour productivity grows, the technical composition of capital increases, too, because every worker expends more means of labour and processes more raw materials than before. The change in the technical composition of capital leads, as 354 a rule, to a change in its value composition. The organic composition of capital changes too.
