Income Increment results from the productive funds. There Is strict evtdence that this part Is proportional to the elasticity coefficient of replacing the labour with the funds and to the o normative coefficient of capital Investment efficiency £n. Then ~ the national Income Increment resulting from the Increase of ~ workers engaged In the material production will be somewhat lower than the 1abour productivity Indicator, I.e. It will equal not 27-3 v I ciL t-1 t-1 buta.Y' /4L' , t-1 t-1 wherea.Y' / .4L' Is not an aver;Jge t-1 t-1 but a top value of labour productivity. The latter shows. what would be the Increment of labour productivity If the capital/labour ratio at additional work~ng places were lower than at already existing working places. The top value of labour productivity can be expressed as EL = ~YL -E.,F>~L. In reality the labour productivity does not remain stable, It goes up. Simultaneously this Is accompanied by drawing additional capital Investment Into economic circulation which Increase the capital/labour ratio and organlzat!onal-technlcal level of production. This explains the fact that the total growth of Income actually exceeds that part which Is directly determined by additional expenditure of production resources utilized with unchanged basis efficiency. This part can be rightfully considered as an Increment value of normative net produce ( oY, ) w h I c h I s de f I n e d a s 6 Y = E ,..L + E n L N Increment of ~i+..t > = EoL + E.F, L N where 6F0 + Af =6F stands productive funds In year t as for the total compared to year t-1. The Increment of normative net produce could be Interpreted as the Increment of Income at the expense of extensive factors of economic growth. Then the Increment of Income on the basis on Intensive factors (6Yt) will equal (4) 
**Analysis**
The text discusses the relationship between income increment, labour productivity, and capital investment efficiency, suggesting that the growth of income is influenced by both extensive and intensive factors. The text also mentions the concept of normative net produce, which implies a focus on economic growth and development.
