Views, concepts, and methods of stand harvest regulation are reflection of the level of knowledge on the role and potentials of forest economy in fulfilling various social needs connected with the forest. It is thus a very complicated problem, requiring reconciling of many functions, and simultaneously maintaining the rule of sustainability of forest use. The work was mainly concentrated on requirements of market economy in regard to stand use. To that end the demand for wood was first discussed, taking into account that it is a derivative or conditional demand, forming usually several transition degrees. The shape of wood supplies in the conditions of fully free market is the second fact equally important. It is worthy to note that wood supply differs depending on the time period, i. e. on short or long or even very long term. Individual wood market types are however rarely perfectly competitive markets, and this fact causes as a rule a deep engagement of state authorities in establishmentof not only stand use rules but also in direct management of growing stock, especially in state forests. In this matter the state follows most frequently the rule, traditionally conceived, of forest production continuity and sustainable use of forest resource, that in practice is reduced to a rule of harvesting more or less stable amounts of raw wood material. The main arguments for the stand use regulation conceived in such a way are, i.a., as follows: national security, commitnents of moral nature, potentials of multiple use of forests, lessening the silvicultural risk, and economic stability. Along the development of advanced computer technique there have been models worked out enabling to estimate alternative strategies of forest harvest, resulting in abandoning the traditional concept of maintaining the raw wood harvest size being stable in volume terms.
