DM/m3. In the said business year the cut in average was 3.2% larger than previous
year (in private forests the cut was + 7%, in state forests +4.9%), and in
corporate forests -4.1% to previous year).


In all types of ownership the cut was close to the allowable cut, with the exception
of1990, when due to storm damages the cut was double of allowable
annual cut..


Corporate and private ownership enjoy multiple state subsidies in money
and kind, the income statements of net results without these subsidies are called
net income I, and with subsidies net income II respectivelly. In corporate
forests in the period 1989-97 net income I. was postive only in 1990, when an
average 12.3 m´/ha was cut; in private forests in the same period net income I.
was negative in 1992 and 1993. In corporate forests net income II, in spite of
subsidies was positive only in 1989, 1990, 1994, 1995, and in 1997. In the state
forests, with the exception of 1980, 1981, and 1990, net income was always
negative, and is conered in principle from the lands ´and federal s budget.


The results of business operations of all types of ownership and size of
holdings, predominant species and volume of timber cut differ.


The way of subsidizing differs, and it is the result of carefully defined forest
and economic policy. The conversion of forests towards close to nature stands,
afforestation of agricultural land of marginal productivity, fighting tree diseases,
forest fires, etc. are among primary targets of policy of supporting
forestry. In the same way the marketing and promotion of use of wood as ecologically
cleanest material in construction, and other fields of application are
supported as well.


Since the annual average growth of all German forests is about 5.9 mVha,
and that positive operations, without losses and subsidies, are possible only in
stands predominantly spruce with a high proportion of logs of 7.5 m´/ha, obviously
the solution of the problem should befind in cutting costs.


It is established by econometric analysis that in production function where
annual average cut (Q) is dependent variable, machines and transportation
equipment applied in DM per ha (capital, K), and labour in hours/ha (L) as independent
variables, of all deviations, in state forests 9.5%), 18%) in corporate,
and 33% in private forests, might be explained by production functions, which
are withih 95%> confidence interval, significant only in case of production
functions for corporate and private forests. From these empirical production
functions comes obviously out that substituibility od labor is very high compared
with capital equipment applied. Significant investments in German forestry
support the conclusion of this analysis. Very low percentage of deviations
explained in case of state forests seems logical, since the state ownership
has a lot more of social responsibilities than other ownership types, which at
the level of forest range, as well as in higner levels, gives services, free of charge
or discounted, to all other forest owners.


The supply/demand equation is only in one case significant. Only small
part of deviations is explained by empirical demand equation, since the demand
and sale prices run parallel, except in 1990 due to the increased supply
of timber damaged by storm, which proved the value of analysis performed.


Key words: Economic achievements, production functions demand
functions.
