	%X This paper shows that the economy of any country
can be presented as three different shells such as: economic shell of a
big, a medium and a small business. The new concepts were
introduced such as: volume of an economic shell, coefficient of
shell-s expansion (compression) etc. These shells can expansion or
compress under action by internal or external powers and when shell
expansions - it means the rising of a business activity and
compression shows us that economy goes on recession. This process
of an expansion or a compression can develop in the various ways
like linear, logarithm or any other mathematical laws.
