#### abstract

Two different strategies of the relativistic quantum theory construction are considered and evaluated. The first
strategy is the conventional
strategy, based on application of the quantum mechanics technique to relativistic
systems. This approach cannot solve the problem of pair production. The apparent success of QFT at solution of this
problem is conditioned by the
inconsistency of QFT, when the commutation relations are incompatible with
the dynamic equations. (The inconsistent theory "can solve" practically any
problem, including the problem of pair production). The second strategy is based on application of fundamental principles of classical dynamics and
those of statistical description to relativistic dynamic systems. It seems to be more reliable, because this strategy does not
use quantum
principles, and the main problem of QFT (join of nonrelativistic quantum principles with
the principles of relativity) appears to be eliminated.
