The behavior of two-dimensional Lagrangian field theory under the conformal transformations is investigated and compared with the larger dimensional case. It is shown that there exists a close parallelism between both cases, in spite of the very large difference between the structures of their respective conformal groups. The only novel feature of the two-dimensional case is an additional condition (σ_<++>=σ_<-->=0) for the full conformal invariance of Lagrangian. The same condition is also necessary for the existence of the "improved energy-momentum tensor", even if we consider only the transformations of the subgroup corresponding just to the full group in the larger dimensional case.
