  A scale-invariant chiral effective Lagrangian is constructed for octet pions
and a dilaton figuring as Nambu-Goldstone bosons with vector mesons
incorporated as hidden gauge fields. The Lagrangian is built to the
next-to-leading order in chiral-scale counting without baryon fields and then
to leading order including baryons. The resulting theory is hidden
scale-symmetric and local symmetric. We also discuss some possible applications
of the present Lagrangian.
