  We introduce the concept of $k$-(semi)-dilation for Liouville domains, which
is a generalization of symplectic dilation defined by Seidel-Solomon. We prove
that the existence of $k$-(semi)-dilation is a property independent of fillings
for asymptotically dynamically convex (ADC) manifolds. We construct examples
with $k$-dilations, but not $k-1$-dilations for all $k\ge 0$. We extract
invariants taking value in $\mathbb{N} \cup \{\infty\}$ for Liouville domains
and ADC contact manifolds, which are called the order of (semi)-dilation. The
order of (semi)-dilation serves as embedding and cobordism obstructions. We
determine the order of (semi)-dilation for many Brieskorn varieties and use
them to study cobordisms between Brieskorn manifolds.
