英文摘要	We calculate the trispectrum in ghost inflation where both the contact diagram and scale-exchange diagram are taken into account. The shape of trispectrum is discussed carefully and we find that the local form is absent in ghost inflation. In general, for the non-local shape trispectrum there are not analogous parameters to tau(loc.)(NL) and g(NL)(loc.) which can completely characterize the size of local form trispectrum.
