Self-similarity of jet production in pp and pp¯ collisions is studied in the framework of z-scaling. Inclusive jet transverse momentum distributions measured by the STAR Collaboration at RHIC, the CDF and D{} Collaborations at Tevatron and the CMS and ATLAS Collaborations at LHC are analyzed. The experimental spectra are compared with next-to-leading order QCD calculations in pT - and z-presentations. It is shown that self-similar features of jet cross sections manifested by z-scaling give strong restriction on scaling function ψ(z) at high z. New results on the energy and angular independence and the asymptotic behavior of ψ(z) are discussed. The obtained results are considered as confirmation of self-similarity of jet production, fractality of hadron structure and locality of constituent interactions at small scales
