The A-dependence of z-scaling in inclusive hadron production in pA collisions at high transverse momenta is studied. The concept of z-scaling based on the fundamental principles of Nature such as self-similarity, locality, scale relativity and fractality reflecting the general features of particle interactions is applied for the description of processes of hadron production in pA collisions. The scalingfunction psi is expressed via the invariant cross-section Ed(3)sigma/dq(3) and the average multiplicity density dN/deta of particles produced at pseudorapidity eta=0 in the coresponding nucleon-nucleon interaction. The independence of the function psi(z) on the center-of-mass energy roots for particle production near 90 degrees in the NN c.m. system for different nuclei from D up to Pb is shown.
