A realspace renormalizationgroup approach is developed to calculate hopping conductivity of ThueMorse(TM) nanostructured chain. It is found that the kinds and the sizes, as well as the interface structures and lattice distortion of nanograins have a notable effect on the hopping conductivity of nanostructured systems. From the effect of the degree of random on hopping conductivity, TM chain is a system between Fibonacci and periodic sequence.-
