  Using the numerical diagonalization method, we investigate the
one-dimensional $d$-$p$ model, simulating a Cu-O linear chain with strong
Coulomb repulsions. Paying attention to the effect of the transfer energy
$t_{pp}$ between the nearest neighbor oxygen-sites, we calculate the critical
exponent of correlation functions $K_{\rho}$ based on the Luttinger liquid
relations and the ground state energy $E_0(\phi)$ as a function of an external
flux $\phi$. We find that the transfer $t_{pp}$ increases the charge
susceptibility and the exponent $K_{\rho}$ in cooperation with the repulsion
$U_{d}$ at Cu-site. We also show that anomalous flux quantization occurs for
$K_{\rho}>1$. The superconducting region is presented on a phase diagram of
$U_{d}$ vs. $t_{pp}$ plane.
