Metallicity and its relationship with other galactic properties is a fundamental probe of the evolution of galaxies. In this work, we select about 750,000 star-forming spatial pixels from 1122 blue galaxies in the Mapping Nearby Galaxies at Apache Point Observatory survey to investigate the global stellar mass-local stellar mass surface density-gas-phase metallicity (M-*-Sigma(*)-Z) relation. At a fixed M*, the metallicity increases steeply with increasing Sigma(*). Similarly, at a fixed Sigma(*), the metallicity increases strongly with increasing M-* at the low-mass end, while this trend becomes less obvious at the high-mass end. We find the metallicity to be more strongly correlated to Sigma(*) than to M-*. Furthermore, we construct a tight (0.07 dex scatter) M-*-Sigma(*)-Z relation, which reduces the scatter in the Sigma(*)-Z relation by about 30% for galaxies with 7.8.
