Abstract
Using two volume-limited Main galaxy samples of the Sloan Digital Sky Survey Data Release 7 above and below the value of $ M_r^{*} $ we explore the environmental dependence of five photometric band concentration indexes. It is found that all the five band concentration indexes strongly correlate with local environment for all galaxies above and below the value of $ M_r^{*} $ high concentration galaxies exist preferentially in high density regions, while low concentration galaxies are located preferentially in low density regions.
