  A linear correlation is shown quantitatively between the magnitude of the EMC
effect measured in electron deep inelastic scattering (DIS) and the nuclear
residual strong interaction energy (RSIE) obtained from nuclear binding energy
subtracting the Coulomb energy contribution. This phenomenological relationship
is used to extract the size of in-medium correction (IMC) effect on deuteron
and to predict the EMC slopes $|dR_{EMC}/dx|$ of various nuclei. We further
investigate the correlations between RSIE and other quantities which are
related to the EMC effect. The observed correlations among RSIE, EMC slope and
SRC ratio $R_{2N}N_{total}/N_{np(^3S_1)}$ imply that the local nuclear
environment drives the modification of quark distributions.
