The invention discloses a power distribution network elasticity evaluation method and device, electronic equipment and a readable storage medium, relates to the technical field of power systems, and solves the problem of influence on the elasticity level of a power distribution network due to access of a distributed power supply and/or distributed photovoltaic. According to the parameter information, elastic evaluation indexes including a static index and a dynamic index are constructed, the static index comprises a line risk parameter and a relative average path length of power distribution network island operation, and the dynamic index comprises a line risk parameter and a relative average path length of power distribution network island operation; the dynamic indexes comprise a load loss rate, a load loss rate, an island power supply coverage rate, a branch load average change rate and a voltage average offset rate; and based on an analytic hierarchy process, an entropy weight method and a superior and in
