This research is conducted to quantitatively measure the relationship between corruption and public investment at municipalities’ level in Indonesia. According to Nash Equilibrium derived from mixed strategies, the relationship between corruption and public investment can be both positive and negative depending on the level of the corruption Index. Moreover, the econometric estimations from cross section data and pooled data consistently confirm that the relationship between corruption and public investment is in non linear quadratic form. It was found that the public investment reaches the lowest level when the corruption index ranges from 4.42-4.64.
