This paper, investigates the threshold effect of increasing non-oil exports on energy intensity in selected of OPEC member countries for the period of 1995-2012, using panel smooth transition regression (PSTR) model as one of the most prominent regime-switching models. For this end, the non-oil exports variable is used as a transition variable. The linearity test results indicate clearly nonlinear relationship among variables under consideration. Moreover, nonexistence of remaining nonlinearity relationship justifies considering one transition function and one threshold parameter, which shows a two regime model. In this study slope parameter is 21/1681 and threshold value is 8/4715. In the first regime exports has a negative impact on energy intensity and by transition of threshold value and entry to second-regime negative impact has been decreased. Therefore increasing exports decreases energy intensity in this countries.
