A new method which is convenient for the phenomenological analysis to explore the mutual correlations among various pion reactions is presented based on the S matrix formalism. We first study the general properties of the S matrix as it is necessary for practical purposes. Next, utilizing the results we d,iscuss the intimate correlations between the photo-meson pro duction and pion-nucleon scattering. The results seem to be promising in that it can correctly give the ratio: (at 130 Mev) which can never be deduced from the Jowest order perturbation theory. Finally, we apply this method to th~ qualitative investigation of another process, i.e. the elastic nucleon-nucleon scattering at extremely high energies, from which we can conclude that the scattered nucleons will be concentrated in the forward and backward directions in the centre of mass system.
