“…Sometimes one can also speak about the general purpose technologies(Bresnahan and Trajtenberg 1995; Helpman 1998; for a detailed analysis of this theory, seePolterovich 2009). The meaning of this concept is close to the technological mode, but the meaning of the former concept is still narrower than the latter one, since there can be several general purpose technologies within one mode.3 See, e.g.,Schumpeter 1939;Freeman 1987; Rumyantseva 2003: 12-14; Glazyev 1993: 95-111; Ivanova 2003: 210; Papenhausen 2008: 789;Akayev et al 2012. In fact, as in any classification there are numerous differences in the main characteristics of some or other modes, e.g., some researchers 'attribute' such transitionary areas of innovations like automobile to the third wave, the others -to the fourth K-wave, etc.…”
