However, in practice this meant that investment was shifted towards new branches of industry, including the electronics, computing, automotive and nuclear power sectors, leaving the traditional heavy industries dependent upon older technologies. Despite the rhetoric about modernization, innovation remained weak as enterprise managers preferred routine production that was easier to plan and brought them predictable bonuses.
