Actually the reverse happened in 70s - instead of pursuing indigenous R&D, it was decided to clone Western hardware and software instead. This really crippled Soviet computer science and engineering.
In 50s-60s Soviet computers were not that far behind, but late it was harder and harder to compete with West simply because of economy scale disadvantage. Unlike nukes and space exploration, computer technology was not receiving the funding to maintain parity.
Therefore it was decided that copying and cloning Western tech would be cheaper then trying to compete in yet another high-tech industry.
And of course things were harmed by the party politics. A Polish engineer invented a computer which is now considered to be few years ahead of its time, and was ready to enter production,but then it was shut down because of a direct order from the party,as it would conflict with the party-backed Elwro company.
Interesting how facing competition, following the others (between nations, or even companies) ideas is rarely a worthy plan for long term. It's depriving your brains of real pressure to invent.
