MOSCOW, FEB. 6 -- Nicholai Talyzin has been transferred from planning commissioner of the Soviet Union to another post, the official news agency Tass reported today.

Talyzin, one of the senior officials appointed by Mikhail Gorbachev's Kremlin leadership to introduce the new Soviet economic reforms, has been appointed chairman of the government bureau for social development, Tass said.

Yuri Maslykov was named the new chairman of the state planning commission, called Gosplan. Maslykov was chief of the government's military-industrial commission.

The replacement of Talyzin is viewed by western analysts here as a signal that the Kremlin is dissatisfied with the pace of introducing reforms, and is placing the blame on senior level personnel.

In a speech last June, Gorbachev attacked Talyzin and other senior economic officials for not recognizing shortcomings in the Soviet economy. The public criticism was viewed as a warning to Talyzin, 59, that his job could be in jeopardy.

The appointment of Maslykov is considered the latest in a series of signals that officials from the smooth-running Soviet military-industrial sector are being called on to remedy the woes of the civilian sector.

Talyzin will keep his seat as first deputy prime minister. The bureau for social development handles varying issues, such as housing, transportation and youth.

Maslykov, 51, was also appointed a first deputy prime minister today. He has spent his career as a planner in the defense industry.

The Soviet defense industry is said to function more efficiently than the moribund civilian economy. In recent months, other senior defense officials have been transferred to work in different sections of the civilian economy.

The shake-up at Gosplan could be the result of a close analysis of the performance of the new economic reforms. The reforms have been introduced gradually since Gorbachev came to power three years ago and are expected to undergo close observation at a major conference of the Soviet Communist Party in June.
