As well as the "not using best efforts" charge, the players were also accused of "conducting oneself in a manner that is clearly abusive or detrimental to the sport".
Their places in the last eight will be taken by the pairs who finished third and fourth in the qualifying groups concerned.
Some players had blamed the introduction of a round-robin stage rather than a straight knockout tournament as the catalyst. In the round-robin format, losing one game can ultimately lead to an easier match-up in the next round. However, one Chinese player said their actions were due to them trying to preserve energy ahead of the knockout stages.

In the first women's doubles match at Wembley Arena on Tuesday night, fans jeered China's
and South Koreans
The longest rally in the first game lasted only four shots, with match referee Thorsten Berg appearing on court at one point to warn the players. South Korea won the
Group A match,
which lasted 23 minutes, 21-14 21-11.
Both pairs knew the winners would face China's Tian Quing and Zhao Yunlei. With Yu and Wang losing, the two Chinese pairings could have only met in the final.
Speaking before the disqualification verdict was released, South Korea's coach Sung Han-kook, said: "The Chinese started this. They did it first."
But Yu said the Chinese were aiming to preserve energy ahead of the knockout stages. "This is the first time we've played them and tomorrow it's the knockout rounds, so we've already qualified and we wanted to have more energy for the knockout rounds," she said.
A later match between South Korean third seeds
and Indonesian pair
was played out in a similar atmosphere.
Referee Berg returned to court and brandished the black card, signalling disqualification, but it was rescinded and the match resumed when the Indonesians protested.
Both pairs had also already qualified for the knockout stages, with the winners of Group C to play Yu and Wang and the Korean pairs to face each other if Ha and Kim lost. The Koreans won 18-21 21-14 21-12.
Gail Emms, a badminton Olympic silver medallist for Great Britain in 2004, who was at the event for BBC Sport, said: "I'm furious. It is very embarrassing for our sport.
"This is the Olympic Games. This is something that is not acceptable. The crowd paid good money to watch two matches."
