Ecclestone had wanted double points at the final three races of the season but the teams, who he called "bloody idiots", did not go for the plan.
"I'm not going to propose the three races again,"
he told the Independent.
"I'm going to let them get on with it. I don't know
what we're going to do next year."
Briton Lewis Hamilton leads the drivers' standings by 17
points from Mercedes team-mate Nico Rosberg going into the last race of the
campaign in Abu Dhabi on 23 November 2014.
If Rosberg wins, Hamilton will need to finish second to take
the title. Under the old system, sixth would have been enough.

Mercedes boss Toto Wolff said: "It would put a big
shadow over the championship if it was turned by a technical issue."
However, Ecclestone accused the teams of thinking about the
"short term" in not agreeing to his original plan of double points
for three races.
"One race is stupid but imagine if it was the last
three races," he said. "It means that somebody would have to have a
150-point advantage minimum to be sure they will win.
"The teams have not accepted it because they are bloody
idiots. They are all mechanics. They think of their team in the short term.
