“If you had asked me six months ago, I would probably have been on the fence,” Edwards said of the double-headers.
“Having experienced what we’ve experienced and the reaction to it all, at least for the next three or four years the double-header format would be the perfect way forward”.
The ECB also said they would address the pay disparity between the men and women’s players.
While the winners took home equal prize money, women’s salaries range from £3,600 to £15,000, while the men’s lowest pay bracket begins at £24,000.
The tournament was held at the same time as the domestic 50-over competition, meaning there has been no County Championship cricket since 11 July.
The lack of red-ball cricket for England’s men in the build-up to their Test series against India has been criticised.
“The whole point of growing the base of the sport is so you protect the things that are most precious to us and that is county cricket and Test cricket for us,” ECB chief executive Tom Harrison added.
“The reason why the Hundred has had a successful start is because it is electrifying content and stuff that people want to watch.
“At the end of the day, Test cricket is the pinnacle of the electrifying content you see played out around the world. Players are still judging themselves by their performances in the Test format.”
