The Shenzhen Stock Exchange has demanded that brokerages release information pertaining to any start-up firms that are looking to go public before it launches its new growth board, state media reported. The exchange also asked for suggestions about how it could make the new board successful and effective. The new fundraising platform comes after Chinese economists complained that there were too many obstacles preventing start-ups from selling their shares. The Shenzhen exchange's Small and Medium-sized Enterprise Board, established in 2004, currently requires companies to earn US$4 million during a three-year period, but is considering lowering that figure to US$1.3 million.
