SHANGHAI (Reuters) - Most Chinese investors expect regulators to relax rules on initial public offerings (IPOs) by technology companies, and would like to invest in such domestic listings, the Shenzhen Stock Exchange said on Wednesday, citing a recent survey.

The exchange said its survey showed that nearly 90 percent of respondents said Shenzhen's start-up board ChiNext .CHINEXTP should strengthen its support to hi-tech firms.

Most investors are in favor of lowering financial threshold for their IPO, or accepting dual share classes, according to the survey.

The survey results, published on the exchange's website, fit with regulators' desire to bring home overseas-listed tech giants. Many of China's biggest tech companies, including Alibaba Group Holding Ltd BABA.N, Baidu Inc BIDU.O, JD.com Inc JD.O, and Tencent Holdings Ltd 0700.HK, are listed offshore.

China may allow its offshore-listed tech firms to sell a form of shares on the mainland, or China depositary receipts (CDRs), people with knowledge of the plan told Reuters last week.

Such a plan, if implemented, would pit Shanghai and Shenzhen against Hong Kong in the battle to host China’s tech giants.
