Abstract: Taking China's A-share IPO company as a sample from 1993 to 2015, and examines the effect of China's previous IPO system reforms on the incremental reform of China's capital market IPO system, and further studies the earnings management. The mediating role played by the role of both. The study found that the reform from the quota management to the indicator management stage did not have a significant impact on the IPO pricing efficiency. The other stages of the reform effectively improved the IPO pricing efficiency in the short window period, and the IPO company's earnings management started in the process. It has reached a significant intermediary role. In addition, further research also found that the IPO system reform has reduced the IPO pricing efficiency in the medium and long-term window, and the IPO system reform has different effects on IPO pricing efficiency in different marketization regions and the bull market. The research in this paper provides a reference for strengthening the supervision of IPO company's earnings management during the IPO registration system reform process.

Key words: IPO company, IPO system reform, earnings management, IPO pricing efficiency, mediating effect
