注册制改革对创业板股价波动的影响研究

Impact of Registration System Reform on GEB Stock Price Fluctuation

摘要: 注册制改革是我国推行资本市场深化改革的重要抓手,是证券市场的一项重大制度创新,涉及监管理念、上市条件、交易规则、投资者管理等方面。从2013年首次提出到2023年全面实行,“十年磨一剑”的注册制改革能否降低市场风险成为关注热点。本文选用2015—2022年创业板和中小板数据,以股价波动衡量市场风险,将创业板注册制改革视为“准自然实验”,构建双重差分模型(DID)进行实证研究,检验了我国注册制改革对创业板股价波动的影响。结果表明,在创业板试点注册制的过程中,没有引发市场的大幅波动,并且在一定程度上降低了股价波动性。

Abstract: Registration system reform is a key initiative for deepening reform in China’s capital market and represents significant institutional innovation in the securities market, encompassing regulatory concepts, listing conditions, trading rules, and investor management. From its initial proposal in 2013 to full implementation in 2023, whether the decade-long registration system reform can mitigate market risks has become a focal point of interest. This paper uses data from the Growth Enterprise Board (GEB) and the Small and Medium Enterprise Board from 2015 to 2022 to measure market risk through stock price fluctuation. Treating GEB registration system reform as a “quasi-natural experiment,” a Difference-in- Differences (DID) model is constructed for empirical research to examine the impact of China’s registration system reform on GEB stock price fluctuation. The results indicate that the GEB pilot registration system did not trigger significant market fluctuations and, to some extent, reduced stock price volatility.
