中国市场的参考依赖偏好与风险收益权衡
文章 arXiv papers · 作者: Penggan Xu
总结
本研究在中国市场复现了关于参考依赖偏好与股票收益的既有研究,并使用资本利得悬置(CGO)作为投资者未实现盈亏的代理指标。研究考察 CGO 与五种风险度量之间的关系:市场贝塔、收益波动率、特质波动率、公司年龄和现金流波动率。样本据称涵盖 1995 至 2024 年的中国股票;分析使用依赖型双重排序和 Fama-MacBeth 回归研究横截面收益。
报告结果显示,高 CGO 公司中的正向风险收益关系较弱或不存在,而低 CGO 公司中的正向关系更强。在中国,CGO 与风险度量之间的交互作用主要为负,这与美国报告的正向影响不同。作者结合中国的散户参与、投机活动和监管环境解释这一差异,并认为参考点在中国可能不那么重要。这些是针对特定市场和时期的复现结果;摘录没有提供详细估计值或稳健性检验,并提醒不要假定该模式可推广到其他市场。
核心观点
- 使用 CGO 作为中国股票投资者未实现盈亏的代理指标。
- 研究将 CGO 与贝塔、收益波动率、特质波动率、公司年龄和现金流波动率一并检验。
- 报告结果显示,高 CGO 公司中的正向风险收益关系弱于低 CGO 公司。
- 在中国,CGO 与风险度量的交互作用大多为负,与美国的报告结果形成对比。
- 作者认为,市场结构和投资者行为可能影响参考依赖在不同市场中的表现。

# Replication of Reference-Dependent Preferences and the Risk-Return Trade-Off in the Chinese Market # Replication of Reference-Dependent Preferences and the Risk-Return Trade-Off in the Chinese Market This study replicates the findings of Wang et al. (2017) on reference-dependent preferences and their impact on the risk-return trade-off in the Chinese stock market, a unique context characterized by high retail investor participation, speculative trading behavior, and regulatory complexities. Capital Gains Overhang (CGO), a proxy for unrealized gains or losses, is employed to explore how behavioral biases shape cross-sectional stock returns in an emerging market setting. Utilizing data from 1995 to 2024 and econometric techniques such as Dependent Double Sorting and Fama-MacBeth regressions, this research investigates the interaction between CGO and five risk proxies: Beta, Return Volatility (RETVOL), Idiosyncratic Volatility (IVOL), Firm Age (AGE), and Cash Flow Volatility (CFVOL). Key findings reveal a weaker or absent positive risk-return relationship among high-CGO firms and stronger positive relationships among low-CGO firms, diverging from U.S. market results, and the interaction effects between CGO and risk proxies, significant and positive in the U.S., are predominantly negative in the Chinese market, reflecting structural and behavioral differences, such as speculative trading and diminished reliance on reference points. The results suggest that reference-dependent preferences play a less pronounced role in the Chinese market, emphasizing the need for tailored investment strategies in emerging economies.
