• 详情 Memory-induced Trading: Evidence from COVID-19 Quarantines
    This study investigates the role of contextual cues in memory-based decision-making within high-stakestrading environments. Using trade records from a large Chinese brokerage firm and a novel dataset on COVID-19 quarantines, we find that quarantine periods trigger the recall of previously traded stocks, increasing the likelihood of subsequent orders for those stocks. The observed patterns align more closely with similarity-based recall than with alternative channels. Welfare analysis reveals that these memory-induced trades lead to an annualized loss of approximately 70 percentage points for the representative investor’s portfolio. We also find evidence at the market level: when the geographical distribution of quarantine risks is recalled, the probability of recalling the cross-sectional stock return-volume distribution from the same day increases by 1.6 percentage points. This study provides causal evidence from a real-world setting for memory-based theories, particularly similarity-based recall, and highlights a novel channel through which COVID-19 policies affect financial markets.
  • 详情 QFII-Invested Mutual Fund Managers: Learning from Domestic Peers
    This paper investigates how foreign institutional investors, specifically Qualified Foreign Institutional Investors (QFIIs), influence the investment strategies of Chinese mutual fund management companies (FMCs) in which they hold shares. By analysing panel data from 1,766 mutual funds managed by 44 foreign-invested FMCs in China between 2005 and 2021, we explore whether QFII-invested FMCs (Q-FMCs) learn more from their domestic counterparts (D-FMCs) than other foreign-invested FMCs (NQ-FMCs). Our findings show that Q-FMC-managed mutual funds exhibit portfolio allocations more closely aligned with local DFMCs than those managed by NQ-FMCs. This imitation is particularly pronounced when selecting new stocks, enhancing portfolio performance, but not when rebalancing existing positions. Additionally, Q-FMCs trade more actively than NQ-FMCs. Robustness checks confirm these results across various ownership structures, fund characteristics, market conditions, and regulatory changes. These findings highlight the dual role of QFIIs as both investors and learners in China’s evolving financial landscape, offering insights into how foreign capital integrates into emerging mutual fund markets, informing regulatory policy aimed at fostering cross-border financial development.
  • 详情 Does data governance-driven financial regulation affect bank risk-taking?
    We exploit a unique financial regulatory tool with data-governance functions as a quasi-natural experiment to explore the determinants of bank risk-taking. The paper finds that Examination Analysis System Technology (EAST) reduces bank risk-taking. This result is more pronounced in banks with higher capital adequacy ratios and higher liquidity levels. We also find that the inhibitory effect of EAST on bank risk is more significant for banks in eastern regions and listed banks. Our findings highlight the positive impact of data regulation on promoting financial stability.
  • 详情 “双碳”与共同富裕目标下市场型环保规制的分配效应 ——来自碳排放权交易试点的县域证据
    在实现“双碳”与共同富裕目标并进的背景下,环保规制的公平后果日益受到关注。本文以2013、2014与2016年分批启动的碳排放权交易试点为准自然实验,基于2000—2023年中国区县面板数据,系统评估市场型环保规制的分配效应。结果变量方面,本文使用区县夜间灯光构建的不平等指标(基尼、泰尔、阿特金森)刻画县域经济活动分布,并以县域城乡居民收入对数差距作为补充。识别策略方面,除区县与年份双向固定效应的TWFE-DID外,进一步引入适用于分批采用的更强识别方法:(1)Sun-Abraham分组事件研究用于动态效应检验并规避传统事件回归在异质处理效应下的加权偏误;(2)Callaway-Sant’Anna ATT(g,t)在“尚未受处理/从未受处理”对照组框架下估计分组—时期平均处理效应;(3)合成双重差分(SDID)同时估计单位权重与时间权重,以匹配处理前趋势并降低对严格平行趋势的依赖。研究发现:在TWFE-DID下,试点显著降低了县域夜间灯光基尼与阿特金森指数;更强识别(ATT(g,t)、SDID)在城市层面同样指向夜间灯光泰尔指数的下降,但幅度更为温和。机制检验表明,试点显著降低城市单位GDP能耗,支持“绿色转型—要素再配置—分配格局改善”的作用链条。
  • 详情 周易“变易-不易”思维下的能源系统韧性、六爻风险矩阵与ESG预警: 基于动态模型的实证研究
    本文基于2007—2022年中国上市能源相关企业面板数据(46,424个企业—年度观测值),研究极端气候与政策冲击背景下ESG风险暴露对企业能源系统韧性的影响及其动态传导机制。本文构建阶段敏感的离散风险状态表示方法,把《易经》中“变易—不易”的结构思想转化为可操作的计量框架,将企业风险映射为六个生命周期阶段下的64种状态结构,并在企业与年份固定效应框架下识别风险效应的阶段异质性。结果表明,原煤依赖度显著降低绿色转型指数(韧性指标),天然气依赖度显著提高韧性;标准煤当量能源强度在煤炭暴露与韧性之间发挥重要中介作用,占总效应的62.3%。进一步构建马尔可夫状态转移模型,发现极端事件显著改变高风险状态向低韧性状态的转移概率。结合LSTM-注意力机制生成预警概率,在最优阈值下样本外预测准确率为78.6%,稳健性检验结果一致。基于预警概率构建阶段相关的对冲规则,结果显示其在后期阶段显著降低风险暴露并提高风险调整后收益。本文为能源企业转型期风险管理与政策干预提供了可操作的识别框架与决策依据。

  • 详情 Why Bad Performing Mutual Funds Remain Popular?
    The flow-performance relation in China’s mutual fund market differs from that in developed markets (e.g., the U.S.). We find that investors actively allocate capital to poorly performing funds, generating a negative relation at the bottom of return distribution. These flows are driven mainly by increased purchases rather than reduced redemptions. We then examine the mechanisms behind this anomaly. First, investors act on rational expectations of performance reversals, with this pattern being more pronounced among funds with higher activeness. Second, product differentiation attracts heterogeneous investors when performance is weak. Third, marketing and fund family effects serve as simple signals that amplify inflows. Overall, our study provides new empirical evidence on fund investor behavior and its economic consequences in an emerging market context.
  • 详情 When Retail Investors Strike: Return Dispersion, Momentum Crashes, and Reversals
    We introduce a real-time dispersion measure based on cross-sectional stock returns explicitly designed to capture retail-driven speculative episodes. Elevated return dispersion effectively identifies periods characterized by intensified retail investor trading behaviors, driven by salience, diagnostic expectations, and extrapolative beliefs. During these high-dispersion states, momentum strategies collapse, and short-term reversals become dominant. Conditioning momentum strategies on our dispersion measure resolves the longstanding puzzle of missing momentum in retail-intensive markets such as China, substantially enhancing profitability. A dynamic rotation strategy between momentum and short-term reversal portfolios guided by dispersion states achieves annualized Sharpe ratios nearly double those of static approaches. Extending our analysis internationally, we employ Google search trends as proxies for retail investor attention, confirming that dispersion robustly predicts momentum and reversal returns globally. Our findings underscore the behavioral channel through which retail-driven speculation conditions momentum dynamics, providing clear implications for dynamic portfolio management strategies.
  • 详情 Intangible Capital and Firm Markups: Evidence from China
    This study theoretically and empirically examines the impact of intangible capital on firm markups. The current research follows Altomonte et al. (2021) and first establishes a theoretical framework of intangible capital affecting firm markups. Accordingly, this study finds that an increase in intangible capital results in an increase in firm markups via the “production efficiency” channel but a decrease in firm markups via the “market-based pricing” channel. We use the data of Chinese manufacturing firms to further empirically study the influence of intangible capital on firm markups and its influencing mechanism. After a series of robustness and endogeneity tests, this research finds that intangible capital is conducive to increasing firm markups. Results of the empirical analysis also reveal that the positive impact of an increase in intangible capital on the markups of Chinese manufacturing firms via the “production efficiency” channel are higher than the negative impact of an increase in intangible capital via the “market-based pricing” channel. Moreover, the impact on the markups of different types of firms are not the same, with significant heterogeneity characteristics. This study provides micro evidence from a large developing country on how intangible capital affects the change in firm markups, thereby providing a new perspective on the economic effects of intangible capital.
  • 详情 Timing the Factor Zoo via Deep Visualization
    We develop a deep-visualization framework for timing the factor zoo. Historical factor return trajectories are converted to two complementary image representations, which are then learned by convolutional neural networks (CNNs) to generate factor-specific timing signals. Using 206 equity factors, our CNN-based forecasts deliver significant economic gains: timed factors earn an average annualized alpha of about 6\%, and a high-minus-low strategy yields an annualized Sharpe ratio of 1.22. The outperformance is robust to transaction costs, post-publication decay, and factor category-level analysis. Interpretability analyses reveal that CNNs extract predictive signals from path boundaries and regime shifts, capturing patterns orthogonal to investor attention.
