This paper analyzes the impact of monthly stock recommendations by securities companies on investor sentiment; it then creates a quantitative stock selection investment strategy based on the developed sentiment indicators and Rainbow algorithm, named the Rainbow Algorithm Strategy with Integrated Technical and Sentiment Indicators (TS-RA Strategy). Results show that the stock recommendation factor exhibits good and stable stock selection ability, and the TS-RA Strategy constructed on this basis demonstrates high profitability. During the testing period, the annualized return reached 25.58%, with a maximum drawdown of 7.41%, indicating high returns and manageable risks. Furthermore, the TS-RA Strategy is superior to the investment strategy constructed using deep Q-learning methods and has performed well in different market environments.

Constructing a Relative Deprivation Index of household consumption using data from the China Household Finance Survey (CHFS), we examine the impact of local government debt on household consumption inequality and its underlying mechanisms. We find that explicit local government debt significantly exacerbates household consumption inequality, whereas implicit local government debt has a considerably mitigating effect. The mechanisms through which local government debt affects consumption inequality are analyzed from the perspectives of income inequality, liquidity constraints, and household leverage ratios. In terms of the debt formation process and the structure and efficiency of fund utilization, several factors, such as the government's intervention capacity, will have differentiated impacts on the economic effects of local government debt.
本文利用中国家庭金融调查(CHFS)数据构建了家庭消费的相对剥夺指数,考察了地方政府债务对家庭消费不平等的影响及其潜在机制。我们发现,显性地方政府债务显著加剧了居民消费不平等,而隐性地方政府债务则有显著的缓解作用。从收入不平等、流动性约束和居民杠杆率三个角度分析了地方政府债务影响消费不平等的机制。在债务形成过程、资金使用结构和效率方面,政府干预能力等因素会对地方政府债务的经济效应产生差别化影响。

This study examines the relationship between board independence and share-pledging behavior by controlling shareholders (promoters) in Indian listed firms from 2010 to 2020 using a balanced panel. Further, we examine the interplay between the independence of the board and the presence of the promoter as an executive director on the board and its impact on the share pledging by promoters. Our findings reveal that independent boards serve as a deterrent to share pledging by promoters, especially when independent directors actively participate. However, this deterrent effect diminishes when promoters hold executive positions on the board. Moreover, unlike business group firms, board independence fails to deter share pledging in concentrated standalone firms. Furthermore, we examine whether independent boards encourage promoters to provide fair reasons for share pledging following a regulation in 2019. Our analysis confirms that independent boards incentivize promoters to provide transparent and justifiable reasons for engaging in share pledging. However, promoters on board reduce this effect.
本文采用平衡面板法,考察了2010 - 2020年印度上市公司控股股东(发起人)的董事会独立性与股权质押行为之间的关系。进一步,我们考察了董事会独立性与发起人作为执行董事在董事会中的存在之间的相互作用及其对发起人股权质押的影响。我们的研究结果表明,独立董事会对发起人的股权承诺起到了威慑作用,特别是当独立董事积极参与时。然而,当发起人在董事会中担任高管职位时,这种威慑作用就会减弱。此外,与商业集团公司不同,董事会独立性未能阻止集中的独立公司的股权质押。此外,我们研究了独立董事会是否鼓励发起人在2019年的监管后提供公平的股票质押理由。我们的分析证实,独立董事会激励发起人为参与股权质押提供透明和合理的理由。然而,董事会的发起人减少了这种影响。

On the basis of green patent transfer data from 41 cities in the Yangtze River Delta (YRD) region and green credit data from five major state-owned banks from 2015 to 2023, this study employs social network analysis and a geographical detector model to examine the spatiotemporal dynamics and systemic coupling between green technology diffusion and green finance development. We document the following key findings: (1) the green technology transfer network has expanded, with Hefei surpassing Shanghai as the core hub, and intensive green technology flows being concentrated in Shanghai, Hangzhou, Suzhou, Nanjing, and Hefei; (2) while green finance has grown substantially, it remains spatially concentrated around Shanghai, leading to a persistent core–periphery divide; (3) the coordination between cities' positions in the technology network and their green finance levels has declined, except in Shanghai, indicating a growing structural mismatch; and (4) factor detection results from the geographical detector indicate that green finance policies act as an independent driving force for the green technology transfer network. Furthermore, interaction detection demonstrates that green finance exerts a stronger influence when it is jointly driven by the urban financial scale and market vitality.
基于2015 - 2023年长三角41个城市绿色专利转移数据和五大国有银行绿色信贷数据,运用社会网络分析和地理探测器模型,研究绿色技术扩散与绿色金融发展的时空动态关系和系统耦合关系。研究发现:(1)绿色技术转移网络不断扩大,合肥超越上海成为核心枢纽,绿色技术密集流动集中在上海、杭州、苏州、南京和合肥;(2)绿色金融虽有较大发展,但空间上仍集中在上海周边,导致核心与边缘分化持续存在;(3)除上海外,各城市在技术网络中的位置与绿色金融水平之间的协调性有所下降,表明结构错配加剧;(4)地理检测器的因子检测结果表明,绿色金融政策对绿色技术转移网络具有独立的驱动作用。交互检测表明,在城市金融规模和市场活力的共同驱动下,绿色金融的影响力更强。

Do managerial pay caps intensify agency conflicts? Evidence from corporate cash holdings 管理层薪酬上限是否加剧了代理冲突?来自公司现金持有量的证据

We leverage the 2015 managerial pay reform in Chinese state-owned enterprises (SOEs) as a quasi-natural experiment to examine whether managerial pay caps intensify corporate agency conflicts. Our results show that affected SOEs opportunistically increase cash holdings, as managers seek to self-compensate for the pay reduction. This cash-hoarding effect is stronger for firms facing more severe agency problems and weaker external oversight. Consequently, firms that hoard more cash due to the pay cap suffer a lower marginal value of cash, decreased operational efficiency, and reduced profitability. Our findings suggest that a “one-size-fits-all” mandatory pay cap may unintentionally exacerbate agency conflicts and hinder economic efficiency.
我们以2015年中国国有企业管理层薪酬改革为准自然实验,考察管理层薪酬上限是否会加剧公司代理冲突。我们的研究结果表明,受影响的国有企业机会主义地增加现金持有量,因为管理者寻求自我补偿薪酬的减少。对于面临更严重的代理问题和更弱的外部监督的公司,这种现金囤积效应更强。因此,由于薪酬上限而囤积更多现金的公司,其现金边际价值较低,运营效率下降,盈利能力下降。我们的研究结果表明,“一刀切”的强制性薪酬上限可能会无意中加剧机构冲突,阻碍经济效率。

This study examines whether strengthened financial regulation can improve resource allocation efficiency and mitigate the labor market monopsony power of superstar firms. Utilizing China's New Asset Management Regulation (NAMR) as a quasi-natural experiment and panel data from Chinese listed firms (2007–2022), we employ a triple difference model to assess the impact of this heightened financial oversight. The results indicate that the regulation significantly curtails the monopsony power of superstar firms, an effect particularly pronounced for those characterized by high labor intensity, substantial R&D investment, and intense market competition. Mechanism analysis reveals that the policy operates by increasing labor input, boosting R&D spending, and improving the human capital structure, which collectively diminish firms' dominance in the labor market. These findings highlight the potential of financial regulation to enhance equity in income distribution.
本研究探讨强化金融监管是否能提高资源配置效率,减轻超级明星企业的劳动力市场垄断权。利用中国资产管理新规(NAMR)作为准自然实验和中国上市公司(2007-2022)的面板数据,我们采用三差模型来评估这种加强的金融监管的影响。结果表明,监管显著削弱了超级明星企业的垄断力量,对劳动强度高、研发投入大、市场竞争激烈的超级明星企业的影响尤为明显。机制分析表明,该政策通过增加劳动力投入、增加研发支出和改善人力资本结构来降低企业在劳动力市场中的主导地位。这些发现突出了金融监管在提高收入分配公平性方面的潜力。

This study examines the impact of corporate headquarters location on firm innovation from the perspective of inventors. Utilizing a sample of Chinese publicly listed firms—a setting characterized by highly concentrated corporate R&D activities and the hukou-related labor frictions—we find that firms located near a higher density of local inventors achieve superior innovation output, as measured by patent counts and forward citations. The positive effect is more pronounced for younger, high-tech firms and those in less developed regions, supporting the local skilled labor supply mechanism. This talent supply also incentivizes firms to reallocate innovation efforts toward exploitative activities and accelerate human capital accumulation. Instrumental variable analysis using the Ming-Qing jinshi density supports a causal interpretation. Our findings provide novel evidence on the value of proximity to specialized human capital and inform policy discussions on mobility constraints.
本研究从发明者的角度考察了公司总部位置对企业创新的影响。我们利用中国上市公司的样本——一个以高度集中的企业研发活动和与户口相关的劳动力摩擦为特征的环境——发现,通过专利数量和前向引用来衡量,位于当地发明家密度较高的公司获得了更好的创新产出。对于较年轻的高科技企业和欠发达地区的企业来说,这种积极效应更为明显,支持了当地熟练劳动力的供应机制。这种人才供应也激励企业将创新努力重新分配给剥削性活动,加速人力资本积累。使用明清进石密度的工具变量分析支持因果解释。我们的研究结果为接近专业化人力资本的价值提供了新的证据,并为有关流动性约束的政策讨论提供了信息。

The resource coopetition effect in family business succession: Successor maturity and corporate risk-taking 家族企业继承中的资源合作效应:继承人成熟度与企业风险承担

Intergenerational succession in family firms raises a basic question: when control passes to the next generation, do firms take more risk, and why? Using a panel of Chinese A-share listed family firms, we develop a composite index of successor maturity—capturing the successor's business capability and willingness to lead—and examine its association with corporate risk-taking. We find that firms led by more mature successors exhibit higher risk-taking. This relation operates through an external relational mechanism: successor maturity is linked to how the firm co-operates and competes with external stakeholders over resources; we proxy these dynamics using supplier and customer concentration. The effect is stronger when financing constraints are weaker and product-market competition is more intense. Overall, our findings suggest that post-succession risk-taking is shaped not only by the successor, but also by the family firm's position in the broader network of resource coopetition in which it is embedded.
家族企业的代际继承提出了一个基本问题:当控制权移交给下一代时,企业是否会承担更大的风险,为什么?我们以中国a股上市家族企业为研究对象,建立了接班人成熟度的综合指数(反映接班人的业务能力和领导意愿),并考察了接班人成熟度与企业风险承担的关系。我们发现,由更成熟的继任者领导的公司表现出更高的冒险精神。这种关系通过外部关系机制起作用:继任者成熟度与企业如何与外部利益相关者就资源进行合作和竞争有关;我们使用供应商和客户集中度来代理这些动态。融资约束越弱,产品市场竞争越激烈,这种效应越强。总体而言,我们的研究结果表明,继承后的风险承担不仅受到继任者的影响,还受到家族企业在其所处的更广泛的资源合作网络中的地位的影响。

Anchoring-induced insider sales in emerging markets: The role of stock price informativeness 新兴市场锚定诱导的内幕交易:股价信息性的作用

Using insider sales data from China's A-share market during 2010–2023, we find that insiders exhibit significant anchoring biases. Insider sales rise when stock prices approach their 52-week high while such trades yield lower profits than those made farther from this point. Anchoring-induced insider sales are more pronounced in stocks with low price informativeness where insiders find it difficult to assess whether their private information has been fully incorporated into stock prices. This behavior is attenuated following earnings announcements, and is also reduced by China's capital market liberalization reforms that enhance stock price informativeness. It is stronger among non-core insiders, who rely more on market signals to evaluate their private information. Beyond selling, the 52-week high also affects insider buying. In addition to the stock-level anchor, the market's 52-week high acts as an anchor in insider selling. Anchoring-induced sales are more pronounced among male insiders but are not significant among insiders with a financial background. Our findings highlight the role of anchoring bias in insider trading and the potential of capital market reforms to curb such behavioral distortions.
利用2010-2023年中国a股市场的内部人销售数据,我们发现内部人表现出显著的锚定偏差。当股价接近52周高点时,内幕交易就会增加,但这类交易的利润低于远离这一点的交易。锚定诱导的内幕交易在价格信息较低的股票中更为明显,因为内部人士很难评估他们的私人信息是否已充分反映在股价中。这种行为在收益公告发布后有所减弱,而且由于中国资本市场自由化改革提高了股价的信息量,这种行为也有所减少。这在非核心内部人士中更为明显,他们更多地依赖市场信号来评估自己的私人信息。除了抛售,52周高点也影响了内部买盘。除了股票水平的锚点外,52周以来的高点也是内幕抛售的锚点。锚定诱导销售在男性内部人员中更为明显,但在具有金融背景的内部人员中不显著。我们的研究结果强调了锚定偏见在内幕交易中的作用,以及资本市场改革遏制这种行为扭曲的潜力。

Economic theory posits that entrepreneurial finance fosters new entrepreneurs, driving technological diffusion and, ultimately, economic development. An efficient financial market influences economic growth through both qualitative and quantitative channels. As a key component of entrepreneurial finance, the primary equity market has been widely recognized for its potential role in promoting economic growth. Yet, the cross-country empirical studies on the role of the primary equity market in economic development remain scarce, largely due to data availability issues and associated methodological challenges in handling complex econometric issues. This study addresses this gap by employing a macro-panel dataset covering 97 countries over 35 years. Using instrumental variable (IV) regressions with five-year averaged data, we find robust evidence that primary equity market development significantly contributes to economic growth. Cointegration analysis using annual data further reveals a long-run cointegrating relationship between the primary equity market and economic growth. The study of short-run deviation around the long-run cointegrating relationship, using the panel-vector error correction model (VECM), confirms significant short-run interactions between the primary equity market and economic growth, while panel-vector autoregression (VAR) tests indicate that causality predominantly runs from the primary equity market to economic growth, rather than vice versa. These findings highlight the importance of primary equity market development as a strategic policy objective for sustaining economic growth. Moreover, findings suggest that firms and portfolio managers can view primary market activity as a forward-looking indicator of future economic performance.
经济理论认为,创业融资会培养新的企业家,推动技术扩散,最终推动经济发展。有效的金融市场通过定性和定量两个渠道影响经济增长。作为创业融资的重要组成部分,一级股权市场在促进经济增长方面的潜在作用已得到广泛认可。然而,关于一级股票市场在经济发展中的作用的跨国实证研究仍然很少,这主要是由于数据可用性问题和处理复杂计量经济学问题时相关的方法挑战。本研究通过采用涵盖97个国家35年的宏观面板数据集来解决这一差距。利用五年平均数据的工具变量(IV)回归,我们发现有力的证据表明,一级股票市场的发展对经济增长有显著贡献。使用年度数据的协整分析进一步揭示了一级股票市场与经济增长之间的长期协整关系。利用面板向量误差修正模型(VECM)对长期协整关系的短期偏差进行了研究,证实了一级股票市场与经济增长之间存在显著的短期相互作用,而面板向量自回归(VAR)检验表明,因果关系主要是从一级股票市场到经济增长,而不是相反。这些发现突出了一级股票市场发展作为维持经济增长的战略政策目标的重要性。此外,研究结果表明,公司和投资组合经理可以将主要市场活动视为未来经济表现的前瞻性指标。
