• 详情 科技赋能提升了金融支持实体经济的效率吗? —基于金融供求结构的视角
    在深化金融供给侧结构性改革,建设数字中国的背景下,金融科技赋能金融机构对释放实体经济发展活力,推动金融体系脱虚向实具有重要意义。本文采用2011-2020年31个省、区、市的面板数据,实证检验金融科技对金融支持实体经济及不同实体行业效率的影响,并基于中国银保监会官网金融许可证信息爬取的258772条金融机构数据,结合4998家上市公司的数据构建金融供求结构指标,从金融供求结构的视角考察金融科技脱虚向实的影响渠道。研究发现,金融科技推动了金融支持实体经济效率的提升,对金融支持第三产业效率的影响较为明显,各种稳健检验均支持这一结果。在金融供给端,金融科技从增强金融机构竞争程度、提升地方性金融机构发展水平、缓解资源错配三个维度优化金融供给结构;在金融需求端,金融科技通过增强企业贷款可得性、深化实体行业与金融业关联程度改善金融需求结构,从而提升金融支持实体经济的效率。最后,金融科技的脱虚向实作用在对外开放水平低、金融机构网点数量较少和创新水平较低的地区更为显著。本文的研究揭示,金融科技的应用为增强金融服务实体经济的能力,改善金融供给结构的不平衡提供了契机。
  • 详情 数字经济提升了绿色创新效率吗?——来自中国城市的经验证据
    本文通过测度2011-2019年中国282个地级市的数字经济和绿色创新效率水平,探讨了数字经济提升中国城市绿色创新效率的效应及机制。通过指标替换和不同计量方法进行稳健性检验,同时使用各城市与杭州的球面距离和数字经济词频作为工具变量进行内生性检验。从优化产业结构、促进人力资本高级化两个角度,检验数字经济提升城市绿色创新效率的具体机制。研究发现,数字经济显著提升了城市绿色创新效率,该结论在引入工具变量进行稳定性检验后仍然成立。作用机制的研究显示,优化产业结构和促进人力资本高级化是数字经济提升城市绿色创新效率的重要传导路径。最后,本文从区域分布、城市资源差异、城市层级三个方面进行分析,研究发现数字经济发展对城市绿色创新效率的影响效应具有异质性。本文的研究对发挥数字经济的绿色价值、改善资源配置、深化认识数字经济的低碳价值和兼容反哺效能、促进经济绿色高质量发展具有重要意义。
  • 详情 Leaving a legacy for my children: The one-child policy reform and engagement in CSR among family firms in China
    The reform of China’s one-child policy allows families to have more children and thus may affect anticipation of intergenerational succession of family businesses and drive family firms to improve their corporate social responsibility (CSR). Using a difference-in-differences design, we find that the reform positively affects family firm CSR. We also find that the positive impact is more pronounced for family firms whose owners have fewer children, have no son, and are of reproductive age, which confirms the theory that intergenerational succession anticipation drives family firm CSR. Moreover, we find that the positive impact is more pronounced for firms that operate in environments where CSR is more strategically important. We validate our findings by showing that the reform curtails family firms’ short-termism.
  • 详情 中国商业银行绿色债券发行动机实证研究 ——基于监管套利的视角
    本文从监管套利的角度对中国商业银行发行绿色债券的动机进行实证研究。控制了样本选择偏差和内生性影响后我们发现,流动性越差的商业银行越有可能通过发行绿色债券融资。此外,门限回归的分析结果表明,资本充足率对于商业银行发行绿色债券的数量存在某一“门槛效应”,当商业银行的资本充足率低于该“门槛”时,商业银行发行绿债的数量不受其流动性状况的影响,但当资本充足路高于该“门槛”时,商业银行发行绿债的数量与其流动性有显著的负相关关系。实证结果表明,流动性差的中国商业银行更愿意承担更高的绿债发行成本进行融资。市场现状显示,中国绿色债券市场的政策环境为商业银行的监管套利提供了空间。本文的结论为监管部门改进绿色债券的发行政策提供了重要的理论依据。
  • 详情 对投资信息处理中代表性偏差对投资决策的影响研究
    代表性偏差由著名心理学家Kahneman和Tversky提出,指人们于根据观察到的某种事物的模式与其经验中该事物所形成典型模式的相似程度而进行判断。某一事物与其类别高度相似,则其代表性越高。这种情况在人们的金融投资活动中往往扮演着重要角色和作用。因此研究这种偏差对投资心理活动对信息处理加工输出的不同阶段的影响,对投资者对金融市场的投资决策往往会起到一定的重要辅助作用。
  • 详情 地区腐败、融资约束与慈善捐赠
    基于2003-2015年沪深A股非金融行业上市公司的数据,本文考察了地区腐败与该地企业慈善捐赠的关系,以及融资约束对上述关系的影响。研究发现,地区腐败越严重,该地企业的慈善捐赠会越少,呈现地区腐败的慈善抑制效应。公司的融资约束会加剧地区腐败的慈善抑制效应。即,在腐败严重地区,融资约束越严重的公司慈善捐赠会越少。数学模型的推导结果表明,地区腐败与慈善捐赠之间的负向关系源于行贿对慈善捐赠的挤出效应。即,在腐败严重地区,与慈善捐赠相比,直接行贿更有利于公司实现利润最大化的目标。从而,理性的公司会选择行贿,而非慈善捐赠。强力反腐会削弱地区腐败的慈善抑制效应。这与强力反腐提高了公司行贿的成本密切相关。该研究不仅从理论上揭示了地区腐败、融资约束与慈善捐赠之间的内在逻辑关系,还为我国优化商业道德,推进反腐进程,维护市场秩序提供了理论依据。
  • 详情 房地产价格与居民消费 ——基于蚂蚁金服抽样用户的实证分析
    近年来,一方面,我国消费不足的问题长期存在,另一方面,房地产价格整体上升。那么,房价将如何影响了居民消费?利用蚂蚁金服2017年1月到2019年4月100万抽样用户的淘宝消费与“中国百城房价”数据,本文考察了房价对居民消费的作用。研究发现,第一,房价的上升对消费有抑制作用,且导致了消费降级;第二,流动性约束较高的用户,房价对消费的负向影响更高;第三,上述效应具有异质性,房价对消费的抑制作用主要作用于享受型消费、对收入较低的群体更加显著、且主要体现在三线及以下城市。以上结论在多种检验下保持稳健。本文提示了房地产价格过快上涨的风险,以及缓解居民流动性约束的重要意义。
  • 详情 Public Data Access and Stock Price Synchronicity: Evidence From China
    Using the staggered opening of governmental public data platforms in China, we employ the difference-in-difference approach to investigate how public data access affects stock price synchronicity. We find that stock price synchronicity significantly drops after the public data platform is established in a firm’s headquarters city. The underlying mechanism is reducing information acquisition costs rather than increasing market attention or corporate information disclosure quality. Furthermore, the informational role of public data platforms magnifies under higher informed trade risk, poorer corporate governance, or better regional economic and innovation capacity. We highlight the role of public data in facilitating financial market efficiency.
  • 详情 National Industrial Investment Fund and Corporate R&D Investment: Evidence from China
    Using the establishment of the Chinese Integrated Circuit Industry Investment Fund in 2014 as a quasi-natural experiment, we investigate whether and how the national industrial investment fund affects corporate R&D investment. We find that the policy has a significant and positive effect on corporate R&D investment, and this effect is more pronounced in firms with more severe financial constraints, poorer internal governance, and laxer external supervision. Furthermore, the mechanism tests show that this policy helps alleviate firms’ financial constraints and agency conflict, thereby increasing corporate R&D investment.
  • 详情 Labor Protection and Financing Decisions of Firms: The Case of China
    Serfling (2016) examines how the increase in firing costs impacts the capital structure decisions of firms and hypothesizes that higher firing costs of labor lead to a decline in a firm’s financial leverage use by directly increasing its distress costs and indirectly lifting its operating leverage. Stricter labor protection laws passed in China in 2007 provide an opportunity to revisit the issue within a controlled environment. Employees of SOEs already enjoy the benefits that the new labor law imparts. So, SOEs are exposed to lower firing costs than their non-SOE counterparts. Additionally, the exposure to bankruptcy is more limited for SOEs than non-SOEs. We hypothesize and show that non-SOE firms’ financial leverage decreases more than SOEs, confirming the leverage-lowering effect of labor protection laws. Further, the decline in financial leverage is more pronounced for a labor-intensive firm or one that encounters steep competition.
