Description中医药是中华文明的瑰宝，中药材是中医药文化和产业的核心。随着近年来国家相关政策出台，中药材产业的发展备受瞩目。由于中药材产业链条长，层级多，各层级间信息不对称，因而中药材市场普遍具有“假”、“乱”、“杂”的问题。
A公司的中药材全产业链服务商模式，通过对上游各主要专营商的整合，形成一定的平台综合集采能力，并开始得到下游医药厂家、药店认可，在市场逐步形成品牌号召力。本文实证研究A公司商业模式的转型对中药材市场价格的影响，进而分析中药材全产业链服务商模式在中药材行业健康发展中所发挥的积极作用。研究结果表明，上下游产销结合的中药材全产业链服务商模式，只有在形成一定收购规模，对市场价格产生一定影响的时候，才能充分释放药材质量的信号，润滑药材交易市场，提高收购价格，增加市场波动率，发挥价格发现作用。由于中药材市场的信息不对称程度较高，如果产销结合模式仍处于初级开创阶段，产销结合模式释放的药材质量信号则不足以全面改善信息不对称的状况。

Description中国证券市场一直存在着双重上市公司A、H股价差异现象，这一“同股同权不同价”的现象，长期以来都是国内外学者热议的课题之一。
本文在系统性整理前人研究成果基础上，首先对造成A、H股价差效应的内在逻辑进行了系统梳理，提炼出影响双重上市公司A、H股价格差异的9个潜在因素：信息不对称、需求差异、流动性差异、投机性差异、风险差异、公司治理结构、利率差异、市场强弱差异、汇率预期。其次，本文为各潜在影响因素构建了新的代理变量，建立面板数据模型，从全市场和行业两大视角做了实证分析，验证了影响双重上市公司A、H股价格差异的可能因素，且实证结果均通过了平稳性检验。实证结果显示：全市场视角下，仅公司治理结构和市场强弱差异对A、H价格差异的影响不显著。行业视角下，对于金融行业的双重上市公司而言，影响其A、H股价格差异的因素包括：需求差异、流动性差异、风险差异、市场强弱差异、利率差异；信息不对称、投机性差异、公司治理结构、汇率预期不具有显著影响。而对于非金融行业的双重上市公司而言，影响其A、H股价格差异的因素包括：信息不对称、需求差异、流动性差异、风险差异、投机性差异、市场强弱差异、利率差异、汇率预期；公司治理结构则不是显著的影响因素。
本文在实证分析所得结论的基础上，考虑到当前A、H股市场的现状，提出了加强资本市场双向开放、大力发展以基金为代表的机构投资者、坚定推行股票发行注册制改革、推动金融创新、丰富投资工具等建议。这一研究结果对于推动我国资本市场进一步完善，具有重要的理论与现实意义。

Description
During the past decade, the Chinese bond market has been rapidly developing. The percentage of bond to total social funding is constantly increasing. The structure and behavior of investors are crucial to the construction of China’s bond market. Due to specific credit risks, bond market regulation usually involves in rules to control investor adequancy. It is heatedly discussed among academia and regulators about whether individual investors are adequate to directly participate in bond trading. This paper focuses on the comparison between individual and institutional bond investors, especially their returns and risks. Based on the comparison, this paper provides constructive suggestions for China’s bond market development and the bond market investor structure.

Shareholder Activism is a mechanism by which investors who hold a significant but
non-majority percentage of a company’s stock, exercise their voting rights, participate in
corporate governance and influence operational decisions of target companies. The
purpose is improve corporate governance, increase firm performance and boost share
-holders’ returns. Existing studies of shareholder activism, based largely in mature
capital markets like the US, come to different conclusions regarding its impact on firm
performance.
In this paper, I collect data on shareholder activism events in the China A Share
market between 2006 and 2016. The sample includes 60 companies targeted by 42
activist investors over this period. I find that institutional investors, typically industrial
capital and private funds, playing an increasingly important role in corporate governance
of Chinese listed companies through activism. The disclosure of the holdings of activists
results in large gains in the target firm. I also find subsequent improvements in long
-term operational performance of target firms. Activist investors in China focus on
smaller targets and those characterized by higher agency costs and lower operating
performance. Activists appear to be largely concerned with improvements in business
strategy and M&A activity. Non-hostile behavior is more likely to be related to successful
activism in China. In addition to statistical evidence, I present case studies of the
“BaoWan dispute” and the activist investment of Butterfly Capital in two firms,
“Guonong” and “Xiuqiang”. The case studies highlight the mechanism employed by these
firms to influence performance.
I conclude with policy recommendations and direction for further research.

Description
Since the 2008 financial crisis, the total assets managed by U.S. mutual funds have frequently hit new highs and the industry has become increasingly concentrated. In the meantime, two strategies have emerged in the American mutual fund industry: active and passive management. What factors affect the market shares of firms that adopted these two different strategies?
Building on strategic management theories, I suggest that mutual fund families that adopted active and passive management strategies tend to compete in different dimensions. Active management fund families tend to implement the product differentiation strategy, competing on “product quality” through excess-returns, innovative and differentiated fund products; passively managed fund families focus more on "price competition" by conducting an overall cost leadership strategy.
This research examines the driven factors of fund families’ market share. The results show that: the market share of actively managed fund families is more sensitive to positive impact of fund performance, while passive management firms are more sensitive to negative effect of management fees and total loads; 12b-1 expense improves the competitiveness of active fund families and thus enhance their market shares but it has negative impact on passive fund families. In addition, high turnover decreases the market share of all fund families, especially for passively managed families. The outcome reveals the latest US mutual industry orientation: products differentiation, turnover, management fee have greater impact on market share while the competition of fund performance is diminishing. The Matthew effect in US mutual fund industry is outstanding. Industrial competition dimension expands from performance and products to cost cutting.
Empirical analysis on Chinese mutual fund families is also conducted. Different from the US, there is only small number of mutual fund families targeting passive management products. The results show that the distribution channel has the largest impact on Chinese mutual fund family market share and investors are more willing to chase performance than to consider cost-efficient fund families. This study then analyses reasons behind the difference of Chinese and American mutual fund industries.

Description期限错配策略利用滚动短期融资支持长期投资，滚动短期融资本身极易导致资金链紧张，产生流动性风险。利用手工收集的2006-2018年A股上市公司独特数据，本文系统考察了企业投融资期限错配对发行信用债信用利差的影响。本文发现，期限错配越严重的企业，越有可能在发行信用债时被要求更高的信用利差，对于民营上市公司发行信用债尤其如此；利用再融资环境和“钱荒”事件进行的作用机制检验表明，企业投融资期限错配对发行信用债利差的影响主要是因为期限错配蕴含着较高的流动性风险； 利用工具变量、双重差分法和替代性度量等一系列稳健性检验仍能得出一致结论。再者，利用2006-2018 年我国开放式基金年度持股数据，从基金投资组合与持仓调整两个角度，实证检验了期限错配行为对于基金投资行为的影响。研究发现，期限错配产生的财务风险会降低基金对期限错配上市公司发行信用债的投资规模；且在实施期限错配当年，基金对持有的该上市公司的信用债更可能进行减持，由此表明期限错配会影响基金投资策略的形成。进一步的分析显示，基金所在基金管理公司为中外合资时，上述基金投资行为更加明显；同时，当基金持有民营上市公司以及处于紧缩性货币政策环境时，期限错配对于基金投资行为的影响更大。
最后，本文考察了期限错配下基金投资信用债的经济后果，分别从基金业绩、基金收益波动率和基金流量这三个维度进行了检验。实证结果显示，在控制其他可能影响基金收益及收益波动率的因素后，对期限错配上市公司信用债持有比重越小及减持比例越大的基金，当年业绩越好，且收益的波动率越低。再次，对于基金投资者，本文利用净申购率作为基金流量的代理变量，检验发现，基金投资者更热忠于追逐采取减少持有期限错配上市公司信用债这一投资策略的基金，表现为这类基金有更多的资金净流入，而且，相对于个人投资者，上述基金投资者的投资偏好在我国的机构投资者中表现得更加明显。

Description本文对不良资产法拍定价的实践操作进行分析，选取一线、二线部分城市的住宅为主要研究对象，以主流互联网拍卖平台上真实成交的司法拍卖案例为样本，样本覆盖上海、杭州、苏州、南京等国内一二线城市主流司法拍卖资产，时间跨度为2017年至2020年。本文选取影响不良法拍资产定价的主要因素有：资产面积、位置、税费承担方式、参拍人数、加价轮数、租约情况等，以上述主要因素为自变量因素，以不良法拍资产价格偏离指数及参拍人数作为因变量。回归模型分别采用线性回归和二阶段最小二乘法，把资产面积、位置、税费承担方式、参拍人数、加价轮数、租约情况作为核心变量，研究各个因素对于不良资产拍卖成交价格的影响程度。本次所采用的回归分析中，由于研究的因果关系涉及因变量和两个以上自变量，因此在研究过程中选取六个核心变量，在系统梳理大量样本数据的基础上，利用数理统计方法建立因变量与自变量之间的回归模型，通过线性回归方法研究六个核心变量与因变量之间的关系，并通过二阶段最小二乘法来剔除核心区域、税费承担方式、租约情况对参拍人数的影响，最终得出核心变量对因变量的影响。经研究发现，位置、资产面积、税费承担方式、租约情况对△p呈负向影响，参拍人数、加价轮数对△p呈正向影响。
