中国地区金融发展水平的评价与实证分析

从金融发展和经济基础两方面选择了FIR等指标,构建了评价中国地区金融发展水平的评价指标体系,以层次分析法确定指标权重,以阀值法进行无量纲处理,利用所构建的指标体系,对2004年中国31个省市的金融发展水平进行检验。认为,东中西部地区金融发展水平差异明显,金融发展形如一右端被拉长的"橄榄球";东部地区金融发展水平成"圆柱体"形分布;影响西部地区金融发展水平的是"经济短板";制约各省份金融发展的"短板"各不相同。     

商业银行公司金融产品组合营销深化研究

我国商业银行的竞争模式正在从简单的产品扩张向提供深入服务的方向转化，对组合营销这种有效的竞争手段的深化将大大有利于商业银行提升营销层次，提高自身竞争力。作者在总结分析的基础上，提出了公司金融产品进行组合营销深化的基本理念、基本方法和基本策略，以及基于RAROC的组合营销风险考虑方法。本文在分析了阻碍我国商业银行进行组合营销深化的基本因素后，对进一步实施组合营销的深化提出了建议。     

卖空限制对中国权证价格的影响

论文利用中国市场上特有的不允许卖空股票的制度,来实证检验“限制对j中”风险对于权证定价的影响。研究将中国权证市场的定价偏离分解为流动性溢价和动量性溢价（折价）。其中动量性溢价（折价）是市场泡沫的一种体现。研究爱现在权证泡沫出现期间,权证的换手率增高。另外,如果允许卖空,投资者将可以通过套利获取无风险收益。     

Short interest and stock price crash risk

Using a large sample of U.S. public firms, we find robust evidence that short interest is positively related to one-year ahead stock price crash risk. The evidence is consistent with the view that short sellers are able to detect bad news hoarding by managers. Additional findings show that the positive relation between short interest and future crash risk is more salient for firms with weak governance mechanisms, excessive risk-taking behavior, and high information asymmetry between managers and shareholders. Empirical support is provided showing that the relation between short interest and crash risk is driven by bad news hoarding.     

Which financial stocks did short sellers target in the subprime crisis?

Tracing the SEC ban on the short selling of financial stocks in September 2008, this paper investigates whether such selling activity before the 2008 short ban reflected financial companies’ risk exposure in the subprime crisis. Evidence suggests that short sellers sold short stocks that had the greatest asset and insolvency risk exposures, and that the short selling of financial firms’ stocks was not significantly greater than that of non-financial firms after we match them on firm size and insolvency risk. When the short ban was in effect, the market quality of financial stocks without subprime assets exposure had deteriorated to a larger degree than that of financial companies with subprime assets exposure. The findings imply that such a regulation may mute the market disciplining effects of investors and may also be seen as a counterweight to any perceived macro or systemic risk reduction benefits resulting from such a ban.     

卖空限制与收益可预测性——A股融资融券制度的证据

基于A股市场融资和融券余额的巨大差距,本文拓展了Hong et al.(2016)的理论模型,在融券端和融资端分别找到了影响股票收益率的变量:融券比率(融券余额/流通市值)和融资回补天数(融资比率/日均换手率)。进一步,本文利用组合价差法和Fama-MacBeth横截面回归法,实证检验了A股市场中融券比率与融资回补天数解释和预测股票收益率的能力。实证结果表明,在存在融券限制条件下,融券比率相比融券回补天数(融券比率/日均换手率)能更好地代表套利者对股票价格高估程度的看法,根据融券比率构建的等权重多空组合能带来月均1.58%的显著收益;而由于融资约束相对较少,融资回补天数相比融资比率(融资余额/流通市值)能更好地代表套利者对股票价格低估程度的看法,根据融资回补天数构建的等权重多空组合能带来月均1.28%的显著收益。实证结果与本文存在融券数量限制下的理论模型相符,且该收益率不能被多因子模型和常规股票特征所解释。     

Markets for information: Of inefficient firewalls and efficient monopolies

In this paper we study market environments where information is costly to acquire and is also useful to potential competitors. Agents may sell, or buy, reports over the information acquired and choose their trades in the market on the basis of what they learnt. Reports are unverifiable – cheap talk messages – hence the quality of the information transmitted depends on the conflicts of interest faced by the senders. We find that, when information has a prevalent horizontal differentiation component, in equilibrium information is acquired when its costs are not too high and in that case it is also sold, though reports are typically noisy. The market for information is in most cases a monopoly, and there is underinvestment in information acquisition. We also show that regulatory interventions, in the form of firewalls, only make the inefficiency worse. Efficiency can be attained with a monopolist selling differentiated information, provided entry is blocked.     

成品油销售综合经营指标三级预警机制探索--中国石油陕西销售公司的经营实践

2018年以来,中国石油陕西销售公司采用"红橙黄"经营指标三级预警机制,把复杂的量价关系、促销经营和费用成本管控,通过指标量化。一是以经营活动分析为基础,围绕业务指标、财务指标及支撑体系,建立了综合经营指标长效预警机制。二是通过大数据平台,形成业务运行数据每日监控,实现对月度指标的跟踪预警。中国石油陕西销售公司以"红橙黄"经营指标三级预警为抓手,将综合指标评价理念贯穿到经营全过程中,为生产经营活动提供了直观的决策依据,实现了提质增效的目标。     

高效的营销系统模型在竞争市场环境中的理论应用

目前绝大多数营销活动的预测都只能定性的做一些粗略的估计，还不能做到定量分析与管理，这给正确的销售规划带来了困难。本文根据市场运行的规律分析一个销售方和竞争对手的销量函数关系，指出影响销量的因素分为三类：市场因素、本方因素、对手因素，对连续型的数量关系用解微分方程组的方法推导出结论．对离散型数据关系也类推出数学表达式。给出了来源于实际的两个例子。该数学模型的特点是构造市场运动的结构关系，不需要大量的统计数据，简洁实用，可操作性强，准确性高，适应性强。从而为理论界以及销售管理者实施管理提供了一个定量、合理、高效的管理工具。     

关于浙江实行粮食购销市场化的思考

国务院决定浙江从2001年起取消粮食定购,实行粮食购销市场化,这是促进浙江经济发展的一项重大的战略决策。本文从浙江省粮食流通体制改革的发展入手,分析了浙江实行粮食购销市场化的必然性及其主要障碍,参照国内外粮食流通的基本做法,提出从省情出发,建立符合社会主义市场经济要求的粮食经济制度的政策选择。
