境外资本市场股价定位的定性分析

本栏文章代表作者个人观点，仅供参考亚洲金融危机以来，我国在境外上市的 43支股票价格持续低迷，在香港上市的三支电力股票 (大唐发电，山东国际电源，华能国际 )同样在动荡中起伏。而同是电力股的 A股电力板块却整体看好。究其原因除资本流通的环境不同外，境外成熟的资本市场对股票价格的定位迥异于国内资本市场是主要原因。境外资本市场对股价定位一般遵循以下原则：一、高成长性是决定市场定价的客观依据对于上市公司而言，有没有持续的增长是股票发行成功与否的关键所在。投资者期望的是以现时的有一定折让的现值，购买公司未来的成…     

异质机构投资者、 企业性质与科技创新

本文以我国沪深两地762家2012～2017连续5年A股上市公司的数据为样本，运用平衡面板固定效应模型实证研究了压力抵抗型机构投资者与压力敏感型机构投资者对企业研发投入的影响。结果显示，机构投资者整体可以在一定程度上提升企业创新投入水平；压力抵抗型机构投资持股比例的增加可以促进企业科技创新；压力敏感型投资者对企业创新水平无显著影响。且在不同性质的公司中，机构投资者对企业科技创新的治理效果存在一定的差异，机构投资者在非国有控股企业及高新技术行业企业中的治理效果更加明显，研究结论为促进机构投资者参与公司治理、推动资本市场健康发展提供了新的依据。     

沪港两地新股情况分析

运用均值比较与方差分析,发现沪市股票市场化程度远低于港股,集中体现在发行价、初始收益率及中签率等方面.根据完全竞争市场理论,建议:尽量减少中间环节,消除承销商等中间环节,建立上市公司与投资者直接对话与沟通的新股定价与发行机制.     

B股政策破冰前的3大猜想

在中国资本市场的版图设计里，B股（人民币特种股票）市场绝对只能算得上是一只“丑小鸭”。区区109家上市公司，区区百亿股的市值规模，如果有谁胆敢把这样一个袖珍市场和枝繁叶茂的A股市场、H股市场相提并论的话，那可真是滑天下之大稽!     

现金股利的治理效应:基于企业成长性视角

现金股利的发放,对维护中小投资者的利益和保持资本市场的可持续发展有着重要意义。本文以2008-2011年间沪深两市A股上市公司为研究样本,从企业成长性出发,考察代理成本对现金股利的影响。研究发现,发放现金股利可以缓解代理成本,企业成长性是通过影响自由现金流对现金股利的发放产生影响。     

制造业上市公司资本结构研究——以安徽省为例

在考查安徽省36家A股制造业上市公司2006～2010年资本结构现状的基础上,实证研究其资本结构的影响因素及与经营绩效的互动关系。研究表明,影响安徽省制造业上市公司资本结构的因素主要有公司规模、盈利能力、经营能力、成长能力、股权集中度;股权资本约束力不足、股权融资偏好以及资本市场结构失衡导致其资本结构与经营绩效之间无显著相关性。为此,提出优化安徽省制造业上市公司资本结构的对策建议。     

收益率差异视角下股票流动性与资本结构关系的再检验

本文在股票收益率差异视角下，选择2000年1月到2015年12月期间中国沪、深市场307家上市公司数据，采用单方程估计法和联立方程组系统估计法研究我国上市公司股票流动性与资本结构的相互影响；并分别从股权分置改革、股权再融资、牛熊市行情三个方面对二者关系的变化与差异进行深入分析。结果表明：股票流动性与资本结构之间存在显著的负向关系，并且随着股票收益率水平的提高，负向影响越来越明显；股权分置改革后、满足再融资资格的上市公司以及牛市行情下两者的相互影响更显著。     

A股无回报？——A股无回报？

世界上从未有一个资本市场像A股市场一样，肩负如此多的重任：为国企解困、为国有银行减压、为创新型企业输血，在此导向下，资本市场的融资功能发挥到了极致，上市公司也依靠资产证券化迅速膨胀。然而，为维持一个资本生念正常循环所应尽的基本义务——回报投资者却长期被忽略，A股陷入了一个“涸泽而渔”的危险境地。     

中国公司的华尔街之旅

今天的中国概念股,往往与A股联动,在上演出波澜壮阔的行情之余,同样,一些中国概念股上市公司之中也有害群之马,也把一些损害股东权益的做法带到了美股市场。有一批中国概念股票,就是因为公司管治出现问题,遭到股东的抛弃     

煤炭企业改制上市应注意的问题

一、慎重对待改制上市工作1.合理确定上市方式.根据国有煤炭企业的特点,可以采取两种方式进入资本市场.①新组建股份公司,通过新股发行直接上市.目前,我国证券市场上的绝大多数企业包括煤炭上市公司都是通过这种方式进入证券市场的.这种方式适用于规模比较大,已保持了较好盈利水平的企业.从目前的股票种类看,国有煤炭企业可选择的股票种类主要有:A股、B股、H股、N股和即将开设的创业板.     

基于ESDA方法与空间计量模型的房价溢出效应分析

一个地区房价的波动可以通过时间滞后传递到其他地区，从而产生房价溢出效应。本文以我国31个省际区域2005～2014年的数据为样本，运用探索性空间数据分析（ESDA）对31个省的房价空间分布格局及演变态势进行分析。然后运用空间计量模型分析我国省际房价变动的影响因素，并从地理因素和经济因素两个方面研究房价溢出效应。研究结果表明：中国31个省域间的房价存在明显的空间相关性；地区的城市化率、城镇就业人员平均货币工资、二、三产业产值占GDP比重对房价有显著的影响，房价存在显著的空间溢出效应，经济距离对地区房价影响比地理距离的影响更显著。     

Rethinking shipments asymmetries

A modification of a well-known shipments test for geographic market definition may be useful in identifying antitrust markets. By recognizing the possible significance of a high LIFO value and a notably lower LOFI value, and searching for possible barriers to product entry that could explain the asymmetry, analysts can reduce the chances of adopting an overly broad geographic market. This is illustrated by comparing the results from applying the shipments test to those from residual demand estimations, and by reviewing the evidence and findings in several recent antitrust proceedings in light of the asymmetric shipments patterns they report.     

Predatory Lending Laws and the Cost of Credit

Various states and other local jurisdictions have enacted laws intending to reduce predatory and abusive lending in the subprime mortgage market. These laws have created substantial geographic variation in the regulation of mortgage credit. This article examines whether these laws are associated with a higher or lower cost of credit. Empirical results indicate that the laws are associated with at most a modest increase in cost. However, the impact depends on the product type. In particular, loans with fixed (adjustable) rates are associated with a modest increase (decrease) in cost.     

区域创新系统绿色创新效率的空间分布及收敛性研究

本文运用Super-SBM-Windows效率评价方法对2005～2014年我国区域创新系统绿色创新效率进行了评价，利用ESDA方法深入分析了我国区域创新系统绿色创新效率的空间分布特征，同时采用空间误差面板模型检验其收敛性。研究表明：①我国区域创新系统绿色创新效率呈现从东部、中部到西部由高到低的阶梯式发展格局，绝大部分区域创新系统绿色创新效率呈逐年增长趋势，而且各省级之间的绿色创新效率差异程度在逐渐缩小；②我国区域创新系统绿色创新效率在空间分布上存在明显的空间聚集效应，这种聚集效应主要表现在低值区域，而高值区域的辐射带动作用还很有限；③我国区域创新系统绿色创新效率存在明显的绝对β收敛趋势。     

Spillovers in Space: Does Geography Matter?

Using U.S. firm level panel data we simultaneously assess the contributions to productivity of three potential sources of research and development spillovers: geographic, technological, and product market (“horizontal”). To do so, we construct new measures of geographic proximity based on the distribution of a firm's inventor locations as well as its headquarters. We find that geographic location is important for productivity, as are technology (but not product) spillovers, and that both intra and inter–regional (counties) spillovers matter. The geographic location of a firm's researchers is more important than its headquarters. These benefits may be the reason why local policy makers compete so hard for the location of local R&D labs and high tech workers.     

Multilevel governance and broadband infrastructure development: Evidence from Canada

This paper investigates the contributions of digital infrastructure policies of provincial governments in Canada to the development of broadband networks. Using measurements of broadband network speeds between 2007 and 2011, the paper analyzes potential causes for observed differences in network performance growth across the provinces, including geography, Internet use intensity, platform competition, and provincial broadband policies. The analysis suggests provincial policies that employed public sector procurement power to open access to essential facilities and channeled public investments in Internet backbone infrastructure were associated with the emergence of relatively high quality broadband networks. However, a weak essential facilities regime and regulatory barriers to entry at the national level limit the scope for decentralized policy solutions.     

Why strategic factor markets matter: “New” multinationals' geographic diversification and firm profitability

This study examines firm profitability differences among “new” multinational enterprises (NMNEs) pursuing geographic diversification into two distinct types of geographic locations based on the development of strategic factor markets. Building on strategic factor markets theory, we propose that firm‐specific advantages of NMNEs contribute differentially to firm profitability because they evolve differently given strategic factor market differences in host compared to home countries. Using a sample of Korean manufacturing MNEs during the 1993–2003 period, we find that geographic diversification into resource‐poorer host countries has a positive relationship with firm profitability, whereas geographic diversification into resource‐richer host countries has a U‐shaped relationship with firm profitability. Our study demonstrates why strategic factor markets—an important and often overlooked contextual factor—matter in exploring rationales for geographic diversification.

Public- and Private-Sector Wage Differentials in Canada Revisited

Using a variety of techniques, we estimate the wage premium for federal, provincial, and municipal public-sector employees in Canada. We find that females in the public sector are paid a wage premium, with federal government workers enjoying the highest rents, followed by local and provincial public-sector employees. Estimates for males suggest that rent payments are comparably less, but results are inconclusive.     

Discriminatory Dealing with Downstream Competitors: Evidence from the Cellular Industry

One concern about regulated monopolies entering unregulated vertically-related markets is that they will discriminate against competitors of their unregulated affiliates. However, prohibiting regulated monopolies from offering related goods may preclude production by the most efficient provider. We take advantage of variation across geographic cellular phone markets in the US to examine the effect of integration on output, quality and prices. We find some evidence consistent with efficiencies (greater concentration of lines to users is associated with greater output and higher quality) and some consistent with discrimination (greater interconnection facility ownership concentration is associated with lower output and quality).
