金融发展影响城乡收入差距的三大效应分析及其检验

金融发展影响城乡收入差距主要通过三条途径，即金融发展的门槛效应、金融发展的降低贫困效应、金融发展的非均衡效应。本文利用中国和省级1978-2004年的相关数据进行实证检验，结果显示实证与理论假说相符。最后，提出了相关政策建议。     

上市公司募资变更公告财富效应的实证研究

文章采用事件研究法对2002年～2008年募资变更公告的财富效应进行了实证研究。研究结果表明,我国上市公司募资变更公告在（-10,＋10）期间产生了财富效应,在整体上增加了股东财富。通过多元线性回归分析,进一步发现募资变更公告的财富效应与资产负债率正相关,与第一大股东持股比例负相关。     

校友关系负外部性治理效应提升研究

基于上市公司高管与独立董事的校友关系，选取2008～2020年沪深A股上市公司为研究对象，检验股吧网民对该校友关系负外部性的舆论监督效应，及其引致证券交易所问询函监管的运行机制和作用特征。研究发现：股吧网民监督与校友关系负外部性显著负相关；股吧网民监督对校友关系负外部性不仅具有显著的抑制作用，而且能够引致证券交易所问询函监管，提升交易所一线监管效率，实现融合数字化平台和股吧网民、监管部门等多元参与的数字治理微观效应。机制检验发现：虽然校友关系隐蔽性极强，但股吧网民能够借助公司股价变动趋势识别其真实盈余管理行为，股价同步性发挥了完全中介效应。     

人民币实际汇率变动的出口贸易效应研究

基于跨期最优化贸易模型,通过引入外部不确定性,分析了实际汇率对出口贸易的影响。研究表明:如果企业生产规模报酬递减,则实际汇率变动率增大将导致企业出口量及利润增加。运用中国1985年-2008年间相关数据进行实证检验,发现人民币实际汇率与出口呈正向关系,马歇尔-勒纳假说在中国成立。     

金融错配对宏观经济下行风险存在异质性冲击吗?——基于规模效应与效率效应的维度

近年来随着我国宏观经济下行压力的不断加大，金融错配是否对宏观经济下行风险构成异质性冲击成为需要重点关注的问题。在阐释金融错配规模效应和效率效应引致宏观经济下行风险逻辑机理的基础上，以2005—2019年数据为样本实证分析了金融错配规模效应和效率效应对宏观经济下行风险的异质性影响。实证结果表明，随着对外开放和金融体系改革，我国金融资源配置中的所有制歧视已得到有效缓解，金融错配的效率效应显著改善。然而，由于规模效应在风险链条传导过程中的累积反馈，规模歧视已成为引发宏观经济下行风险的主渠道。这些研究结果为构建金融支持实体经济的政策框架和防范化解宏观经济下行风险提供了有益启示。     

上海股票市场规模效应的实证研究

规模效应是指公司规模与收益率之间存在的反向关系,即小规模公司较大公司而言有着更高的收益率。本文从上海证券市场随机抽取60只股票作为数据样本,对其从2007年1月到2009年6月之间的公司数据进行实证研究,得出上海股市存在着规模效应这一结论。     

国有股权参股与民营重污染企业绿色治理

由于生态环境投入的外部性和资本的逐利性,民营重污染企业的绿色治理是我国企业绿色治理的重点和难点.本文分析了国有股权参股对民营重污染企业绿色治理的影响机理,并以2008～2019年A股上市的民营重污染企业为研究样本进行了实证检验.研究发现,国有股权参股能够通过治理效应和资源效应促进民营重污染企业绿色治理;相对于污染风险较...     

垄断平台的开放性策略研究

通过建立模型,并将负的组内网络外部性及正的组间网络外部性引入到模型中,研究垄断平台的开放性策略选择。研究结果表明,当销售的规模经济效应所节约的成本与较强的商家之间负的组内网络外部性效应的叠加超出了单边模式下所有商家所损失的、消费者带给商家的正组间网络外部性效应时,平台将会选择更为封闭的单边模式;当商家与消费者之间正的组间网络外部性效应较大,且商家之间负的组内网络外部性效应较小,同时也不存在销售的规模经济效应时,平台将会选择更为开放的双边模式。     

关于场外衍生品的企业价值效应研究——基于我国上市银行的面板数据模型分析

随着市场经济与金融创新的不断深化,我国场外衍生品市场得到了迅猛的发展,而商业银行正是这一市场的主要参与者。文章以我国上市银行为研究样本,利用2006年-2012年的半年度数据进行实证分析,发现银行使用场外衍生品对企业价值产生了正效应。然而由于存在各种外部条件的制约,这种正效应并不显著。研究还表明,我国银行使用场外衍生品存在规模经济和范围经济。     

规模效应和价值效应的再检验——来自中国沪市的经验证据

资本资产定价模型(CAPM)自产生以来,经历了无数的实证检验.实证研究发现了与CAPM理论相左的现象--市场存在异常收益(Anomalies).本文针对异常收益现象,研究了2001～2003年间中国证券市场中托宾Q、规模、市盈率与公司绩效的关系.检验结果显示,在我国沪市,公司规模基本不影响公司绩效,市盈率对公司绩效存在较弱的影响,托宾Q对公司绩效有较显著的影响,即我国股市不存在规模效应,存在E/P效应和显著的托宾Q效应.     

我国综合交通运输网络发展回顾

回顾了30年(1978-2008)来我国综合运输网络规模与布局,并对比分析了五种交通运输方式的指标,对我国综合交通运输网络现状进行了分析。     

The impact of funding liquidity on market quality

This study analyzes market quality during the 2007–2008 credit crunch, by examining the impact of funding liquidity on market liquidity and price discovery of S&P 500 exchange-traded funds (i.e., S&P 500 depositary receipts [SPYs]) and index futures (E-minis). The empirical results show that funding liquidity affects market liquidity, and that the impact of illiquidity contagion between SPYs and E-minis was significant during the subprime mortgage crisis. In particular, the contagion effects between the two markets mediate the impact of funding illiquidity on market liquidity during the credit crunch. Considering the influences of other market factors on price discovery, we suggest that E-mini index futures made less contributions to price discovery during the credit crunch compared to normal periods. The empirical finding emphasizes the importance of the contagion effect between ETF and E-mini futures markets, when they suffer from external shocks.     

The puzzling effects of monetary policy in VARs: Invalid identification or missing information?

Standard vector autoregressions (VARs) often find puzzling effects of monetary policy shocks. Is this due to an invalid (recursive) identification scheme, or because the underlying small‐scale VAR neglects important information? I employ factor methods and external instruments to answer this question and provide evidence that the root cause is missing information. In particular, while a recursively identified dynamic factor model yields conventional monetary policy effects across the board, a small‐scale VAR identified via external instruments does not. Importantly, the discrepancy between both models largely disappears once the information set of the VAR is augmented via factors. This finding is comforting news for the recent monetary literature. Two leading empirical advances with different underlying assumptions—namely external instruments (applied to a factor‐augmented VAR) and dynamic factor models (identified recursively)—find very similar effects of monetary policy shocks, cross‐verifying each other.

基于产业规模探索区位基尼系数的简化计算、区域分解和两位数产业分解,给出产业份额、区位商以及产业份额空间测度加权区位基尼系数的分解公式,提供相对边际效应和增量分解的计算公式。利用我国2004年、2008年的经济普查数据,计算国民经济19个字母产业的区位基尼系数,得出以产业份额计算的区位基尼系数更能反映产业聚集程度的结论,并使用产业份额区位基尼系数进行实证分析。     

A multiproduct Symmetric Generalized McFadden cost function

This paper introduces a flexible multiproduct cost function that permits zero values of one or more of the outputs and can impose restrictions quite easily, if not automatically satisfied, to ensure global concavity property. It satisfies linear homogeneity (in prices) property and is flexible in the output space. Thus the function is ideal for estimating, for example, economies of scope, cost complementarity, product-specific returns to scale, etc., without worrying about zero values of output(s) and extrapolations to points far from the point of approximation. As an empirical application, we use panel data (1978–1985) on 12 Finnish foundry plants to estimate technical progress, overall returns to scale, product-specific returns to scale and economies of scope.     

External stakeholder engagement: Complementary and substitutive effects on firms' eco-innovation

In this paper, we investigate whether firms' engagements in collaboration agreements with different types of external stakeholders produce complementary effects on the likelihood of eco-innovation. Although collaboration network and open eco-innovation theories affirm that the combination of external partners such as scientific partners, suppliers and customers produces complementary effects on the firm's likelihood of eco-innovation, several empirical studies found the existence of substitutive effects between them. To bridge this gap in the literature, we shape the nature of the interaction between different external partners, analysing an unbalanced panel sample of 10,918 innovative Spanish firms, covering the period 2008–2016. Consequently, we can show how firms benefit the most from collaboration with external partners. Our results show that firms that simultaneously collaborate with scientific partners, suppliers and customers generate partial complementary effects, which increase the firm's likelihood to eco-innovate the most, and that the combination of customer-collaboration with scientific partners, or supplier-collaboration, produces partial substitutive effects. Taking this in account, our results also confirm that engaging with scientific partners, suppliers or customers, independent of one another, increases firms' likelihood of eco-innovation more than noncollaboration. These results have important implications for managers, researchers and policy designers. For managers, this study provides a correct understanding of the benefits that they can expect to obtain from multi-partner external collaboration. For researchers, it introduces the marginal analysis to estimate interaction on nonlinear models. Finally, for policy designers, it shows the need for sponsored R&D collaboration to encourage coordinated ecosystems in which sustainability goals are pursued together.

Early warning systems for currency crises: The Turkish case

Different severe financial crises episodes occurred in the Turkish economy in the last two decades. These crises led to severe economic and social consequences for Turkey in terms of increasing interest rates, large reserves losses, considerable currency depreciations, high output losses and high unemployment rates. This paper aims to illustrate the essential determinants of these crises by developing a multivariate logit model which estimates the predictive ability of sixteen economic and financial indicators in a sample that covers the period from January 1990 to December 2008. The empirical findings show that the Turkish crises are mainly due to excessive fiscal deficits, high money supply growths, sharp rises in short-term external debt, growing riskiness of the banking system (in particular currency and liquidity mismatches), and external adverse shocks.
