我国最低工资政策的就业效应——基于北京市和重庆市建筑业的分析

VAR模型对最低工资就业效应的分析结果显示:北京市的最低工资标准与建筑业就业只是在数理统计上存在关系,并没有实际的经济意义;最低工资对重庆市建筑业的微弱负影响可以忽略不计。最低工资的就业效应并不明显,可以紧密联系行业平均工资来调整最低工资标准,以保障劳动者的基本生活。     

Oil price shocks and volatility spillovers in the Nigerian sovereign bond market

This paper investigates volatility spillover in the Nigerian sovereign bond market arising from oil price shocks, using Vector Autoregressive Moving Average ‐ Asymmetric Generalized Autoregressive Conditional Heteroscedasticity (VARMA‐AGARCH) model. The paper covers the period March 22, 2011 to April 14, 2016 and makes use of the daily data of the Nigerian Sovereign Bond, Brent oil and West Texas Intermediate (WTI), respectively. We endogenously and sequentially detect structural break points using the test of Bai and Perron (2003) framework. In order to accurately estimate the model, we modify it by incorporating the break points into the VARMA‐AGARCH model, a process which if ignored would lead to model misspecification. The results obtained demonstrate a significant cross‐market volatility transmission between oil and sovereign bond market with ample sensitivity to structural breaks. The study also computes optimum weight portfolio and hedge ratio both with and without structural breaks and results equally indicate sensitivity to structural breaks.     

互联网能力与知识能力交互效应对知识创造绩效的传导机制:一个被中介的调节效应模型

整合资源基础观、知识基础观和动态能力理论，探讨互联网背景下互联网能力、知识能力两种企业内部因素交互作用对知识创造绩效的影响过程，尤其关注了具有前瞻性与反应性特征的战略柔性在这一过程中的重要作用，从而构建了一个被中介的调节效应模型。基于我国399家企业调研数据发现，互联网能力、知识能力均对战略柔性有显著正向影响；互联网能力与知识能力的交互作用通过战略柔性的中介机制促进企业知识创造绩效提升，即存在被中介的调节效应。在理论上，丰富了资源基础观和知识基础观在组织竞争优势构建方面的前因研究，在实践上，为处于互联网背景下的企业有效提升知识创造绩效提供了实践参考。     

财政支出差异性对创业活动的激励效应分析

经济新常态下，创业是推动中国经济发展、改善民生的重要途径。创业过程的风险性、不确定性及正外部性需要政府给予积极支持。基于2007-2015年中国内地30个省市（除西藏外）数据，运用动态面板模型，考察地区财政支出和创业活动的关系。研究结果表明：财政支出规模对创业活动数量及创业活动质量具有滞后的积极作用；财政支出规模的滞后效应源于财政支出结构的滞后效应，不同财政支出结构对创业活动质量影响的差异较大；同时，创新是提升创业活动质量的重要手段。因此，政府应积极支持“大众创业、万众创新”，各地区财政创业扶持资金应该从规模和结构上进行调整，重点优化有利于创新的支出结构，为创业提供良好的公共环境。     

The source of global stock market risk: A viewpoint of economic policy uncertainty

This study explores the effect of economic policy uncertainty (EPU) in four countries or regions (China, Japan, Europe, and the United States) on the contagion risk of investments in the global stock market. The stock returns of 22 stock markets worldwide are analyzed to determine which region’s EPU exhibits the greatest effect on regional systematic risk in the global stock market and on volatility risk in individual stock markets. First, all of the samples, the markets of different continents and the spillover indices of the developed and emerging markets, are calculated to observe the dynamic correlation among these markets with the aim of quantifying regional systematic risk and further examining the contagion risk effect of EPU. The results indicate the following: EPU in China is the most influential, and its contagion risk spreads to different regional markets, except for Europe; the effect of EPU in the United States is inferior to that in China; EPU in Japan merely influences contagion risk in emerging markets; contagion risk in European markets is not influenced by the four EPU indices; and EPU in Europe is not influenced by contagion risk in the global stock market. However, according to the volatility risk in each market, the EPU in Europe and China respectively influence Asian countries and European countries the most. These results may be attributable to the extremely high trade dependence among these countries because the performance of international enterprises is mainly determined by the economic policies of their trading partners.     

外资影响我国出口产品质量的差异性研究:从一个地区市场化程度的视角

我国正在经历从出口成本优势向质量优势转型的重要时期。外资对我国出口产品质量的影响及其差异性成为政府和学界关注的问题。本文从市场化水平、政府与市场的关系以及知识产权保护等三个方面检验了制度因素对外资质量溢出的影响。回归结果表明:(1)市场化程度低确实抑制FDI质量溢出;(2)政府干预对外资质量溢出效应产生了负面影响。在低市场化程度或者高政府干预样本组中,FDI质量溢出效应不显著;(3)知识产权保护对FDI质量溢出的影响程度非常有限。本文的结论为政策制定者提供了决策参考依据。简政放权、降低企业面临的行政成本是促进我国本土企业改善其出口产品质量的重要抓手。     

Spillovers between sovereign CDS and exchange rate markets: The role of market fear

As important variables in financial market, sovereign credit default swaps (CDS) and exchange rate have correlations and spillovers. And the volatility spillovers between the two markets become further complicated with the effect of market fear caused by extreme events such as global pandemic. This paper attempts to explore the complex interactions within the “sovereign CDS-exchange rate” system by adopting the forecast error variance decomposition method. The results show that there is a relatively close linkage between the two markets and the total spillover index of the system is dynamic. For most of the past, the exchange rate has a higher spillover effect on the sovereign CDS than vice versa. Moreover, after the market fear variables are introduced, the “sovereign CDS-exchange rate” system and market fear variables present bidirectional spillovers. The results of the study have particular significance for maintaining the financial stability and preventing risk contagion between markets.     

The legitimacy of subsidiary issue selling: Balancing positive & negative attention from corporate headquarters

We consider how in issue selling, subsidiaries draw on different forms of legitimacy to attract corporate headquarters’ (CHQ) positive attention and minimise negative CHQ attention. Through case study evidence, we find that directing CHQ attention to subsidiary issues needs to be executed as a balancing act through forms of subsidiary legitimacy, namely; the personal legitimacy of key individuals at the subsidiary; consequential legitimacy vis-à-vis peer subsidiaries; and linkage legitimacy in the local environment. We develop a typology of subsidiary issue-selling roles and illustrate how negative CHQ attention results from a failure to legitimise issue selling.
