基于云模型的装备制造业产业链风险评价

将云模型引入风险评价,对装备制造业风险等级进行量化。从产业链的视角,将专家调查法与熵权法相结合识别风险因素,将筛选出的具有显著影响的因素作为评价因子引入云模型,从而降低了风险评估结果的主观性。构建了产业链风险评价指标体系,提出了基于熵权-云模型法的风险评估方法,对装备制造业产业链风险进行了总体评估。通过分析评估结果,提出防范装备制造业产业链风险的对策建议。     

The World Is Not Enough! Small Open Economies and Regional Dependence

In this paper, we explicitly introduce regional factors into a global dynamic factor model. We combine new open economy factor models (emphasizing global shocks) with the recent findings of regional importance in the business cycle synchronization literature. The analysis is applied to a large panel of domestic data for four small open economies. We find that global and regional shocks explain roughly 30 and 20 percent, respectively, of the business cycle variation in all countries. While global shocks have most impact on trade variables, regional shocks explain a relatively large share of the variation in cost variables.     

Trade credit in SMEs: a quantile regression approach

This article analyses the determinants of the trade credit in Spanish manufacturing small and medium-sized enterprises (SMEs) from a new perspective. Specifically, we focus on the relationship between trade credit and other relevance financial resources: bank credit and self-financing. For the first time in the literature, a quantile regression approach is used, which takes into account the heterogeneity of firms in different quantiles of trade credit distribution. Our results show that the relationship between trade credit and other financial sources presents dissimilarities, including differences in sign, on SMEs with different degrees of trade credit. Our findings help to clarify the confusing results achieved in previous research on this topic.     

中国资本账户开放进程中跨境证券投资对国内金融市场的影响*

随着中国资本项目开放进程的推进,跨境证券投资对国内金融市场的冲击日益增强。在此背景下,本文首先通过构建考虑了资本市场收益率以及有管理浮动汇率制度的IS LM BP模型对跨境证券投资与中国国内金融市场的相互影响机理进行了理论探究,并基于中国2005年7月—2016年8月的月度数据,运用马尔科夫区制转移向量自回归模型对中国资本账户开放进程中跨境证券投资与人民币汇率、股票市场收益率、短期利率的联动关系进行了实证分析。研究结果表明：第一,四者的关联性存在明显的区制特征,区制1主要包括次贷危机时期（2007—2008年）、欧债危机时期（2010—2012年）以及后金融危机时期（2015—2016年）,经济呈现“股票市场收益率较低、跨境证券投资较少、短期利率较高、金融市场波动性大”的状态;区制2主要包括次贷危机前夕（2005—2006年）、次贷危机后的量化宽松时期（2009—2010年）以及欧债危机后的调整期（2013—2014年）,经济呈现“股票市场收益率较高、跨境证券投资较多、短期利率较低、金融市场波动性小”的状态。第二,当处于资本市场化进程较快、金融市场波动性较大的区制阶段（区制1）时,跨境证券投资与国内金融市场的联动关系更加明显。本文研究结论对于我国进一步开放资本市场具有借鉴价值和政策启示。     

Modelling price transmission and volatility spillover in the Slovenian wheat market

Interdependence between first and second moments of producer and consumer wheat prices in Slovenia is assessed, in light of the recent major historical events that the country has undergone, as well as the recent rumours of cartel agreements between millers causing a decline in farm-gate prices, while leaving consumer prices untouched. A threshold vector error correction and multivariate generalized autoregressive conditional heteroscedasticity model with exogenous variables is applied. Results indicate that price-level adjustments mainly favour retailers by increasing their marketing margins. Important second-moment interactions are also identified. Increases in international wheat stocks reduce producer prices, while higher interest rates increase their instability.     

How pervasive is the effect of culture on stock market linkages? Evidence across regions and economic cycles

We conduct a comprehensive study on the effect of culture on stock market linkages. With data on 25 national stock markets, a quantile regression model is used to estimate the determinants of market linkages using culture variable/s such as language, religion and Hofstede’s cultural dimensions while controlling for distance, economic and legal variables. Further, we test whether these effects hold across regions and if changes are detected during periods of market crisis. We also test if market liquidity, an indicator of market efficiency, diminishes the impact of culture on market linkages. The main conclusion is that culture preferences shape investor choices, which affects integration between stock markets. The equity markets with similar cultural traits tend to increase market linkages; however, we observe differences across regions. Furthermore, liquidity and economic uncertainty fail to have an impact on the significance of culture variable/s as determinants of market linkages.     

Inter-Industry Wage Differentials in Greece: Evidence from Quantile Regression Analysis

Using a consistent estimator of the covariance matrix of the asymptotic distribution of the quantile regression estimator with intra-cluster correlation of the error terms, the paper investigates whether and to what extent inter-industry wage differentials derive from worker heterogeneity in the form of unobserved quality. To conduct this study, we pioneer in utilizing a unique data set, the European Union Structure of Earnings Survey for Greece, which follows a two-stage random sampling approach of employees clustered within firms. Data refer to 2010 when the first elements of the economic adjustment programme to deal with the chronic deficiencies of the Greek economy and restore sustainable public finances, competitiveness and set the foundation for long-term growth, gained visibility. Results point to high wage dispersion across industries at the mean of the conditional wage distribution, even after controlling for personal and workplace characteristics. However, evidence for the unobserved heterogeneity hypothesis is rather scant. Therefore, there is room for efficiency wage or rent-sharing theories in accounting for a large part of inter-industry wage differentials tentatively implying that firm heterogeneity in the ability to pay matters more than employee unobservable attributes in the wage determination process.     

风险因子调整的三阶段剩余收益模型的应用研究——基于中国资本市场1999～2010年截面数据分析

在总结梳理奥尔森模型及后来学者所提出的系列三阶段剩余收益模型基础上,选择有代表性的三阶段剩余收益模型（TSSV-θ）,结合作者提出的新的三阶段剩余收益模型,即风险因子调整的三阶段剩余收益模型（RIM-σ^2）,利用中国市场的数据进行实用性比较研究,同时选择单一上市公司数据就RIM-σ^2模型进行实际的运用分析。结果表明,RIM-σ^2模型在理论和实证上均具有较好的优越性和实用性,可以作为一种有效的企业价值评估方法。     

基于AHP-NRCA模型的环渤海地区海洋功能评价

根据系统结构决定系统功能的原理,从结构视角出发,利用环渤海地区17个沿海城市2007—2009年相关数据,对环渤海地区沿海城市海洋功能进行测度与评价,采用NRCA模型计算各城市海洋功能的比较优势指数。结果表明,评价结果同现有海洋功能区划结果基本吻合,但海洋生态环境功能更加突出,体现了可持续发展原则。为了获得海洋开发的最大收益,在环渤海区域海洋经济一体化进程中,各沿海城市要有计划地根据海洋功能的比较优势来进行优化资源配置与产业布局调整。
