国外科学工业园管理体制的比较

西方发达国家科学工业园的管理体制更多地借助市场机制的力量,充分调动公司、大学、科研机构和基金会等民间机构管理的积极性。而发展中国家科学工业园的管理体制则更多地借助政府的力量,利用行政手段管理园区。比较国外科学工业园的管理体制,对我国高新区管理体制的创新具有重要借鉴意义。     

利用大数据分析技术的智能化网络故障诊断系统

随着网络技术的快速发展以及各种新网络业务的出现,网络的规模日益扩大和复杂。同时,各种网络服务对于网络可靠性的要求也逐渐提高,这就对网络的维护提出了更高的要求。在这种情况下,传统的网络维护模式逐渐不能适应现代网络发展的需求。针对现代大型网络的故障诊断问题,利用大数据分析技术,设计并完成了一套整体的智能化故障诊断系统。在此系统中,针对不同的故障类型,利用能够获取到的数据类型,针对性地设计了相关的故障诊断模块和算法。系统整体基于开源的数据处理平台构建,具备良好的可扩展性。通过实际案例数据的验证,结果表明此系统具备良好的处理实际网络故障的能力,将大数据分析技术应用于网络故障诊断领域也具备较强的可行性。     

IT与业务匹配中的信息化冲突探索

信息化冲突是企业信息技术(IT)与业务匹配中普遍存在的重要障碍之一。本文在对现有文献整理基础上,对IT与业务匹配中信息化冲突产生的原因进行了系统的分析,将信息化冲突划分为任务冲突和关系冲突两种类型,并对二者之间的关系进行了分析。从行为整合角度给出了解决信息化冲突的途径。     

Employee stock ownership and financial performance in European countries: The moderating effects of uncertainty avoidance and social trust

This study investigates how the effect of employee stock ownership on financial performance may hinge on the diverse cultural and societal contexts of European countries. Based on agency and national culture theories, we hypothesize that the positive relationship between employee stock ownership and return on assets (ROA) is stronger in those nations with lower uncertainty avoidance and higher social trust. Using a multisource, time‐lagged, large‐scale dataset of 1,741 firms from 21 countries in Europe, our multilevel, random coefficient modeling analysis found evidence for these hypotheses, suggesting that uncertainty avoidance and social trust serve as important contextual cues in predicting the linkage between employee stock ownership and financial performance. Our supplemental analysis with distinction between the managerial and nonmanagerial employee stock ownership further indicates managerial employee stock ownership has a direct positive effect on ROA. Although nonmanagerial employee stock ownership had a nonsignificant association with ROA, the relationship was positive and significant when uncertainty avoidance was low and social trust was high. This research contributes to the existing literature by illuminating some of the contextual influences altering the effectiveness of employee stock ownership. Our findings also offer practical suggestions for effectively using employee stock ownership.

行政垄断加剧了企业生存风险吗?

在转型升级的关键阶段,定量地评价行政垄断与企业战略选择之间的关系,对推动《公平竞争审查制度》的理论与实践探索以及改善企业生存的制度环境都具有重要意义.但既有研究中,行政垄断的政策效应分析较少深入到微观企业层面,特别是从企业生存的视角来进行的评估.文章采用PSM-Cox比例风险模型,以企业微观数据首次检验了行政垄断对企业生存风险的影响效应及其机制.研究表明,行政垄断对制造业企业的生存风险产生了显著效应,即以行政垄断为代表的政府干预会加剧企业生存风险.同时,行政垄断对不同所有制、地区及行业的企业的影响存在异质性,会显著加剧非国有企业、中西部地区企业及劳动密集型行业企业的生存风险.而行政垄断对企业生产率、企业创新与寻租行为所产生的效应或许是本文总体结论的重要解释.     

扁平证券市场线和融资限制——中国股票市场的实证检验

资本资产定价模型（CAPM)在国际金融市场的实证检验结果往往呈现扁平证券市场线现象。一些学者认为融资限制是该现象的产生原因。本文旨在研究扁平证券市场线现象是否存在于中国股市,同时分析融资限制对中国股市证券市场线的影响。本文采用投资组合分析法对A股主板市场进行实证检验。本文研究发现：（1)扁平的证券市场线现象同样存在于中国股票市场中;（2)在中国股票市场中,融资限制与证券市场线的斜率呈负相关,与截距呈正相关,这符合融资限制理论;（3)以上两点发现同样存在于多因子定价模型中,这表明本文研究结果具有稳健性。

The effect of travel purpose and self-image congruency on preference toward airline livery design and perceived service quality

This paper examines travelers’ preference for airline livery design, which is an important component of sensory experience for tourists. Based on surveys of both U.S. and South Korean respondents, this study finds that airline livery preference depends on travel purpose (i.e. business vs. vacation). Designs preferred by the two travel segments differ in terms of color tone, hue, line, and shape. Business traveler-preferred designs signal punctual, efficient, classy, and safe service; while vacation traveler-preferred designs elicit feelings of fun, friendly, and exotic service. It is also shown that travelers prefer airline livery that is congruent with their situational self-image, depending on the travel occasion at hand. In fact, self-image congruency of design is approximately half of the variance in airline livery preference. Finally, results show that self-image congruency also increases perceived service quality.
