后补贴时代中国新能源汽车产业发展研究

2019年3月,四部委公布新一轮新能源汽车补贴政策,相比2018年标准平均退坡超50%。自政策公布之后,国内新能源汽车市场环境发生巨变,新能源汽车销量增长明显放缓,部分新能源汽车及零部件企业经营困难甚至倒闭,加之以特斯拉为首的外资新能源汽车企业陆续在华设厂投产,使国内新能源汽车市场竞争加剧,下行压力增大,新能源汽车产业正式进入后补贴时代,在此背景下,需要政府部门、相关企业重新评估市场现状,制定新的新能源汽车产业发展战略和路径,推动产业持续健康地发展。     

我国物流业转型升级研究综述

中国经济已经到了只有转型升级才能持续健康发展的关键阶段,产业转型升级在国家政策文件和研究文献中出现的词频较高。文章以我国物流业为研究对象,从现有涉及到物流业转型升级方面的文献挖掘有效信息,梳理我国物流业转型升级研究的历史脉络,从供应链与价值链、产业集群、现代科学技术应用和产业联动四个视角对现有的物流业转型升级文献进行了总结和归纳,并从物流业转型升级的动力研究、阶段性划分研究和演进规律研究三个方面指出了现有文献的研究不足和以后可能的研究方向。其中,供应链与价值链视角侧重于物流企业的纵向角度,产业集群视角侧重于物流企业的横向角度。文章对于物流企业战略设计、政府政策的制定和理论研究具有一定的参考作用。     

知识重叠、知识库特性与创新绩效

以往研究着重探讨重叠/非重叠知识在技术并购中的创新效应，然而在测度知识重叠时仅关注到数量属性而忽略了质量评估。因此，构建一个新的理论框架，利用国家知识产权局2008-2018年专利授权数据，分析217家中国机械制造企业352次国内技术并购案例，探索知识库中重叠、非重叠知识数量和质量属性对并购后创新绩效的影响。结果表明，高质量重叠知识对并购后的企业创新绩效具有正向影响，而高质量非重叠知识则有负向影响。同时，探讨知识数量对并购后创新绩效的影响。研究结果强调了知识重叠对企业获取外部知识的重要性，对企业技术并购实践具有借鉴作用。     

长江经济带生态保护效率与科技服务业发展效率时空关联分析

建立超效率DEA模型并运用视窗分析测算2010-2017年长江经济带11个省市生态保护效率与科技服务业发展效率，通过空间计量模型分析后者对前者的影响。结果表明：科研技术服务业效率对当地及周边地区的生态保护效率具有正向影响；科技资本服务业效率对当地生态保护效率具有正向影响，但对其周边地区有抑制效应；科技宣传服务业未对生态保护效率产生显著影响。据此，提出长江经济带通过提高科技服务业效率改进生态保护效率的对策。     

Enterprise systems’ life cycle in pursuit of resilient smart factory for emerging aircraft industry: a synthesis of Critical Success Factors’(CSFs), theory,knowledge gaps,and implications

The research aims to investigate business value critical success factors (CSFs) of enterprise systems (ES) through their life cycle in pursuit of resilient smart factory for emerging aircraft industry. This article provides an extensive literature analysis of past 22 years based on conscientious criteria of authors: (i) who have published strategic content relevant to CSFs, (ii) received more than 300 citations and (iii) concurrently published two or more papers relevant to ES CSFs. The most cited strategic CSFs were termed as classical CSFs. The 22 CSFs were identified, validated and synthesised for better understanding of success across life cycle by aircraft industry experts. The top 10 empirically verified CSFs have numerous differences with past generic classical CSFs. This article canvases real insights of two distinct views: process and variance approaches of the ES CSFs. The process approach, which is a neglected research area, facilitates the researchers for identification of ES life cycle process coupled with a view of resource deployment when it is needed the most. While the variance approach facilitates practitioners and researchers in finding out which resource (CSF) is relatively more important. The significant findings for ES life cycle can help the practitioners and researchers to make rational decisions throughout the ES life cycle.     

制造企业服务化转型价值效应研究

以2011-2015年制造业上市公司为研究对象，运用实证研究方法，检验了服务化程度对企业价值的影响，以及产业竞争程度对服务化程度与企业价值关系的调节作用。结果表明：服务化程度与企业价值之间呈倒U型关系。当服务化程度较低时，服务化转型会促进企业价值提升；服务化程度达到临界值（37%左右）后，服务化转型会降低企业价值。产业竞争程度对服务化程度与企业价值关系具有调节作用，当前产业竞争程度的提高会降低服务化转型价值效用，而潜在竞争威胁程度的提升会促进服务化转型价值效用。     

Risk-managed industry momentum and momentum crashes

This paper investigates Barroso and Santa-Clara’s [J. Financ. Econ., 2008, 116, 111–120] risk-managed momentum strategy in an industry momentum setting. We investigate several traditional momentum strategies including that recently proposed by Novy-Marx [J. Financ. Econ., 2012, 103, 429–453]. We moreover examine the impact of different variance forecast horizons on average pay-offs and also Daniel and Moskowitz’s [J. Financ. Econ., 2016, 122, 221–247] optionality effects. Our results show in general that neither plain industry momentum strategies nor the risk-managed industry momentum strategies are subject to optionality effects, implying that these strategies have no time-varying beta. Moreover, the benefits of risk management are robust across volatility estimators, momentum strategies and subsamples. Finally, the ‘echo effect’ in industries is not robust in subsamples as the strategy works only during the most recent subsample.     

董事会断裂带与企业薪酬差距

高管与普通员工之间的薪酬差距不仅影响着企业的激励效率与企业价值,还关系到社会的公平与稳定。断裂带是Lau and Murnighan(1998)提出的假想的分割线概念,即可以将团队划分为多个小团体。以2005—2019年中国A股上市公司为样本,本文从董事会断裂带这一视角探索董事会中小团体的差异性对于薪酬差距的影响和后果。本文研究发现:(1)董事会断裂带的存在加剧了企业高管与普通员工之间的薪酬差距;(2)分解董事会断裂带的类型后,由深层特征形成的断裂带对于薪酬差距的影响高于由表层特征形成的断裂带;(3)区分行业竞争的程度后,公司所在行业的激烈竞争有助于缓解董事会断裂带造成的薪酬差距扩大;(4)从经济后果来看,董事会断裂带造成的薪酬差距对企业绩效具有显著的负向影响。本文的研究有助于深入理解企业薪酬差距形成的机制及其后果,同时对于完善我国董事会的监督机制也有一定的现实启发。     

Deal characteristics and M&A performance: How do hospitality firms fare?

The global hospitality industry has experienced significant consolidation in the past several decades. While evidence in the general business literature suggests that the target firm shareholders gain instead of the acquiring firm shareholders, some studies in the hospitality industry have suggested that mergers and acquisitions (M&As) are also beneficial to acquiring firms. Using a comparative study design and a comprehensive sample over 41 years, we empirically examine whether M&As create more value in the hospitality industry than in other industries and whether certain deal characteristics may explain the potential performance differential. Overall, we find that M&As in the hospitality industry outperform M&As in non-hospitality sectors. When examining deal attributes, we find that relative size of target, cash method of payment, and an unlisted target are characteristics positively related to merger performance and help explain some of the performance differential. We contribute theoretically and empirically to the literature by demonstrating that industry and deal effects play an important role in M&A performance.     

制造企业组织柔性、动态服务创新能力与服务创新绩效

随着制造业服务化转型的逐渐深入，服务成为价值交换的核心要素，企业研发工作的重心从产品创新延伸到服务创新。在服务创新背景下，市场需求、关键资源和创新模式的内涵都发生了根本改变，促使企业不断提高自身适应性以应对挑战。然而，目前关于该主题的研究尚不充分。分析并验证了制造企业组织柔性对动态服务创新能力和服务创新绩效的影响。从支撑服务创新的角度出发，将组织柔性划分为组织文化柔性、组织结构柔性和人力资源柔性，分析了组织柔性通过增强企业动态服务创新能力（服务需求感知能力、服务方案开发能力和服务系统重构能力）提升服务创新绩效的作用机制，构建了反映上述概念之间关系的理论模型。以组织市场（B2B）作为研究背景，面向制造企业管理者收集数据，通过实证分析对理论模型进行检验。研究结果表明：组织柔性对服务创新绩效具有积极影响，动态服务创新能力和市场动态性分别在二者间关系中起中介作用和调节作用。最后，就企业如何提高组织柔性，增强动态服务创新能力，进而改善服务创新绩效提出若干建议和对策。
