数字技术应用情境下如何提升企业创新效应? 协同自发抑或协同响应

数字技术能够对组织协同创新活动以及数字经营环境产生差异化影响,重塑企业创新效应形成机制与实践路径。因此,深入探究数字技术与组织、环境间的联动交互及组态匹配关系对特质各异的企业协同创新路径研究具有重要意义。基于协同视角构建数字技术应用情境下的TOE分析框架,通过对64家数字密集型企业进行模糊集定性比较分析,结果表明：组织与数字技术在多主体协同过程中的交互方式主要分为协同自发与协同响应,具体包含4种组态类型。协同自发方式主要包括以高层次人才为主导的人才驱动型与以组织开放度为主导的文化引领型;协同响应方式主要包括以地区经济发展水平为主导的需求推动型与以政府注意力分配为主导的政策拉动型。结论能够为解释企业创新应用数字技术提供新的理论视角,为不同技术条件与资源禀赋的企业提供针对性协同策略,为我国协同创新实践提供新的优化路径,为推动数字经济高质量发展提供新的指导方向。     

The effect of banking crisis on bank-dependent borrowers

We provide causal evidence that adverse capital shocks to banks affect their borrowers’ performance negatively. We use an exogenous shock to the U.S. banking system during the Russian crisis of Fall 1998 to separate the effect of borrowers’ demand of credit from the supply of credit by the banks. Firms that primarily relied on banks for capital suffered larger valuation losses during this period and subsequently experienced a higher decline in their capital expenditure and profitability as compared to firms that had access to the public-debt market. Consistent with an adverse shock to the supply of credit, crisis-affected banks decreased the quantity of their lending and increased loan interest rates in the post-crisis period significantly more than the unaffected banks. Our results suggest that the global integration of the financial sector can contribute to the propagation of financial shocks from one economy to another through the banking channel.     

Which firms engage small, foreign, or state banks? And who goes Islamic? Evidence from Turkey

We study a representative dataset from Turkey that identifies firm–bank connections. Banks in Turkey differ not only in size and nationality, but also in ownership and orientation (non-Islamic versus Islamic)—resulting in at least six distinct bank types. We estimate a multinomial logit of the choice by the firm of bank type. We document a strong correspondence between bank type and firm characteristics that is not always the same as has been documented so far for US datasets. For example, small firms engage large rather than small banks. Young, large, multiple-bank, and industry-diversified firms, that are located in or close to Istanbul, team up with foreign banks. Islamic banks mainly deal with young, multiple-bank, industry-focused and transparent firms.

Assessing the regional digital divide across the European Union-27

Despite the efforts devoted to the analysis of the digital divide over the last years, the regional evidence on this issue is still scarce. Within this context, the goals of this paper are twofold: (1) measuring the digital divide across the regions of the 27 Member States and within each country and (2) explaining the observed regional disparities. The analysis leads to identify Dutch regions as the Top-10 in ICT, while Greece and Bulgaria occupy the Bottom-10. Therefore, results show that the regional digital divide reflects to some extent the income gap. However, regional policy seems to be having some positive implications for technology adoption. In particular, the rural-versus-urban dimension of the digital gap appears to be less important than it is usually claimed to. Likewise, some evidence is found of the role of cultural and institutional factors in ICT adoption, an issue that has not been previously analyzed at the regional level.     

菲涅耳非相干全息术3D全息成像探讨

全息成像提供了一种从单一观察点捕捉具有完整三维信息画面的可靠、快捷的方法。本文回顾了近期提出的单通道菲涅耳数字全息光学系统,该系统能获得由非相干光照射的三维实物体的全息图。在这一静态全息技术中,由三维物体反射或发射光,在通过空间光调制器（SLM）后,用数码相机记录。SLM被用作单通道非相干干涉仪的分束器,使来自物体上各点的球面波被分成两束具有不同曲率半径的球面波。所有球面波干涉结果的非相干总和,即可生成被观测物体的三维菲涅耳全息图。在计算机中可再现该全息图,使其三维特征得以呈现。     

一种面向智能变电站和生产管理系统设备在线监测的数据转换模型

在线监测是实现电网设备状态检修和生命周期管理的前提,而有效的设备数据转换模型是在线监测的基础。通过对智能变电站及生产管理系统的标准、规范进行分析,提出一种用于智能变电站和生产管理系统设备在线监测的数据转换模型。对生产管理系统的设备信息数据模型进行分类总结,基于交换用XML数据对生产管理系统和IEC 61850标准数据模型进行对比,对变电站设备的铭牌信息、运行信息以及监测信息采用标签映射与ID索引相结合的方法,实现智能变电站到生产管理系统的数据转换。     

金融科技与银行价值链的重塑

金融科技在显著提升银行服务水平和经营效率的同时,也对银行业的竞争环境产生了深刻影响,商业银行在服务场景和渠道、客户信息以及资金等方面的传统竞争优势受到挑战.为快速获取必要的金融科技能力,银行加速推进数字化转型,并在其价值链的多个环节与科技企业开展合作.银行价值链由封闭的自我循环模式转向开放的合作模式,且价值链中的高附加值活动存在向少数企业集中的趋势.银行业的风险特征也由此发生重要变化:传统的战略风险、信用风险、流动性风险、操作风险、法律风险与系统性风险依然存在且变得更加复杂;科技风险、网络风险与数据安全等问题日渐凸显.作为应对,我国应结合银行业的实际情况,对现有银行监管框架和模式进行再评估,督促指导银行在推进数字化转型的过程中密切关注相关风险,进一步加强监管能力建设,以更好地守住不发生系统性金融风险的底线.     

银行价格竞争、融资约束与企业研发投资——基于“中介效应”模型的实证研究

近年来我国利率市场化改革积极推进,实体经济发展积极向创新驱动转型,一个亟须研究厘清的关键问题是,银行业竞争如何驱动企业创新活动?本文关注银行价格竞争对企业创新的影响,以2013—2018年沪深两市的上市企业为样本,采用"中介效应"因果分析模型,实证检验了银行价格竞争对企业研发投资的影响,并识别出以融资约束为中介渠道的作用机制。研究发现,银行价格竞争不仅会提高银行的风险容忍度,直接增加R&D投资的信贷供给意愿,而且还会通过降低贷款价格和增加贷款可得性来缓解企业整体的融资约束,间接促进企业创新活动。这一机制在解除贷款利率管制之后以及在民营企业层面体现得更加明显。本文的研究结果对于深化金融市场化改革、改善金融服务实体经济效果以及实施经济创新驱动发展战略,具有明确的政策启示。
