跨界搜寻的创新驱动力：一个有调节的中介模型

以来自4个省份的357家企业为研究对象,以动态能力理论为基础,探讨跨界搜寻对技术创新的影响,以及动态能力和技术动荡在其中的中介与调节作用。结果发现：跨界搜寻的两种类型搜寻（技术知识和市场知识）对组织技术创新具有显著正向影响。同时,动态能力中介两类跨界搜寻和技术创新之间的正向关系,在技术知识跨界搜寻与技术创新之间发挥完全中介作用,在市场知识跨界搜寻与技术创新之间发挥部分中介作用。此外,组织外部较高的技术动荡水平不仅会加强动态能力对技术创新的正向影响,还会强化动态能力在两种类型搜寻与技术创新之间的中介效应。     

The effect of foreign currency hedging on the probability of financial distress

This paper investigates the effect of foreign currency hedging with derivatives on the probability of financial distress. I use Merton’s (1974) structural default model to compute firms’ distance to default as a proxy for their probability of financial distress. Using an instrumental variables approach to control for endogenous hedging and leverage, I find that the extent of foreign currency hedging is associated with a lower probability of financial distress. Whereas previous research finds that the probability of financial distress is a determinant of a firm’s hedging policy, this paper provides direct evidence supporting the hypothesis that the extent of hedging reduces a firm’s probability of financial distress.     

地方产业集群升级的两维性分析

发展中国家大多数地方产业集群处于低端市场竞争的低端路线,迫切需要产业升级。通过论述全球价值链背景下的集群创新与升级的互动关系,提出了产业集群升级的两维性机理及其实现要素：既要提升集群区位的“内生性要素”对创新活动的影响,包括生产要素升级、区域品牌升级、社会资本升级、区域创新系统升级;也需要借助全球网络联系对获取知识等资源的杠杆利用,提升市场、技术能力。这样,建立在持续性创新的基础上,才能保证嵌入全球价值链的地方产业集群创造、保持和捕捉更多的价值。     

Endogenous innovation and imitation in a model of equilibrium growth

This paper provides a growth model in which innovation as well as imitation occurs. Economic growth is due to product innovations. Innovators driven by the possibility to appropriate monopoly profits do not remain in their monopolistic position forever. Latecoming imitators get into possession of the private knowledge of production through investments in R & D. Imitated products are marketed in oligopolistic markets. Imitation proves to be profitable despite a single factor market and positive imitation costs. A steady-state equilibrium with positive imitation and innovation rates as well as different market structures can be derived. Finally, the effects of industrial policy measures are discussed.     

创新型城市创新效率评价与投入冗余分析

推动创新型城市建设,是我国实施创新驱动发展战略的重要抓手。运用数据包络分析方法（DEA）,综合考虑创新的经济产出、科技产出和社会环境效益,构建CCR和BCC模型,测算了2013- 2014年53个国家创新型试点城市的综合效率及其分解的纯技术效率和规模效益,对非DEA有效城市的投入冗余进行了对比和原因分析,并根据创新型试点城市创新效率测算结果,提出了推进创新型城市建设的政策建议。     

Innovation and efficiency: It is possible to have it all

A firm that simultaneously engages in a high degree of both innovation and efficiency follows an approach that is often referred to as an ambidextrous strategy. Surprisingly, relatively few firms are able to balance these two emphases. Internal battles for resources often tip the scales in favor of efficiency over innovation, or vice versa. Management gurus frequently warn that simultaneously pursuing both can set the firm up for mediocre performance, yet the turbulent nature of today’s markets and cut-throat competition create a renewed need for firms to reconsider this dual approach for longer-term success. Unfortunately, practical insights from empirical studies regarding performance benefits and implementation issues are still scant. Perhaps this is one reason why few firms are successful in both efficiency and innovation. In this article, we provide evidence—using a cross-industry survey of senior marketing managers in publicly-traded U.S. firms—that firms which successfully employ an ambidextrous strategy outperform those which overemphasize either efficiency or innovation. Furthermore, we highlight marketing’s role as an example of the often overlooked need for successful functional implementation. Finally, we provide useful methods for managers to answer three key questions: (1) Is my firm ambidextrous?; (2) Should my firm be ambidextrous?; and, if so (3) How can my firm become ambidextrous?     

基于软系统方法的整合创新模型研究

创新过程从本质上讲是一个无结构系统创立或变革的过程,而处理无结构、多目标复杂问题正是软系统方法的优势。在借鉴国外相关创新模型的基础上,提出了一个基于软系统方法的整合创新模型。     

低碳背景下我国制造业绿色创新系统演化过程:创新系统功能视角

在低碳发展要求下,我国制造业绿色创新系统快速发展,呈现出不同演化特征。应用动态创新系统功能分析框架,对低碳背景下我国制造业绿色创新系统的演化过程进行分析。研究发现,在低碳背景下,我国制造业绿色创新系统的演化包含3个阶段:初创阶段、形成与成长阶段、成熟与转移阶段。一般来说,在创新系统演化的不同阶段存在若干不同的系统功能作用模式,其中,只有一种模式发挥主导作用。最后,基于以上分析,针对我国制造业绿色创新系统的不同演化阶段提出政策建议。     

创新要素流动对城市群协同创新的影响——基于长三角城市群与长江中游城市群的实证

利用2006-2017年长三角城市群和长江中游城市群共41个地级市面板数据,首先,运用拓展DEA法对两大城市群协同创新水平进行测度,然后,采用空间计量模型实证考察创新要素流动对城市群协同创新的影响,进一步以互联网发展水平为门限变量,构建门限模型,探析互联网发展对创新要素在城市群流动的协同创新效应是否存在门限效应。研究发现：创新要素流动对城市群协同创新影响的总效应显著为正,空间正向溢出效应显著,且存在群际差异;在两大城市群内,创新要素流动对城市群协同创新影响呈现非线性,创新人员流动对城市群协同创新影响呈“倒U型”特征,创新资本流动对城市群协同创新影响呈“U型”关系,相应拐点在不同城市群呈现异质性。     

债转股：功能缺陷与制度依赖

债转股是银行保全资产的一种重要方式, 但其在政策设计和化解宏观金融风险及银企债务等方面存在功能缺陷。债转股对国有企业的制度变迁形成很强的依赖, 而债转股改革能否取得成功, 则取决于国有银行制度的变迁
