创新生态系统视角下价值共创如何影响企业创新绩效——一个有调节的中介模型

以创新生态系统为视角，引入创新资源互动与生态系统规范机制为中介变量和调节变量，探究价值共创如何影响企业创新绩效。基于307家企业样本数据，运用结构方程模型、Bootstrap和层级回归方法对数据进行分析。研究发现：创新生态系统中，价值共创不完全直接影响企业创新绩效；创新资源互动部分中介价值共创对企业创新绩效的影响；生态系统规范机制部分正向调节价值共创对创新资源互动的影响。最后提出，创新生态系统调控方与企业要差异化地制定提升创新绩效的实施方案，营造活跃的创新资源互动氛围，形成并完善系统内生态规范机制。     

Consumers’ valuation for food traceability in China: Does trust matter?

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.     

高校跨学科创新团队知识互动程度评价研究

知识互动程度评价对改善高校跨学科创新团队知识互动具有重要意义。在界定高校跨学科创新团队知识互动及知识互动程度内涵的基础上，创新性地从知识互动深度、互动广度、互动时间3个维度建立知识互动程度评价指标体系。进一步地，采用三角模糊权重、熵权和模糊积分相结合的方法，构建知识互动程度评价模型。最后，选取一所高校跨学科创新团队进行实例分析，验证评价模型的可操作性，可为高校跨学科创新团队知识互动程度评价提供一个新视角。     

Enhancing relationships in e-tail: Role of relationship quality and duration

This research deals with antecedents and outcomes of relationship quality in e-tail. SMART-PLS analysis of survey data from India (n = 644) showed that perceived value, e-service quality, interaction, discounts and transaction related factors were found to have a positive effect on relationship quality (RQ). RQ mediates the relationship between these antecedents and self-brand connect and loyalty. Support for serial mediation was found with RQ and self-brand connect preceding loyalty formation. Relationship duration positively moderated the effect of RQ on self-brand connect. RQ was conceptualized as a formative second order factor. E-tailers may invest in antecedents of RQ and they may devise strategies to increase the duration of relationships.     

Multi-scale interactions between economic policy uncertainty and oil prices in time-frequency domains

Dynamic interactions between policy uncertainty and economic activity, including oil prices, have attracted increasing amounts of scholarly interest, but few studies have considered the inherent feature that the entire market is composed of different stakeholders operating in different time horizons. To fill this gap and address this issue, this paper proposes a multi-scale correlation framework. Specifically, we use the wavelet coherence method and scale-by-scale linear Granger causality tests to explore the co-movement and causality of pairs of economic policy uncertainty indices of G7 countries, China, Brazil, and Russia and West Texas Intermediate (WTI) oil prices. Our results show that the interaction between economic policy uncertainty and oil prices in the short-term is weak but gradually strengthens towards the long-term, especially when significant historical political or financial events occurred. Moreover, a consistent conclusion is that the interaction is negative in the medium-term, while it is positive in the long-term. Further, Granger causality tests at different time-scales show that no Granger causality from economic policy uncertainty to oil prices exists in the short-term for all sample countries, except the US, while there is a strong unidirectional or bidirectional Granger causality for all researched countries in the medium- and the long-term.     

创新要素流动与产业结构变迁关系及其空间溢出效应研究

创新要素流动既是优化资源配置的关键，又是产业结构调整的内在动力，反之，产业结构变迁又会通过微观效应推动创新主体创新。基于1998-2018年内地30个省市面板数据，研究了创新要素流动与产业结构变迁的互动关系及空间溢出效应。回归结果表明：R&D人员流动对本地区产业结构高级化以及其它地区产业结构合理化具有促进作用，同时，抑制了本地区产业结构合理化与溢出地区产业结构高级化；R&D资本流动对本地区产业结构高级化以及其它地区产业结构合理化具有抑制作用，但是对本地区产业结构合理化以及其它地区产业结构高级化具有促进作用；产业结构合理化对R&D人员及R&D资本流动具有促进作用，但是抑制了其它地区的R&D资本流动。     

Designing futures: Inquiry in climate change communication

There are many barriers and challenges associated with climate change communication focused on promoting community-based action for sustainable futures. Of particular interest is the challenge to embed community perspectives in a communication process of climate change solutions. In this paper we argue that 3D interactive simulations using design inquiry as a development process, can be an effective way of communicating climate change solutions and multiple community responses. People are more likely to engage with the challenges associated with complexity of climate change at the local level when their perspectives are integrated into viable and multiple pathways for action. Future scenarios of change processes situated in local experiences in compelling and interactive ways can be disseminated holistically by making links between scientific, social, political, economic and cultural elements. Design inquiry, as a research approach, integrates contextual knowledge into communication processes to aid imagining, re-thinking and reembodying viable pathways that explore the kinds of futures we collectively envision. This paper examines the contributions that design inquiry makes to climate change communication using an interactive simulation environment for designing futures. We discuss these ideas using the example of the Future Delta project, a virtual 3D environment that enables the exploration and simulation of multiple community-based climate change solutions in the Corporation of Delta, British Columbia.     

互联网能力与知识能力交互效应对知识创造绩效的传导机制:一个被中介的调节效应模型

整合资源基础观、知识基础观和动态能力理论，探讨互联网背景下互联网能力、知识能力两种企业内部因素交互作用对知识创造绩效的影响过程，尤其关注了具有前瞻性与反应性特征的战略柔性在这一过程中的重要作用，从而构建了一个被中介的调节效应模型。基于我国399家企业调研数据发现，互联网能力、知识能力均对战略柔性有显著正向影响；互联网能力与知识能力的交互作用通过战略柔性的中介机制促进企业知识创造绩效提升，即存在被中介的调节效应。在理论上，丰富了资源基础观和知识基础观在组织竞争优势构建方面的前因研究，在实践上，为处于互联网背景下的企业有效提升知识创造绩效提供了实践参考。

社会保障与区域经济互动机理及协调度研究

本文立足于社会保障与区域经济协调发展的作用机理,构建了反映社会保障与经济发展两大系统的指标体系及耦合协调模型,然后采用2008年的指标数据,计算并评价了各省市社会保障与经济发展两大系统的协调性。研究表明：社会保障与经济发展水平呈现显著的正相关关系,经济发展水平高的省份,其社会保障水平也相对较高,表现出明显的从东部到中西部的梯度递减趋势;东部地区省份和大部分中部地区省份,社会保障水平滞后于经济发展水平,而西部地区则与之相反,社会保障水平高于其经济发展水平;从协调度所属等级来看,类似于＂橄榄球＂状,优质协调和严重失调的省份较少,基本协调和轻度失调的较多,且东部地区协调度明显优于中、西部地区。
