How do relational bonds affect user engagement in e-commerce livestreaming? The mediating role of trust

E-commerce livestreaming depends heavily on user engagement. However, the effect of relational bonds (i.e., financial bonds, social bonds, and structural bonds) on user engagement in e-commerce livestreaming has not been well understood. Our study develops a conceptual model to investigate the impacts of relational bonds on user engagement and addresses the mediating role of trust. We collected data from users of the DianTao App. The results show that social bonds and structural bonds positively affect user engagement, while financial bonds have no direct impact on user engagement. Financial bonds, social bonds, and structural bonds are positively related to trust in the broadcaster. Similarly, financial bonds, social bonds, and structural bonds are also positively associated with trust in the platform. Furthermore, trust in the broadcaster and trust in the platform directly affects user engagement, fully mediating the impact of financial bonds on user engagement, while partially mediating the impacts of social bonds and structural bonds on user engagement. In addition, we find that experience moderates the mediating effects of trust between relational bonds and user engagement. The findings of this study provide useful insights for operators who should invest in building relational bonds and user trust to improve user engagement in e-commerce livestreaming.

关系嵌入、知识获取与BOP市场导向的产品创新：内外部不确定性的调节作用

在主流市场日趋饱和的背景下,更多企业将目光聚焦于金字塔底层市场。基于权变视角,探索企业在BOP跨部门合作网络中,双边关系耦合与网络嵌入交互构建的双环协同机制如何影响企业外部知识攫取,进而作用于BOP市场导向的产品创新。采用大样本问卷调查,收集396家电动自行车企业数据,利用多元回归分析对研究假设进行实证检验。研究表明,跨层级嵌入双环协同机制与知识获取呈倒U型关系,高外部不确定性会增强该倒U型关系,但高内部不确定性对该倒U型关系无显著影响;通过知识获取的部分中介传导效应,最终跨层级嵌入双环协同与BOP产品创新呈倒U型关系。结论对企业把控BOP网络嵌入程度、优化网络配置及网络治理具有一定指导意义。     

基于灰色关联分析的企业IT应用水平提升路径研究

在实证调研的基础上,应用灰色关联理论,对企业的管理制度能力和流程管理能力与IT应用水平进行灰色关联分析,发现企业IT应用水平不同阶段,这两种能力与IT应用水平的关联度存在差异,表明企业IT应用发展规律在不同IT应用阶段相对应的制度能力和流程管理能力不同。由此,提出企业在选择提升IT应用水平路径上应当关注在不同时期与IT应用水平相对应的制度能力和流程管理能力的培育和强化。     

领导企业治理下创新生态系统演进路径研究

关于创新生态系统参与主体风险冲突及治理的研究,目前只停留在风险产生原因及应对策略方面,主要侧重于静态视角,鲜有文献从创新生态系统演进过程动态视角,并结合创新生态系统驱动主体领导企业考察风险防范和治理问题,而后者对于创新生态系统可持续发展更为重要。构建了领导企业治理的创新生态系统由契约规则到关系规则演化路径分析框架,并以比亚迪新能源汽车创新生态系统为案例进行实证研究。从创新生态系统形成初期领导企业主导的契约治理到成熟阶段关系治理是一个连续不间断的演化过程,基于领导企业治理的创新生态系统演化路径,包含契约规则主导的协同创新到契约规则向关系规则转换的创新网络形成再到由关系规则主导的开放式创新3个阶段,该过程以领导企业借助创新生态系统规范化设计完成整个创新生态系统互动、协同为主要形式。治理重点从企业间契约治理向领导企业主导的对整个创新生态系统关系治理转移,契约治理则转化为由领导企业主导以网络化设计为基础的关系互动和协同治理。

并行工程视角下产品绿色设计评估模式构建

环保性的相关决策及绿色产业是未来企业实现可持续发展所必须重视的议题。因此,运用并行工程的概念构建了一套新产品进行绿色设计时评选开发方案的评估模式,并结合模糊理论及灰色系统的理念与方法以处理决策过程中可能存在的不确定性、模糊性及评估过程中信息不完整性的情况,最后以模拟的方式完成此评估模式。     

A grey decision and prediction model for investment in the core competitiveness of product development

Because enterprises do not disclose their internal specific cost information to the public and, moreover, every firm has its own product character and financial constitutions, it is difficult to offer fixed guidelines for investment decisions. Thus, an enterprise may be uncertain when required to choose the most promising set of possible investments.The goal of this research is to use a grey relation analysis and analytic hierarchy process (AHP) to probe the core product development and competitiveness of an enterprise from limited data and, furthermore, by constructing the grey model, GM(1,1), to validate the feasibility of this assessment of the core competitiveness and investment strategy. In this study, a precision mechanical manufacturer is taken as an example, and the forecast estimate from this method is compared to those of a linear regression and the actual values to demonstrate the feasibility of applying this methodology to investment decision making, hence, demonstrating the value of this research.
