关系质量对企业知识创造绩效的作用机理：一个被调节的中介模型

基于嵌入性视角，分别引入知识转移、合作模式作为中介变量和调节变量，深入探究关系质量影响企业知识创造绩效的内在机理。利用277份来自全国多地的制造业及高新技术企业调查问卷，采用多元回归方法进行实证研究。结果表明：经济型和社会型关系质量均正向影响企业知识创造绩效；社会型关系质量通过元素知识和架构知识转移正向影响企业知识创造绩效。在契约治理模式下，经济型关系质量更倾向于通过元素知识转移正向影响企业知识创造绩效；在股权治理模式下，社会型关系质量更倾向于通过架构知识转移正向影响企业知识创造绩效。     

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。     

Performance effects of innovation in two-sided markets: The paradigmatic case of OTAs

Online Travel Agents (OTAs) play an important intermediary role in the two-sided travel distribution market. A critical factor that enhances a firm's competitive advantage is innovation. Yet, the analysis of innovation in the OTA context is scarce. The main objective of this article is to fill this gap and examine the effect of OTA innovations on firm performance. We analyze the effect of two-sided market specific innovations (same-side and cross-side) on performance and contribute to the literature by expanding the theoretical understanding of innovations. We find that producer-to-consumer innovations have a greater effect on OTA performance than producer-to-producer and consumer-to-consumer innovations. A fundamental managerial implication is that exchange management is an area to be enhanced when innovating in travel market distribution.     

Because you're worth it? Determinants of Vice Chancellor pay in the UK

Wage inequality has increased across most developed nations; this has been manifested in a wide range of organisations and sectors, with implications for well‐being and sustainability; within UK universities, this has become increasingly visible. There is increasing pressure on universities to deliver social and economic impact in an increasingly market‐driven and metric‐driven environment. In the UK context, increasing financial pressure has led to both an escalation of student fees and constrained wage growth for faculty. In contrast, most Vice Chancellors have secured substantive pay packages raising concerns that regulatory failures may be contributing to the rise. We show that Vice Chancellors use their internal power within organisations to extract a disproportionate amount of the value created by the institution. However, we encountered much diversity according to the quality of governance, highlighting the extent to which not only contextual but also internal dynamics drive wage inequality.     

Volatility of volatility is (also) rough

Using high-frequency data for major volatility indexes, we compute the volatility of volatility and show that its logarithm follows a fractional Brownian motion with Hurst parameter smaller than 1/2 thereby extending to the volatility asset class the recent findings obtained for the equity index markets. The results confirm that the volatility of volatility is a rough process and it possesses the long memory property. We also show that the correlation between the volatility and the volatility of volatility is positive, consistent with observations in the volatility option market. Lastly, a robustness check using volatility futures confirms the findings.     

Dynastic Inequality Compared: Multigenerational Mobility in the United States,the United Kingdom,and Germany

Using harmonized household survey data, we analyze long‐run social mobility in the United States, the United Kingdom, and Germany, and test recent theories of multigenerational persistence of socioeconomic status. In this country comparison setting, we find evidence against a universal law of social mobility. Our results show that the long‐run persistence of socioeconomic status and the validity of a first‐order Markov chain in the intergenerational transmission of human capital is country‐specific. Furthermore, we find that the direct and independent effect of grandparents' social status on grandchildren's status tends to vary by gender and institutional context.     

技术型企业过往绩效对团队创新行为的影响：关系冲突的中介效应

基于IMOI模型，引入具备动态特征的“过往绩效”概念，利用长三角地区101个项目导向型研发团队问卷数据，依据社会信息处理理论和归因理论探讨过往绩效对团队创新行为的影响效果与内在机制。结果发现，过往绩效与团队创新行为显著正相关，关系冲突在过往绩效影响创新行为路径中起部分中介作用，并且关系冲突的中介机制在中国“人情”文化背景下能得到更好的解释；进一步，团队内部的恶意归因倾向在这一过程中发挥着调节作用。研究结果有助于从新视角探索技术型团队创新行为诱发机制，对双创背景下技术型企业创新管理实践具有一定参考意义。     

Stochastic leader–follower DEA models for two-stage systems

Data envelopment analysis (DEA) is a non-parametric approach for measuring the relative efficiencies of peer decision making units (DMUs). In recent years, it has been widely used to evaluate two-stage systems under different organization mechanisms. This study modifies the conventional leader–follower DEA models for two-stage systems by considering the uncertainty of data. The dual deterministic linear models are first constructed from the stochastic CCR models under the assumption that all components of inputs, outputs, and intermediate products are related only with some basic stochastic factors, which follow continuous and symmetric distributions with nonnegative compact supports. The stochastic leader–follower DEA models are then developed for measuring the efficiencies of the two stages. The stochastic efficiency of the whole system can be uniquely decomposed into the product of the efficiencies of the two stages. Relationships between stochastic efficiencies from stochastic CCR and stochastic leader–follower DEA models are also discussed. An example of the commercial banks in China is considered using the proposed models under different risk levels.     

Performance and learning in an ambiguous environment: A study of cryptocurrency traders

We investigate the performance and learning ability of traders in an environment governed by ambiguity, such as the cryptocurrency market. Using a profit decomposition methodology, we find significant cross-sectional and temporal heterogeneity in performance. Traders do not learn to progressively increase the magnitude of returns; however, they are able to improve on their ability to realise profits as a mechanism of adaptation to survive through ambiguity. This adaptation increases as traders progress through their career. Moreover, we find evidence in support of the gambler’s fallacy. We argue that learning in ambiguous environments has limitations, allowing traders primarily to survive.     

中国省域科技特派员制度实施绩效评估

2016年5月《国务院办公厅关于深入推行科技特派员制度的若干意见》发布实施，但其实施效果如何有待验证。构建科技特派员制度实施绩效评估指标体系，利用改进熵值法和官方统计数据，对中国省域科技特派员制度实施绩效进行实证评估，并对评估结果进行聚类分析。结果表明，中国大多数省份科技特派员制度实施绩效水平较低；根据实施科技开发项目、形成利益共同体、服务农民情况、推广服务和扶贫成效5个绩效评估维度，可以将中国内地31个省份划分为5种类型；即使是总绩效水平较高的地区，在科技特派员制度实施绩效方面也存在一些短板。
