Transitioning from catch‐up in production to catch‐up in innovation capabilities is essential to emerging market firms (EMFs) achieving internationalization and a competitive advantage. While some EMFs are now positioned among the world's most advanced firms, many struggle to become independent innovators. Thus, understanding how EMFs can develop internal absorptive capacity and progress towards catching up in innovation capabilities remains important. Our study seizes this research opportunity and develops a network‐based explanation of catch‐up, which complements existing technological and organizational explanations. Specifically, we address the question of ‘How does the orchestration of collaborative networks enable EMFs to catch up in production and innovation capabilities?’ by describing an important yet under‐researched process of strategic network orchestration and showcasing the dynamic interdependencies between network orchestration and organizational learning. Our study provides a detailed account of Chinese high‐speed train (HST) development from 1990 to 2020 and opens the possibility for future research on network orchestration in emerging market contexts. This provides EMF managers with a set of actionable network orchestration mechanisms that can be used when designing and purposefully managing their strategic nets of domestic and foreign partners.  相似文献

This study draws on survey data from 205 family mediation service users concerning their satisfaction with the outcomes of mediation to address two research questions: (a) how satisfied are service users? and (b) what factors account for users' satisfaction with the outcome of child custody arrangements and the allocation of finances and property? Overall, users' level of satisfaction with outcomes was high. While the mediation process explained a significant variance in satisfaction with the outcomes for child custody and for finances and property, the mediator's perceived professional competence did not predict user satisfaction with the outcomes for either issue. This study contributes to our knowledge on the significance of mediators' process skill, specifically their calm and clear responses to the socioemotional needs of the mediated parties, on the service outcomes for both types of dispute. The implications for mediation training are discussed.  相似文献

社会生物学依循"威尔逊阶梯"的总体思路,运用广义适合度、进化稳定策略、博弈论分析等概念或方法来刻画与界定人性.通过细致分析,基切尔揭示了社会生物学在探求人性过程中犯下的一系列方法论谬误,并在研究结论中混杂了大量迎合新右翼政治立场的阶级偏见、种族偏见与性别偏见.基切尔试图表明,尽管人性在基因制约下有其局限性,但人性依旧可以在这种约束条件下得到重塑与改进.社会生物学对人性固定性的仓促论证,并不足以说服人们放弃让人类社会变得更加公正与平等的种种努力.  相似文献

《民法典》侵权责任编对原有通知删除规则进行了科学修正,但事前保护缺位与事后救济程序失范的问题仍然存在。随着网络服务提供者完成角色转型和技术升级,其作为网络侵权风险的控制者和参与者,有必要且有能力承担未通知阶段的主动预防义务和已通知阶段的证明材料审查义务,以弥补著作权保护和用户利益保护的漏洞。双重注意义务应分别与网络服务提供者对侵权危险的预期和控制能力以及材料审查能力相适应。未通知阶段之注意义务以技术措施为主要履行方式,其注意标准的认定应综合考量技术水平、服务类型、内容介入程度、是否直接获取收益等要素,未尽该注意义务仅为过错认定的考量因素而非唯一标准,并不必然导致侵权责任。已通知阶段之注意义务仅限于对提交的证明材料进行形式审查和有限的实质审查,尽到此注意义务的,可以免于承担侵权责任。  相似文献

We investigate state-dependent effects of fiscal multipliers and allow for endogenous sample splitting to determine whether the U.S. economy is in a slack state. When the endogenized slack state is estimated as the period of the unemployment rate higher than about 12%, the estimated cumulative multipliers are significantly larger during slack periods than nonslack periods and are above unity. We also examine the possibility of time-varying regimes of slackness and find that our empirical results are robust under a more flexible framework. Our estimation results point out the importance of the heterogenous effects of fiscal policy and shed light on the prospect of fiscal policy in response to economic shocks from the current COVID-19 pandemic.

Abstract

China is home to approximately 245 million rural-to-urban migrant workers. The influx of migrants into urban areas has posed various challenges for local social service systems. Recently, increasing number of community services have been developed to meet the growing service demands from the migrant population. However, whether increase in community service use results in improved wellbeing among migrant workers remains critically unexplored. As such, this study examines the role of community service use in migrant workers’ life satisfaction and the potential mediating effect of identity integration in Shenzhen, China. Bootstrapped models were adopted to examine relationship among variables. Drawing from a sample of 1,087 rural-to-urban migrant workers, we found that community service use is positively correlated with both identity integration and migrant workers’ life satisfaction. Moreover, identity integration served as a partial mediator between community service use and life satisfaction. The mediating effect of identity integration was found to increase with age. This study highlights that diverse services should be implemented to address divergent needs of migrants in different age groups. Community service can also serve as a vehicle to foster integration among migrant workers in host communities, especially for older age groups. Future studies may further investigate the relationships between community social capital, community social support, quality of community-based organization and frequency of service use so as to optimize the life satisfaction of migrant workers.  相似文献

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.  相似文献

通过应用中国城市家庭消费金融调研数据,本文系统的实证检验了改进后的金融知识指标、经济学专业、金融学专业以及家庭理财规划等因素对家庭各项财富积累的影响,并通过使用合适的工具变量进行两阶段估计,验证了这种正向影响的稳健性。此外,实证结果中家庭理财规划以及理财规划时间跨度的正向边际效应表明,理财规划可能是金融知识差异影响家庭财富积累的重要机制。研究结论有利于更准确地理解居民金融知识差异对于家庭福利,特别是退休福利的影响。  相似文献
