This paper examines how movie producers recruit directors in the preproduction phase as mutual choices in a two-sided matching model. It conceptualizes that movie attributes and filmmaker characteristics determine the matching outcomes (“who directed which movie”) and in turn indirectly affect movie box office. We exploit a dataset of 4,807 feature films from 1990 to 2010 to examine empirically the complementarities between the movie/producer side and the director side in terms of movie budget, filmmaker track records and social relations. A series of simulations suggest that social relations facilitate positive assortative matching. Further simulation analyses are conducted to quantify the financial implications of movie–director mismatches, as well as the indirect effects of production budget and producer characteristics. The simulation results show that: a) the financial implications of having a mismatched director can be substantial; and b) the indirect effect of production budget and producer characteristics affect movie box office in an interactive manner. These findings can help filmmakers to better understand the financial impacts of movie–director choices and make more informed decisions at the early phase of preproduction. 相似文献

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. 相似文献

当前经济社会形势下,家族企业接班人肩负着带领企业跨代创业的使命。然而,“人在江湖,身不由己”,接班人跨代创业的行为动机受到高管团队约束。基于此,根据社会嵌入理论,从认知、关系、结构三维度构建接班人嵌入到高管团队对经营多元化影响的分析模型,并对其中的作用机制进行探讨。实证研究表明,接班人和高管团队在认知嵌入上的教育背景同质性、在关系嵌入上的亲密度以及在结构嵌入上的中心化均与经营多元化呈正相关;信任在接班人和高管团队嵌入性与经营多元化关系中发挥部分中介作用。进一步分析发现,父代保守战略嵌入到高管团队中一定意义上不利于企业转型。结论表明,家族企业接班人跨代创业的行为动机受到社会嵌入的影响。 相似文献

The spread of the COVID-19 pandemic has resulted in the launch of contactless delivery services. This research integrates resource matching, service quality evaluation, and perceived value theories to explore the factors that promote the use contactless delivery services. The data was obtained through questionnaire surveys, and research hypotheses were verified through the structural equation modelling approach. With the exception of convenience, the results show that privacy, reliability, security, and flexibility have a significantly positive effect on consumers' intention to use “contactless” delivery services through consumers' perceived value. This study contributes to the literature by introducing theoretical frameworks from various paradigms and enriches the academic research on existing theoretical structure models. It also helps optimize resource allocation and realize the social environment related to coexisting with the COVID-19 pandemic. 相似文献

为了解决宏蜂窝与飞蜂窝构成的两层异构网络上行干扰与资源分配问题,提出了一种在认知型飞蜂窝的双层异构网中结合子信道分配和功率控制进行资源分配的框架。通过对异构网中跨层干扰问题进行分析与建模,将求解最优子信道分配矩阵和用户发射功率矩阵作为干扰管理问题的解决方法。模型中认知型飞蜂窝网络子信道和飞蜂窝网络用户构成非合作博弈,双方利用效用函数最优值进行匹配,构成初始信道分配矩阵;再由接入控制器根据接入条件从初始信道分配矩阵中筛选用户,并优化接入用户的发射功率矩阵,得到最优子信道分配矩阵和功率矩阵。仿真结果表明,优化框架提高了双层异构网络中飞蜂窝网络用户的吞吐量和接入率,降低了异构网中跨层干扰。 相似文献

The success of the operations of formal and informal financial institutions (IFIs) hinges on a high degree of trust. The pivotal role of trust warrants careful analysis regarding its formation in these financial institutions. Using the case of Cameroon, the paper interrogates trust development between formal financial institutions and their clients, and between IFIs and their members. Trust formation occurs via certain cognitive trust-building processes: calculative, prediction, intentionality, capability, and transference processes. The paper argues that trust formation through these processes is predicated upon cultural values and beliefs. It is precisely because of cultural norms that traditional leaders play a role in ensuring that loans granted by formal financial institutions are repaid, thereby serving as principal actors in the functioning of financial capitalism in rural areas. The interplay between culture and financial institutions reconfigures the financial architecture in rural zones. Culture creates a social relational anthropology that is significant for how financial institutions operate. 相似文献

关于合作关系对合作创新的影响,现有研究大多局限于单一的社会网络视角,对网络层次的关系特征如何通过双边层次的关系质量影响技术创新模式的过程欠缺机理性认识。结合社会网络、社会资本和知识转移理论,分析网络联结强度、企业间信任以及技术创新模式三者间关系。利用327份来自全国多地的制造及高新技术企业数据,采用结构方程模型检验方法对研究假设进行检验。结果表明:相对于经济型信任,强联结会带来更多情感型信任;情感型信任更有利于渐进式创新,经济型信任更有利于突破式创新;联结强度对渐进式创新的作用是通过情感型信任传递的,而联结强度对突破式创新的作用是通过经济型信任传递的。 相似文献

This study examines whether and how competitive experience affects gender difference in the preferences for risk and trust as well as academic performance. By utilizing the provincial differences in college admission rates as an indicator of competitive experience for students, we assess its relationship with gender difference in risk preference, trust preference, and academic performance. We find that females from provinces with lower college admission rates are more risk averse and less trustful, and perform better in more competitive environment, compared with their male counterparts. Our study suggests that observed gender differences may partially reflect the effects of schooling environment rather than inherent gender traits. 相似文献

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature. 相似文献

ABSTRACTAs service-oriented computing is commonly used in industrial systems to deal with the continually changing business environment, matching processes with existing services becomes one of the most important phases in constructing, integrating and optimizing information systems. The precision of semantic service matching becomes a critical factor in ensuring the correctness of functionalities in system processes. However, the dependability of semantic service matching cannot be warranted in complex contexts. To improve semantic service matching for industrial systems, a context-based semantic service matching approach named ‘Process-Based service MatchMaker’(PBMM) is proposed in this paper. It selects the suitable services for the process from candidate services through taking the dependencies of related services process into consideration. 相似文献
