数字化时代,制造企业通过组织模块化设计提升服务创新绩效成为服务化转型的重要途径,然而关于组织模块化能否以及如何提升制造企业服务创新绩效的研究还很缺乏.本研究从组织信息处理理论出发,探讨组织模块化发挥作用的内在机制.通过对285家制造企业的问卷调查发现:(1)组织模块化设计有助于提升制造企业服务创新绩效;(2)大数据分析能力在组织模块化和制造企业服务创新绩效之间具有中介作用;(3)组织敏捷性完全中介组织模块化和制造企业服务创新绩效的关系;(4)存在组织模块化-大数据分析能力-组织敏捷性-制造企业服务创新绩效的链式中介效应;(5)环境竞争性正向调节大数据分析能力和制造企业服务创新绩效的关系,表明随着环境竞争程度的提高,大数据分析能力对制造企业服务创新绩效的作用显著增强;(6)环境竞争性对组织敏捷性与制造企业服务创新绩效之间关系的调节作用不显著,然而无论环境竞争程度如何,提高组织敏捷性都能够正向影响制造企业服务创新绩效.本研究深化了组织模块化及其作用和优势的研究,并为数字时代制造企业组织架构创新、服务化转型等提供了借鉴.  相似文献

平台与互补商的协同专业化对于创新生态系统的构建具有重要作用.然而,平台企业与互补商可能各自具有冲突的或互补的制度逻辑,它们彼此要实现协同创新的目标,就必然在达成协作共识的过程中形成主导型制度逻辑,进而规范双方的创新活动与行为.但是,这种主导型制度逻辑如何产生?它们的作用机制是什么?过去的研究还很少涉及这类问题.本文通过OPPO的案例研究,结果表明:(1)平台与一般互补商合作时,平台的谈判能力相对较强,平台的制度逻辑占据主导地位;(2)平台对瓶颈互补商具有较强的依赖时,互补商拥有较强的谈判能力,平台在两者的合作中会选择妥协,此时互补商的制度逻辑占主导地位;(3)平台与瓶颈互补商的关系是双向依赖时,两方合作形成的制度逻辑是混合逻辑;(4)面对强大的外部制度压力时,平台与互补商的合作会形成或遵循新的制度逻辑.  相似文献

Hypertension and its related complications could be a major threat issue for cardiopathy and stroke. Effective prevention and control can decrease the incidence rate of complications in hypertension. Based on the medical data of 3062 patients with cardiovascular and cerebrovascular diseases from 2017 to 2018 in a grade-A tertiary hospital in Shanghai, the study identified the risk factors of hypertension complications by text mining. On this basis, the K2 algorithm based on the improved particle swarm optimization was proposed to optimize the structure of the Bayesian network (BN) by establishing a multi-population cooperative search mechanism. Then the optimized BN was used to analyze and predict the incidence rate of hypertension complications. Results indicate that the major indicators of accuracy, sensitivity, specificity, and AUC have been improved, and the proposed algorithm is superior to the common data mining algorithms such as the back propagation neural network and the decision tree. Through the proposed model and algorithm, the high-risk factors were identified and the occurrence probability of hypertension complications was predicted, which could provide the personalized health management guidance for hypertensive patients to prevent and control hypertension complications.

外汇储备通过传导机制对国内金融部门产生影响,研究外汇储备变化对金融稳定的影响是国家金融安全的重要内容。本文选取中国、巴西、俄罗斯、印度和南非五个"金砖国家"作为新兴市场国家的典型代表,采用Johansen协整检验和Bayesian向量自回归建模方法,实证研究外汇储备变化与金融脆弱性的关系。研究表明,不管从长期还是短期来看,外汇储备变化量增加会提高金融脆弱性指数,帮助国家应对短期经济波动,因此,增加外汇储备有助于国内金融部门稳定,抵御经济危机。  相似文献

中国居民代际收入流动性的变化趋势及影响机制研究   总被引:1,自引:0,他引:1  
杨沫  王岩 《管理世界》2020,(3):60-75
基于1989~2015年共计10轮CHNS数据,本文采用代际收入弹性和代际收入秩关联系数双重测度指标对我国居民代际收入流动性进行了测算,发现代际收入流动性在1991~2004年期间基本保持稳定,2004年以后呈现出不断上升的变化趋势。基于收入分组视角的研究发现,各收入组2004年以后代际收入阶层固化程度均有所降低,但高收入组和低收入组的固化程度远高于其他各组,中等收入群体是目前我国保持较高代际收入流动性的主要动力来源。从城乡差异视角看,受大规模农村劳动力向城镇流动的影响,2000年后农村家庭的代际流动性显著提升,且持续高于城市居民的代际流动性。进一步,基于人力资本分析框架对我国代际收入传递机制进行了探究,发现父亲的非教育因素在代际收入传递中起到主导作用。受整体社会制度环境不断改善的积极影响,2004年以后非教育传递机制不断减弱,对代际收入流动性的提升起到较大助推作用;而受高等教育扩张政策的影响,教育因素在2004年左右一定程度上削弱了代际收入流动性。  相似文献

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.  相似文献

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.  相似文献

Emergency material allocation is an important part of postdisaster emergency logistics that is significant for improving rescue effectiveness and reducing disaster losses. However, the traditional single‐period allocation model often causes local surpluses or shortages and high cost, and prevents the system from achieving an equitable or optimal multiperiod allocation. To achieve equitable allocation of emergency materials in the case of serious shortages relative to the demand by victims, this article introduces a multiperiod model for allocation of emergency materials to multiple affected locations (using an exponential utility function to reflect the disutility loss due to material shortfalls), and illustrates the relationship between equity of allocations and the cost of emergency response. Finally, numerical examples are presented to demonstrate both the feasibility and the usefulness of the proposed model for achieving multiperiod equitable allocation of emergency material among multiple disaster locations. The results indicate that the introduction of a nonlinear utility function to reflect the disutility of large shortfalls can make the material allocation fairer, and minimize large losses due to shortfalls. We found that achieving equity has a significant but not unreasonable impact on emergency costs. We also illustrate that using differing utility functions for different types of materials adds an important dimension of flexibility.  相似文献

本文基于社会嵌入的视角,探讨了离岸服务外包业务中发包方与接包方的文化差异与目标差异对客户满意的直接影响,进一步关注了接包方的顾客导向、专项投资和派驻代表等三种机制对上述关系的调节作用。通过对133个接包方企业的问卷调查进行实证分析,本文发现文化差异与目标差异对客户满意的实现确有阻碍作用,而专项投资对两种差异的负向效应均有缓解作用,顾客导向和派驻代表分别只对减缓文化差异与目标差异的负向效应有效。这些发现为接包方克服与发包方之间的差异,提高客户满意从而在离岸服务外包市场上获取更大份额提供了重要借鉴。  相似文献
