Leveraging middle managers’ brokerage for corporate entrepreneurship: The role of multilevel social capital configurations

Building on recent efforts to bring a socio-political perspective to social capital research, we develop and test a multilevel framework that explains why middle managers who occupy brokerage positions differ in their ability and willingness to engage in entrepreneurial behavior. More specifically, we provide a contextualized understanding of the links among middle managers' brokerage, their political-support ties, and their personal initiative. Results derived from data on 383 middle managers and 72 top managers in 34 business units indicate that political-support ties with top managers strengthen the relationship between middle managers’ brokerage and personal initiative. However, this positive effect depends on the social capital resources available in the focal business unit. It is attenuated in business units with a supportive and trusting social context and amplified in business units with high levels of internal connectedness. By uncovering these incompatibilities and complementarities, our study demonstrates the value of accounting for different social capital configurations and the interplay of their inherent social capital resources when examining the effects of brokerage on corporate entrepreneurship.     

The relationship between presenteeism and job satisfaction: A mediated moderation model using work engagement and perceived organizational support

Research on presenteeism has largely focused on its prevalence, determinants and consequences on the health of both employees and organizations. To date, few studies have examined the influence of presenteeism on workers’ attitudinal and motivational responses. Based on the Effort–Recovery Theory, this study evaluates the mediating effect of work engagement in the relationship between presenteeism and job satisfaction. Building on previous work, this study also proposes to consider perceived organizational support as a moderator of the work engagement–job satisfaction relationship. Presented in the form of a mediated moderation model, the results of bootstrapped regression analyses show three main results. First, presenteeism is negatively associated with work engagement and job satisfaction. Secondly, work engagement is one of the factors through which presenteeism influences job satisfaction. Thirdly, perceived organizational support moderates the association between work engagement and job satisfaction so that, at a low level of work engagement, feeling supported by the organization makes a difference on job satisfaction. Overall, this research is part of the limited number of studies that have focused on the interplay existing between presenteeism and its consequences in terms of job attitudes.     

“政策领域-时间维度”双重视角下新能源汽车产业政策央地协同研究

本文以2009—2018年间中央及地方（以北京市等四个地区为例）颁布的263项新能源汽车产业政策为研究样本,从实施领域角度,将产业政策分为财税支持、行业规范、规划引导、监督保障、其他措施等五类,经政策分解,将政策片段与新能源汽车产业链五个环节进行匹配;在此基础上,测度不同时期产业政策央地总体协同度与政策实施领域间的协同度,并通过逐步回归法,确定影响政策协同的各政策效力指标灵敏度。研究表明："中央-北京"和"中央-深圳"的政策措施协同趋势基本一致,产业价值链各环节发展较均衡,而"中央-上海"和"中央-江苏"的政策措施协同趋势基本一致,存在"重使用、轻研发、轻市场"等失调现象;四地区与中央政策措施的协同差异主要体现在研发、生产和回收环节,提升"政策引导"和"保障措施"指标的政策效力有助于提升央地协同水平。根据政策分析,未来政策制定需从优化中央政策推广方式和加强监管保障等政策措施着手,根据产业链不同环节状况适时调整政策措施。     

财政分权、产业结构调整与绿色全要素生产率——基于环境污染门槛效应的视角

基于财政分权下政府与产业结构调整的策略博弈,从理论模型分析了政府产业引导与产业自身调整间的非合作博弈的发生、造成产业结构调整在绿色全要素生产率上的异质化效应,并应用2004—2017年间中国省级面板数据,采用动态面板门槛模型进行了实证检验。研究结果表明:当环境污染程度较低时,财政分权的施行将有助于产业结构调整带动绿色全要素生产率提升;当环境污染程度较高时,财政分权的施行将不利于促进产业结构调整带动绿色全要素生产率提升;财政分权主要通过税收竞争与财政环境补贴和支出双重路径影响产业绿色全要素生产率的提升。借此,对在区域财政分权背景下动态调整区域财政体制与产业绿色发展转型提出了相应的建议。     

要素禀赋、农户分化与农业价值链技术选择偏向

基于551份猕猴桃种植户调研数据,通过聚类分析方法将猕猴桃种植户分成发展型、规模种植型、劳动力富裕型三类,实证检验种植户类型对有机肥施用、新品种采纳、猕猴桃网络销售三个价值链技术活动选择的异质偏向性,分析农机补贴、产业组织检测、技术培训三个组织支持变量的调节效应。结果发现：发展型对于三个价值链技术活动及其联合采纳的选择偏向性高于其他类型,劳动力富裕型种植户对价值链技术活动的选择偏向性低于其他两个类型种植户。三个组织支持变量对同一类型种植户参与不同价值链技术活动以及不同类型种植户参与同一价值链技术活动的影响具有异质性。因此,针对不同类型价值链技术活动参与特征以及组织支持调节作用提出相应的政策建议。     

自致努力、政府扶持与水电工程移民生计资本累积

基于2019年三峡库区移民生计专题调查数据,采用OLS、PSM以及分位数回归模型比较分析了移民生计资本的变化以及自致努力与政府扶持对移民生计资本的影响效应。研究发现：三峡水电工程移民搬迁显著减少了移民生计资本,且对外迁安置移民生计资本的负向影响比就地安置移民更大;自致努力与政府扶持均能显著增加移民生计资本,但政府扶持对移民生计资本的回报率显著低于就近安置地原居民,自致努力对生计资本的回报率在移民与就近安置地原居民中没有显著差异,该结论没有受到安置方式的影响;进一步研究还发现,随着生计资本分位点的提高,自致努力和政府扶持对移民生计资本的提升效应呈现递增趋势,这会扩大移民之间的生计资本差距。据此提出依据不同参照群体完善移民生计资本恢复和发展的评价制度,建立自致努力与政府扶持相结合的移民生计资本培育路径,同时加快缩小移民内部群体间生计资本差距等建议。     

代际支持对流动老年人生活满意度的影响：自我效能感和心理弹性的序列中介作用

以654名流动老年人为调查对象,通过问卷调查探讨不同的代际支持水平对流动老年人生活满意度的影响及自我效能感和心理弹性的序列中介作用。结果表明,代际支持、生活满意度、自我效能、心理弹性四因素之间两两显著相关。自我效能感与心理弹性在代际支持与生活满意度之间均有中介效应,中介效应值为0.198和0.078,且两者在代际支持与生活满意度之间具有序列中介效应,中介效应值为0.107。结果提示,代际支持通过自我效能感和心理弹性的链式中介效应,对流动老年人生活满意度产生直接的正向预测作用。     

Optimization Model and Algorithm for Crew Management During Airline Irregular Operations

Airline irregular operations have long been a realm where human experience and judgement are the most important tools to utilize. Crew management during irregular operations is usually the bottleneck of the whole system-recovering process due to complicated crew schedules and restrictive crew legalities as well as the size and scope of the hub-and-spoke networks adopted by major carriers. A system-wide multi-commodity integer network flow model and a heuristic search algorithm for the above purpose are presented and discussed in this paper. The computational experiences show that the algorithm is efficient enough to solve problems of realistic size and also has the flexibility to accommodate practical business requirements.
