服务型领导对员工主动性顾客服务绩效的影响——基于社会交换与社会学习理论双重视角

文章以社会交换理论与社会学习理论为基础,以工作投入为中介和人际友好敏感性为调节,基于一个被调节的中介模型探索了服务型领导对员工主动性顾客服务绩效的影响机制。通过3个时间段11家酒店222份领导-下属配对问卷调查,研究发现:(1)服务型领导对员工主动性顾客服务绩效有显著的正向影响;(2)员工工作投入在服务型领导与主动性顾客服务绩效之间发挥着部分中介作用;(3)员工人际友好敏感性对服务型领导与员工工作投入之间的关系具有显著的正向调节效应,即员工人际友好敏感性越高,二者之间的正向关系越强;(4)员工人际友好敏感性对服务型领导与员工主动性服务绩效之间通过工作投入的间接关系具有显著的正向调节作用,即员工人际友好敏感性越高,这种正向的间接关系就越强。甘肃省教育厅课题“‘一带一路’战略背景下甘肃省旅游业服务质量评测体系及服务效益研究”(2015B-135)资助~

企业创新、生命周期与聚集经济

企业的创新会受到其所处生命周期阶段及所在城市中其它企业在地理上集聚而产生的外部经济的影响。本文运用2007年中国规模以上工业企业数据进行实证研究，发现企业的创新在生命周期不同阶段会受益于不同的聚集经济：新生或年轻企业的创新更多地受益于产业多样化带来的雅各布外部经济，成熟企业的创新则更多地受益于产业专业化带来的马歇尔外部经济。本文为文献中关于马歇尔外部性还是雅各布外部性更促进企业创新争论提供了新的经验检验证据，且为Duranton 和 Puga（2001）的理论模型提供了实证验证。：Firms’ innovation will be affected by its age and the cluster of other firms in the same geography unit. In this paper, we employ the micro-level Chinese manufacturing data to analyze the relationship of firms’ innovation and economies of agglomeration from the perspective of firm life cycle. The empirical results suggest that new or young firms are more likely to benefit from Jacobs externalities, and mature or old firms may benefit more from Marshall Externalities. We solve the long existing dispute on which externality improves firms’ innovation, and we are among the first few papers that provide empirical evidence for Duranton and Puga (2001) paper.本文被《经济学》接受拟发表
