子女照料、家庭负债与已婚女性就业——基于Becker家庭决策模型的微观实证

子女照料与家庭负债对已婚女性的就业选择具有重要影响。为此,在Becker家庭决策模型基础上,建立资产负债约束下已婚女性“子女照料—闲暇—就业”效用最大化决策模型,利用2016年CFPS数据分析发现：子女照料对已婚女性就业概率及周工作时间存在负向影响,且家庭的银行负债对子女照料与已婚女性就业的关系存在负向调节效应。因此,在鼓励女性生育的政策背景下,政府需要综合考虑子女照料负担与家庭负债约束,制定更加有效的已婚女性就业保障政策。

Workgroup Salary Dispersion and Turnover Intention in China: A Contingent Examination of Individual Differences and the Dual Deprivation Path Explanation

The present study generalizes previous pay dispersion research to the Chinese context by examining the cross‐level relationship between workgroup salary dispersion and employee turnover intention contingent on individual differences. Field survey data including annual objective salary and self‐reported attitudes among 370 Chinese employees in 51 organizational workgroups supported our cultural predictions by showing that the relationship between workgroup salary dispersion and turnover intention was positive only among employees with higher rather than lower levels of Chinese traditionality and among those with lower rather than higher salary levels. Furthermore, the results of mediated moderation analyses suggest that a dual‐deprivation path model can explain the above relationships. We discuss the theoretical, cultural, and practical implications of these findings for organizations. © 2015 Wiley Periodicals, Inc.     

Subnational institutional contingencies and executive pay dispersion

This paper investigates the impact of subnational institutional contingencies on executive pay dispersion structure and the relationship between pay dispersion and firm performance. Using executive compensation data on Chinese listed firms between 2000 and 2011, we find that executive pay dispersion is significantly lower in state-owned enterprises (SOEs), while is significantly higher in cross-listed firms and to a smaller degree in firms located in developed regions. There is also evidence that executive pay dispersion is smaller during the voluntary compensation disclosure period. After controlling for endogeneity of pay determination, we find that executive pay dispersion is positively associated with firm performance. In addition, the positive link between executive pay dispersion and firm performance is stronger in non-SOEs than in SOEs, and stronger in firms located in more developed regions than those not. Our findings are also robust to alternative measures of pay dispersion and firm performance.     

从出口扩张到对外贸易“换挡”:基于贸易结构转型的贸易与研发政策选择

在国内要素成本不断上涨和发达国家"再工业化"的背景下,我国对外贸易将从高速扩张,"换挡"到中高速增长的"新常态",对外贸易结构能否相应地实现转型升级、贸易与研发政策如何制定,值得深入研究。本文在纵向关联市场框架下构建理论模型,探讨在核心技术水平落后于发达国家的前提下,实现贸易结构转变的方式和条件,以及贸易结构转变前后的贸易和研发政策选择。本文发现,在进口中间产品的贸易格局下,我国实施研发补贴和出口补贴政策,可以实现贸易质、量增长的平衡;而在出口中间产品的贸易新格局下,我国仍然可以通过实施研发补贴和出口补贴政策,实现贸易质、量达成新的平衡。本文还发现,创新驱动发展是在贸易增速"换挡"的"新常态"下,实现出口结构转型升级和出口数量稳定增长的关键。     

旅游者人格特质与漂流体验偏好关系研究

以人格特质理论为依据研究漂流旅游者人格特质与漂流体验偏好之间的关系。对长沙市宁乡县沩山漂流和峡溪漂流游客进行抽样调查,经过实证分析证实：神经质、外向性、开放性及严谨性人格特质与漂流体验偏好均显著正相关;宜人性人格特质仅与舒心轻松漂流体验偏好显著正相关,与其他漂流体验偏好则没有相关关系。     

自然环境和人类社会的关系研究

人类社会和自然环境的关系是现代地理学研究的重要课题,也是当今社会发展探讨的问题,还是人类认识世界的永恒命题。对于人类社会和自然环境的相互关系,应建立人与自然和谐发展关系。     

How Affirmational versus Negational Identification Frames Influence Uniqueness‐Seeking Behavior

This research tested the proposition that consumers presenting under a negational identification frame are more likely to choose unique products than when they present themselves affirmationally. Study 1 demonstrated this main effect in a real‐choice setting. Study 2 underlined temporary accessibilities to one's desired (undesired) identities when an affirmational (negational) identification frame is adopted. Study 3 further demonstrated that identity valence interacts with identification frames in driving uniqueness‐seeking tendency. Additionally, this effect was found to be mediated by self‐other distinction in Study 4. The research implications for both the “what” and the “how” aspects of identity‐driven consumption are discussed.
