Effects of mentoring functions on receivers' organizational citizenship behavior in a Chinese context: A two-study investigation

This research examines the relationship between mentoring functions received by employees and their organizational citizenship behavior (OCB), and the moderating effects of perceived quality relationships with mentoring function providers in China. Results of Study 1 from a sample of 385 supervisor-subordinate dyads reveal that role modeling received by protégés positively relates to their OCB, and perceived mentoring relationship quality moderates the association between career support received and protégés' OCB. Moreover, nonprotégés and protégés who receive high levels of overall mentoring functions perform more OCB than protégés who receive low levels of mentoring functions. Results of Study 2 from 258 supervisor-subordinate dyads show that role modeling received by subordinates positively relates to their OCB directed at individuals (OCBI) and at the organization (OCBO) while career support received positively relates to OCBO. Additionally, leader-member exchange moderates the linkages of role modeling with OCBI and OCBO.     

Reducing land fragmentation to curb cropland abandonment: Evidence from rural China

Reducing land fragmentation can theoretically curb cropland abandonment, thus ensuring food security. However, few studies have quantified this relationship using large-scale survey data at the household level. This study adopts a two-way fixed-effects (TWFE) model to examine the effect of land fragmentation on cropland abandonment using nationally representative panel data from the China Rural Household Panel Survey (CRHPS). The panel data set contains 15,138 households across 29 provinces in 2017 and 2019. We find that land fragmentation has a significant and positive relationship with cropland abandonment. The mechanism analysis reveals that this relationship is due to high labor costs and difficulties in renting out the fragmented land. The heterogeneity analysis indicates that farmers with poor human capital and those living in non-plain areas are at a higher risk of abandoning their cropland due to land fragmentation. Furthermore, the association between land fragmentation and cropland abandonment tends to vary across different land rent-in scenarios. For instance, an increase in the number of plots in the case of land rent-in is not necessarily associated with cropland abandonment. These findings are conducive to correcting the underestimation of the role of land fragmentation in cropland abandonment, and their implications may be extended to various countries.     

中国人口地区分布现状及其历史变迁

根据 2 0 0 0年人口普查资料 ,分析了我国人口的地区分布特征及其在过去 70年中的变化过程。研究表明 :中国人口分布的地区差异大 ,人口分布的总格局是东密西疏。 70多年来 ,我国人口地区分布的总趋势是由东向西倾斜 ,全国人口分布的重心也向西北方向移动 ,但在不同的历史阶段上 ,人口地区分布的变化趋势各不相同。我国人口地区分布的集中程度在降低 ,人口的分布趋于“均匀化”

论我国电子商务物流体系的构建

与电子商务相适应的物流体系是由第三方物流和企业自营物流两部分组成,它是在现代物流的基础上采用供应链管理思想与方法、以现代信息技术为手段、以一体化物流为主要内容、以全面降低企业成本为目标,服务于电子商务活动的物流体系。由于我国物流发展的水平较低,不能与电子商务实现直接对接,所以我国第三方物流体系与企业自营物流体系的构建必须是符合我国国情的原则和策略。
