Economic Development and Women's Labor Force Participation in India

India has experienced steady economic growth over the last two decades alongside a persistent decline in women's labor force participation (LFPR). This paper explores the relationship between economic development and women's labor supply using state-level data spanning the period 1983–4 to 2011–2. While several studies suggest a U-shaped relationship between development and women's labor force participation, our results suggest that at the state level, there is no systematic U-shaped relationship between level of domestic product and women's LFPR. On examining the relationship between the structure of the economy and women's economic activity, we find that it is not economic growth but rather the composition of growth that is relevant for women. Further, our results suggest that aggregate changes in the proportion of women in the workforce can be mostly attributed to the movement of the workforce across sectors rather than changes in the proportion of women workers within a sector.

环境规制影响工业行业生产率的实证研究

采用我国36个工业行业2001-2010年的面板数据,运用DEA-Malmquist指数方法测算出分行业全要素生产率,考察环境规制对生产率的直接和间接影响。在行业分组基础上,进一步考察环境规制对生产率影响的行业差异性。结果显示:1环境规制强度与工业行业生产率存在显著的非线性U型关系,即随着环境规制强度的增加,生产率呈现先下降后上升的趋势;2环境规制会通过利润率和企业进入两个途径对行业生产率产生间接作用;3相对于污染型行业,清洁型行业会更早的跨越U型拐点。并提出以下政策建议:我国应该适度加强环境规制的强度;考虑到行业的差异性,针对污染型行业应该制定更为严格的环境规制政策。     

Population Aging and Housing Consumption： A Nonlinear Relationship in China

Mass migration of rural workers to cities will inevitably increase urban housing demand. However, the scale of vacant urban housing will increase in future as a result of the population aging and the rising number of empty nesters. Therefore, demographic transition may not only increase housing demand, but also increase housing supply. Using an overlapping generations model, the present paper investigates＇ the impact of demographic transition on housing consumption. We find that there is a nonlinear relationship between the elderly dependency ratio and housing consumption in China. With the deepening of population aging, housing consumption will increase; when the elderly dependency ratio reaches a turning point, housing consumption will decrease. The turning point of the nonlinear curve also depends on population mobility. A greater degree of population mobility will result in a delayed turning point. Furthermore, the turning point of the nonlinear curve will emerge when China＇s elderly dependency ratio reaches a value of 32 percent in 2025. This means that over the next decade, China should continue to increase the level of housing supply,

领导-成员交换与员工离职倾向的U型关系研究

基于对领导-成员交换理论和员工离职过程模型的研究,通过在国内某电器连锁销售企业的实践调研,从实证角度验证了领导-成员交换和员工离职倾向之间在总体上表现为负显著相关,同时也通过阶层回归分析验证了在非常高质量的领导-成员交换关系中领导-成员交换与员工离职倾向两者间可能存在着U型关系。组织中的领导者应着重从情感层面强化员工对组织的承诺感,并加强对员工职业生涯规划的辅导,努力降低下属的离职倾向。

自重构机器人协作功能的规划与实现

自重构机器人是一组具有重构功能的自主微小型机器人团队,具有较强的灵活性和隐蔽性,在军事侦察、灾情救助、空间作业等场合具有广阔的应用前景。因单个机器人的环境信息感知能力、越障能力等都较差,使微小型机器人的应用受到了很大制约。通过自重构机器人协作决策、协作定位、地形侦察、重构与越障等协作功能的规划并实现,有效地增强机器人系统适应动态环境的能力,提高多机器人系统的整体性能,拓展了机器人的应用领域。
