发展我国民营企业之对策探讨

民营企业是我国国民经济的重要组成部分,在我国经济建设中发挥着重要作用。但是在民营企业的发展过程中,出现了许多阻碍民营企业进一步发展,甚至导致民营企业出现危机的问题。针对上述问题,文章进行了深入分析并提出了相应的对策。     

探析汽车企业如何在全球范围内合理化供应链的理论基础

借鉴供应链管理中的系统思想、需求驱动思想、合作共赢思想、同步运作与动态重构思想,分析研究汽车企业在全球范围内合理化供应链的理论基础:供应链作为一个具有特定功能的有机整体,是基于一定的市场需求而产生和变化的;用户的需求及其变化是企业合理化供应链和供应链动态可重构的驱动源;供应链各成员企业之间基于"竞争-合作-协调"机制,以分布式企业集成合作、协调同步运作为保证,在价值增值链上达到共赢的目标。

我国股票市场的系统流动性实证研究

1997年的亚洲金融危机显示出个股的流动性受到市场因素的强烈影响,市场微观结构的研究开始更多地关注市场的系统性因素.本文以上海证券交易所全部A股的日交易数据为样本,证实了我国大陆股市存在系统流动性,与美国、香港股市相比,这一因素的影响更显著;根据流通股每年的流通市值分组检验,发现我国大陆股市与香港股市相似,存在着"倒U"形态的规模效应;与发达股票市场不同,我国股市系统流动性的显著性比例与流通市值无明显的单调关系.     

Effects of work–family and family–work conflicts on flexible work arrangements demand: a gender role perspective

In recent years, a growing number of firms have adopted flexible work arrangements (FWAs) to help managers balance their work–family demands. Based on a sample of 1336 married managers in Korea, we found that work–family conflict increased the FWAs demand more for female managers than for male managers. When facing work–family conflict, the absence of family-supportive supervision increased the demand for FWAs, particularly among female managers. No such effect was found for family–work conflict. In addition, having a female supervisor led to an increased demand for FWAs from company managers. These results suggest that firms should pay close attention to gender difference and supervisory roles in predicting the demand for FWAs to alleviate work–family conflicts.     

Childcare Assistance: Are Subsidies or Tax Credits Better?

We evaluate price subsidies and tax credits for childcare. We focus on partnered women's labour supply, household income and welfare, demand for childcare and government expenditure. Using Australian data, we estimate a joint, discrete structural model of labour supply and childcare demand. We introduce two methodological innovations – a more flexible quantity constraint that total formal and informal childcare hours are at least as large as the mother's labour supply and the explicit inclusion of maternal childcare in the utility function as a proxy for child development. We find that tax credits are more effective than subsidies in terms of increasing average hours worked and household income. However, tax credits disproportionately benefit wealthier and more educated women. Price subsidies, while less efficient, have positive redistributional effects.     

政府补助、保险支付与老年临终照料成本——基于2002-2014年CLHLS死亡人口追踪数据的分析

为应对日益增大的老年人照料压力,我国各地试点通过政府补助或社会保险支付的方式满足老人的照料需求。基于2002-2014年CLHLS死亡人口追踪数据,文章用两部分模型、Heckman选择模型和结构方程模型,分析了政府补助、保险支付对老年临终照料直接成本和总成本的影响及其中介机制。研究发现,老年临终照料服务由保险支付的直接成本和总成本都比家庭支付明显更高,政府补助的直接成本比家庭支付更高,保险支付的直接成本比政府补助更高。保险支付和政府补助对照料成本影响的机制存在差异,保险支付主要通过收入效应对照料成本产生显著影响,但替代效应也发挥了中介作用,政府补助则主要通过替代效应对照料成本产生显著影响。文章的研究结论具有重要的政策含义。我国发展长期护理保险,应合理界定政府、市场、社会和家庭对老年人的照料责任,并明确长期护理保险的有限责任,尽量降低可能的收入效应和替代效应对照料成本的影响。     

Emotional intelligence,job insecurity,and psychological strain among real estate agents: a test of mediation and moderation models

We develop two models of the relationships between emotional intelligence (EI), job insecurity, and psychological strain. The moderation model suggests that EI reduces psychological strain by helping individuals cope with job insecurity when it arises. The mediation model suggests that EI reduces psychological strain by enabling individuals to conserve resources, thereby reducing their experience of job insecurity. Our results, based on a sample of 232 real estate agents, show that job insecurity mediates the relationship between EI and psychological strain. Contrary to what the moderation model suggested, the positive relationship between job insecurity and psychological strain was found to be stronger when EI was higher. Overall, the results provide more nuanced insights into the role of EI in psychological strain.
