影响我国农民市场主体地位确立的制度因素

拥有自主产权是农民成为真正市场主体的必要条件,包括诸如组织制度、户籍制度、金融制度、社会保障制度等在内的产权支持系统是影响农民成为市场主体的充分条件。市场主体地位的高低在某种意义上是由经济实体在参与市场经济活动时所拥有的权利束决定的。推进农村经济市场化的过程就是加强农民市场主体地位的过程。进一步深化农村体制改革,从根本上消除不合理制度对农民的束缚,使农民成为真正的市场主体是解决当前“三农”问题的根本出路。     

商业银行利率风险计量模型及实证分析--非平移收益曲线条件下的随机免疫策略

传统的久期理论建立在收益曲线平移等严格假设条件上，因而其在实践中的有效性大大降低了。根据Markowitz（1959）等理论可推导出：资产价格的总风险包括收益的方差和全久期向量两部分；假若商业银行采取现金中性（cash neutrality）的资产交易策略，风险计量模型可转换为线性规划问题，从而可以构建基于利率风险最小化模型的随机免疫策略。也就是说，引入随机免疫的理念来替代经典的免疫理论，通过实证分析得出：无现金交易条件下的随机免疫策略能够降低利率风险。     

基于高频数据的深圳基金市场日内周期性研究

本文利用深市基金指数高频数据,采用Anderson和Bollerslev(1997)提出的弹性傅立叶回归(FlexibleFourierFormregression,即FFF回归)方法首次对深市基金市场进行了日内周期性的研究。通过对高频收益的定性分析,发现基金市场具有同股票市场相似的周期性,并对这一周期性进行了初步的理论解释。通过FFF方法,将该周期因子进行滤波处理以后,基金指数高频绝对收益不再具有明显周期性。FFF回归能较好地确定日内周期因子。     

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.     

基于系统动力学理论的军事物资保障系统分析与研究

从军事供应链理论的系统角度出发，对传统的保障模式进行优化整合，引进军事物资保障系统的概念。然后，以系统动力学理论为基础，分析了军事物资保障系统并运用Vensim_PLE软件进行计算机仿真建模。最后，通过对备选方案的评价分析，我们可以选出最优决策方案，并辅助决策者进行决策。     

引入供应链管理思想实现军事物流跨越式发展

供应链管理是物流管理的发展方向和趋势，是一体化的物流管理，是一种新的管理理念和模式。在军事物流领域借鉴和引入供应链管理思想，对提高军事物流保障能力和效益，促进军事物流跨越式发展提供了重要的契机和理论依据。本文从供应链管理的科学内涵、引入供应链管理的必要性以及应关注的几个问题等三个方面进行了论述。     

Do investors in Green Bond market pay a premium? Global evidence

We examine the pricing difference of Green Bonds (GB) and conventional bonds (CBs) in capital markets worldwide. Credit spread is used to observe whether investors would like to pay a premium for GBs over CBs. This study uses panel data regression with hybrid model to analyse daily observations over the period 2016 to 2017. We employ Option-Adjusted spread (OAS) to measure the credit spreads of bonds while controlling for bond specific, macroeconomic and global factors that influence the spread. With the hybrid model used in the panel data analysis, we were able to capture the fixed-effects of variables in a random effect model. We find that GBs are traded at a premium of 63 basis points (BPS), compared with a comparable corporate bond issue. We find that the green label provides issuers an incentive to raise funds through issuing GBs while providing investors an opportunity to diversify their investments returns. Our findings provide several implications to the major stakeholders driving the GB market to scale up the market to finance the required level of global green investment needs. We stress an urgent need to support the growth of the GB market to achieve sustainable development through mitigating climate change challenges.

考虑违约距离的上市公司危机预警模型研究

在上市公司财务危机预警中,违约距离起着重要的不可替代的作用,仅考虑财务指标并不足以完全解释企业财务危机发生的原因.文章应用Merton模型对2002～2004年ST公司和相应配对公司的危机发生之前的违约距离进行了研究,发现危机公司违约距离在危机发生前第三年明显低于正常公司的相应值,违约距离比传统财务指标能更早地预警到企业财务危机的发生.结合违约距离因素的危机预警模型能更明显地提高模型的危机判断正确率.     

宏观投资的影响因素与实证分析

在界定宏观投资的基础上，选择储蓄、价格、利润和利率等影响因素的代表变量，建立固定资产投资的理论模型；以1985－1999年为样本区间，采用SPSS统计分析软件包，对变量数据进行相关性分析和主成分分析，构建我国固定资产投资的回归模型；通过实证分析得出我国固定资产投资各影响因素的结论并给出相应的政策含义。     

黔西南“精神扶贫”工作开展的现状与不足

黔西南州是贵州省连片贫困的典型地区,是打赢脱贫攻坚战的关键区域。通过艰苦卓绝的奋斗,黔西南州的精准扶贫工作取得了重大成果。在“精神扶贫”领域,黔西南州在“扶智”“扶志”方面取得了很大成效,但还存在对“扶智”“扶志”认识不足、投入不足、主体错位,缺乏“扶智”“扶志”的文化自信等不足,这是持续打赢脱贫攻坚战面临的重大挑战。
