人民币汇率失衡及贸易壁垒对我国出口行业影响异质性研究

贸易摩擦、新冠疫情使我国经济贸易面临严峻挑战,人民币汇率波动及贸易壁垒将常态化地影响我国出口贸易.在加快形成以国内大循环为主体、国内国际双循环相互促进的新发展格局背景下,文章基于HS分类原则,选取WTO等机构的贸易数据,通过构建BEER模型测算了人民币汇率失衡程度;通过建立固定效应面板模型研究了人民币汇率失衡及贸易壁垒双因素对我国出口行业影响的异质性.研究表明:人民币汇率失衡对我国出口贸易整体上具有显著负向影响,非关税壁垒对我国出口贸易整体上具有显著正向影响;关税和非关税构成的贸易壁垒与人民币汇率失衡双因素对我国出口贸易具有显著抑制作用,并对不同出口行业的影响存在异质性;人民币汇率失衡与非关税壁垒双因素对大多行业均具有显著负向影响,人民币汇率失衡与关税壁垒双因素对不同行业影响的正负效应及程度大小有异质性.因此,建议通过运行逆周期因子等完善人民币汇率自我修正机制;通过引导出口企业了解使用外汇衍生品等促进外汇衍生品市场运行机制的健全;通过加强"海外仓"建设及深耕RCEP框架下的东盟十国市场等实施出口行业差异化贸易策略;通过提升自主科技创新能力等加快出口行业产业转型升级,推动双循环,实现我国出口贸易高质量发展.     

“They give you back that dignity”: understanding the intangible resources that make a transitional house a home for homeless families

Approximately 33% of the homeless population in 2017 were families with children. Researchers have argued for interventions and services to employ an ecological perspective to mitigate some of the unintentional harm inherent in existing programs designed to serve homeless families. This paper utilized a case study of a transitional housing program to (1) determine how well the program met recommendations informed by the ecological perspective and (2) explore underlying themes across recommendations. Past and current residents of a transitional housing program participated in semi-structured interviews as part of a program evaluation. Interviews were deductively and inductively coded to meet aims 1 and 2, respectively. Residents identified several aspects of the program that met the ecological perspective recommendations including culturally-responsive services, trauma-based services, and social and community connections. Major underlying themes spanning across recommendations included interpersonal resources (caring, sense of belonging), empowerment resources (advocacy, family preservation), impact on family (family life, positive youth development), and communication. This case study, through the analysis of residents’ perspectives, highlights the important role of transitional housing programs in providing a supportive, empathetic, empowering, and home-like environment that gives residents “back that dignity” so they are emotionally and physically prepared to successfully transition to permanent housing.     

城镇职工基本养老保险税预测研究——以浙江省为例

在当前经济形势下，逐步开征基本养老保险税是实现缓解各省养老保险基金缺口、减轻企业负担以及推进养老保险全国统筹三者协调发展的重要决策。本文以浙江省为例，基于2005-2016年的历史数据，对有关参数进行线性拟合分析并加以合理设定，对税率和养老金替代率分别按高中低和高低进行假设，形成六种方案进行测算。研究发现当养老金替代率为35%，税率为14%（方案五）时，基础养老金收支平衡比较稳定；进一步研究发现浙江省未来30年内养老保险社会统筹基金的平均税率为1256%，同时基本养老保险税率降低可为正在试点中的长期护理保险制度留出发展空间。进而本文对我国养老保险税制提出相应的配套政策建议。     

基于供求关系的房价波动分析

基于1999—2017年中国35个大中城市的面板数据，构建基于供求关系的面板回归模型，从国家和区域两个层面对造成房价波动的原因进行探究。结果表明:价格预期在全国和区域模型中均对房价有显著的正向影响，且在大多数地区，其影响力大于其他因素；人口对房价有正向影响，但只在北部沿海、东部沿海和南部沿海显著；收入对南部沿海、黄河中游和西南地区的房价均有显著的正向影响，而在北部沿海、东部沿海、长江中游、西北地区和东北地区，该因素对房价的影响并不显著；除全国和西南、西北地区外，房屋造价作为成本因素对绝大多数地区的房价有正向影响；信贷的可获得性作为政策因素对房价有正向影响，除南部沿海和黄河中游外，在其他区域均显著；住宅开发投资与住宅价格呈负相关关系，但其只在少数经济发达地区显著。因此，未来对房地产市场的调控应根据区域房价波动影响因素的不同区别对待，因地制宜。     

地方党政主要领导职位空缺的现状、成因及对策

地方党政主要领导职位空缺是指在领导干部选任和调配过程中，由于诸多常规或非常规原因导致某一地区的党委或政府部门主要领导职位在较长时间内空缺，进而直接或间接影响地方党政工作的特殊现状，广泛存在于各级、各地党政部门。由于我国有关干部职位空缺的制度建设和管理规范尚不完善，地方党政主要领导职位空缺产生一些消极影响，主要表现为不利于地方党政机关运行，存在腐败风险，触发舆论风险等。在充分认识空缺危害性的基础上，深入分析造成职位空缺的干部调配因素、选任导向变革因素以及其他非常规因素等，从完善遴选机制、衔接制度、保障机制、舆论生态治理、干部教育等五个方面切实解决地方党政主要领导职位空缺带来的一系列问题。     

企业利用FTA出口的影响因素分析

当前,以FTA为代表的区域贸易协定正逐渐成为各国开展经济战略合作与竞争的重要手段,但是现实中我国企业对FTA的利用率并不高。为了探寻其中的原因,首先从FTA使用成本和收益的角度建立了一个分析影响企业FTA利用率的理论模型,探讨了企业FTA策略选择背后的作用机制。其次,基于2017年中国—东盟FTA的问卷调查数据,利用有序probit模型进行了实证研究,发现企业获取FTA信息的难易程度、申请原产地证书的时间等FTA使用成本是影响中国企业FTA利用率的重要因素;利用FTA出口则有助于企业增加出口量,使其出口产品更具价格优势,并有助于企业加入全球/区域生产网络和产品供应链。最后,异质性检验结果表明,相对于生产型企业,获取FTA信息困难程度的降低、企业申请原产地证书时间的缩短等更有利于提高外贸型企业的FTA利用率;大规模企业对FTA的利用率受FTA使用所得收益的影响较大,而小规模企业对FTA的利用率则对FTA使用成本更为敏感。为了提高企业对FTA的利用率,政府应当扩大对FTA相关政策的宣传,提高企业的认知水平,同时简化各种审批手续,努力缩短原产地证书申请所需时间。     

Experiences of homelessness by people seeking asylum in Australia: A review of published and “grey” literature

This review examines the current published and “grey” literature relating to the experiences of homelessness by people seeking asylum within Australia. While many people seeking asylum have experienced homelessness during their flight, inadequate and unaffordable housing are a feature of the settlement experience for a large number of new arrivals to Australia, putting at risk their successful settlement. This study aims to explore the factors influencing access to stable housing. A systematic review of the academic literature and a search of the grey literature identified 11 articles and 20 documents related to homelessness and people seeking asylum in Australia. The academic literature included a variety of methods and approaches to the investigation of the experience of homelessness in Australia. The grey literature was more practice based, including evaluation and research reports, submissions, and newsletters. Findings suggest that experiences of homelessness are multifaceted and have a range of influences, including policy, financial stress, lack of access to education and employment, and a lack of affordable and suitable housing. Any solutions to address homelessness need to be similarly diverse. Discrimination from real estate agents and employers was also identified as a barrier to housing for many people seeking asylum, an issue that will need to be addressed at a systematic level. The lack of research published in the academic literature means that although there may be some programmes or solutions operating in the community, as demonstrated in the grey literature, this information is not being shared beyond organisation websites or subscriber lists, resulting in a lack of coherency or sharing of solutions. This review highlights the need for further attention to the factors influencing homelessness in asylum seekers, the experience of homelessness, and how these can be addressed by government and non-government led strategies and policy development.     

汇率货币模型的非线性协整关系检验——基于深度GRU神经网络

本文采用深度门控循环单元（GRU）神经网络探讨三种汇率货币模型（弹性价格、前瞻性和实际利率差模型）的非线性协整关系。GRU技术在深度学习中具有智能记忆、自主学习和强逼近能力等优点。为此，本文运用该技术对6组典型浮动汇率制国别数据进行了非线性Johansen协整检验。结果表明，汇率与宏观经济基本面之间存在非线性协整关系，从而说明了货币模型在非线性条件下的有效性，以及先进的深度学习工具在检验经济理论中的优势。     

中国基本医疗保险的实际参保率及其分布特征:基于多源数据的分析

全民覆盖是基本医疗保险降低国民医疗费用负担的前提条件。中国基本医疗保险是否实现了全民覆盖仍存在争议。本文利用多源调查数据,分析了我国基本医疗保险实际参保率及其分布特征。不同来源的数据基本证实,2015-2016年,中国仍有超过10%的国民没有参加任何一项基本医疗保险制度。其中,城镇居民、非农户口和没有户口的居民、东北地区、年轻人、儿童、未就业人群、低收入人群、在校学生以及流动人口基本医疗保险实际参保率更低。城乡居民实行自愿参保,因管理部门分割、信息系统不统一导致的重复参保以及因财政补贴制度导致的户籍地参保等制度设计,是导致基本医疗保险未能实现全民覆盖的根源。要实现基本医疗保险全民覆盖,解决国民医疗后顾之忧,未来我国基本医疗保险应实行强制参保、以家庭为单元参保、常住地参保,建立全国统一的基本医疗保险信息系统,并鼓励发展补充性医疗保障制度。
