对外贸易结构技术扩散效应比较研究

借鉴新增长理论思想,构造一个用进出口内生技术进步增长模型,将进出口贸易对全要素生产率的促进作用分为进出口部门自身相对要素生产率的提高和对非进出口部门的技术外溢两类,考察比较货物贸易、服务贸易以及技术贸易对经济增长的影响。研究表明：货物贸易、服务贸易和技术贸易对非进出口部门均存在显著技术外溢;对外贸易技术扩散效应存在结构性差异,即技术贸易最大,服务贸易次之,货物贸易最小;货物贸易对自身要素生产率的提高并没有起到作用,而服务贸易和技术贸易均提升了自身部门的要素生产率,进而促进了经济增长。     

我国海岛经济价值分析及其开发保护策略——以舟山群岛为例

以舟山群岛为例,分析了海岛的经济价值是客观存在的,海岛经济价值随着效用的不断体现而得以增长。为充分利用海岛经济价值,应采取逐岛规划,分类开发;改善条件,加快开发;依靠科技,科学开发;着力修复,保护开发等对策,并需要国家给予相应的政策支持。     

消费者价格敏感度对大数据杀熟的抑制作用

近年来,电商平台利用大数据实施消费者杀熟成为社会广泛关注的议题。消费者价格敏感度对大数据杀熟现象具有抑制作用,情感态度在其中具有中介效用,但影响机制需要进一步研究。运用效果层次理论探究消费者价格敏感度对大数据杀熟现象的抑制作用,结果表明：产品差异通过影响消费者的情感态度间接影响消费者对电商平台大数据杀熟的抑制行为,网络口碑则直接影响消费者对电商平台大数据杀熟的抑制行为。消费者应将产品差异、网络口碑纳入个人消费参考标准,以此提高消费者价格敏感度,从消费端来抑制电商平台大数据杀熟行为。     

两种文学经典的夹缝中——中国现当代文学的文化语境

文学史的发展进程总是伴随着对某些文学经典的评价的变化,以及塑造出各个时代不同的文学经典的过程。对于中国现当代文学而言,一个非常突出的境况是,它有着两种不同类型的文学经典:一种源于时间差异的传统,另一种源于空间距离的异域,两种不同经典对于文学有着不同的诉求,而这种矛盾所形成的张力构成了中国文学在近代以来内部发展的动因。同时还应看到,两种文学经典在作为中国文学引导力量的另一面,则是两种经典本身也是被当下的文学创作和评价体制所规范。透过对于文学经典的分析,可以看到文学发展状况的一个侧面。     

普通高校学生健身运动处方及效果的分析

通过12周的教学实验对比,跟踪研究与分析,探讨了健身运动处方对大学生体育锻炼效果的影响。结果表明：实验前后男（女）1000m（800m）、肺活量、台阶指数指标均有显著性差异,说明在高校体育课程改革中,实施健身运动处方是可行的、有效的,能够满足大学生体育锻炼的个性化的需求。     

长三角一体化发展的边界效应研究——基于城际消费流视角

随着社会技术的进步与市场经济的深化，消费流在反映区域间经济活动的往来程度时显现出了优势。文章借助中国银联2018年城际消费流数据，基于调整后的Head-Mayer边界效应模型，对长三角城市群的市场一体化程度进行测算和评估。实证结果表明：长三角地区的统一市场尚未完全形成，城市边界和省际边界均对异地消费具有抑制作用；省际边界效应表现出异质性，其中上海与其他三省之间的边界对消费流的影响相对较弱，而浙江、江苏、安徽三省彼此之间的市场分割更为明显；长三角各城市的边界效应程度不尽相同，上海的城市边界效应强度为1.05，江苏省各城市的边界效应强度处于3.06~5.51之间，浙江省各城市的边界效应强度介于3.13~6.24之间，而安徽省各城市的边界效应程度最为强烈，在3.85~6.58之间分布。基于长三角区域经济一体化的发展现状，提出以下几点建议：首先，要肯定区域经济协调组织在推动区域经济发展过程中发挥的重要作用。其次，继续深化取消影响区域经济发展的人为阻碍的改革，进一步降低经济合作的障碍和成本。最后，需要积极借鉴国际区域合作经验来推动长三角地区发展。     

Kinship care or upbringing by relatives? The need for ‘new’ understandings in research

This article addresses knowledge production on formal kinship foster care. In spite of growing interest in this phenomenon, little attention has been paid to how kinship care should be understood in research – as a service under child protective services or as upbringing by relatives. Each of these understandings leads to different research questions and creates guidelines for what falls into or outwith the focus of research. In kinship care research, this phenomenon has primarily been studied as a service. Research that seeks to evaluate the effect of kinship care compared to non-kinship care is used as a case to discuss the implications for the type of knowledge that researchers produce. While we acknowledge the importance of this research, we demonstrate the many challenges it involves and why this should not be the primary focus in kinship care research. On the background of these limitations, we argue in favour of approaching kinship care as upbringing by relatives – as ways in which family life can be organised and structured. This can lead to relevant knowledge that will enable us to obtain a better understanding of what kinship care is and involves.     

Cross-border credit networks,banking risk contagion and suppression effects

From the perspective of risk contagion, it is difficult to balance the benefits and costs of banking globalization. We use data on cross-border syndicated loans intended to build heterogeneous credit networks among banking sectors in various countries to explore the introduction of banking risks into the network. Via social network analysis (SNA), we find that the global credit network has phased characteristics, and it is a source of exposure to global banking risks. However, the more important network position, that is, the greater centrality, identified shows that the banking industry is more stable. To explain these findings, we present and estimate the banking risk contagion model and the suppression effect model of contagion. Evidence suggests that the international credit network is the channel of risk contagion, and the long-term loan network and nonfinancial borrower network have a stronger contagion effect. Exogenous banking supervision and network endogenous closeness centrality can inhibit risk contagion. From a policy perspective, these findings indicate the need to supervise high-risk cross-border loans and maintain independence in the international credit network.Data Availability StatementThe data that support the findings of this study are available from the corresponding author, [Heng Zhao, email: zhao0501@mail.dlut.edu.cn], upon reasonable request.     

Short- and long-term effects of divorce and separation on housing tenure in England and Wales

This paper investigates the effects of marital and non-marital separation on individuals’ housing tenure in England and Wales. We apply competing risks event history models to data from the British Household Panel Survey and the UK Household Longitudinal Study to analyse the risk of a residential move to different tenure types, for single, married, cohabiting, and separated men and women. Separated individuals are more likely to move and experience a tenure change than those who are single or in a relationship. Among separated people, private renting is the most common outcome of a move; however, women are also likely to move to social renting, whereas men tend to move to homeownership. This pattern persists when we account for time since separation and order of move, indicating a potential long-term effect of separation on housing tenure. This long-term effect is especially pertinent to separated women who cannot afford homeownership.
