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.     

Capturing the broader picture of value co-creation management

The interactional, interdependent, and dynamic nature of value co-creation has made value management in business relationships a particularly challenging issue for both academicians and practitioners. In addition, studies on this topic have mostly focused on managing value co-creation in isolation from the wider relational context without completely capturing the influence of other value processes on value co-creation. This paper examines the broader picture of value co-creation management by providing a model based on interlinked value processes, namely, value communication, value appropriation, value measurement, and value representation. We adopted a qualitative approach based on 86 interviews with managers of both customer and supplier companies, which operated in different industries. Results showed that the management of value co-creation implies considering complex patterns of interconnections with other value processes. In particular, the study will shed light on the centrality of value appropriation to co-create value and on the importance of value representation to coordinate ideas and enable future co-creation opportunities.     

Social work students' conception on roles within the family in Greece

The present article is based on a small-scale research that took place with third-year students in the department of social work at Technological Educational Institute of Patras. During class the students, who undertake the laboratory course ‘Social Work with Families’, were asked to discuss family roles and depict them on drawings. Analysing their drawings in a qualitative approach the findings suggest that students adopt traditional views on family issues and the family roles. Various gender stereotypes and prejudices were reflected in students' drawings and this is alarming for both social work education and practice.     

Associations between sleep consolidation in infancy and peer relationships in middle childhood

Sleep plays an important role in many aspects of children's development. Research on children's sleep and their peer relationships has begun to emerge in the last years. However, these studies are mostly cross‐sectional. The current study aimed to investigate the associations between infant sleep and peer relationships in middle childhood. The sample comprised 72 children. Sleep was measured at 1 year using a sleep diary completed by mothers. In the second and third grades of elementary school (7 and 8 years of age), mothers and fathers reported on their children's functioning with peers. When they were in third grade, children were interviewed regarding their friendship quality with a best friend. Results revealed negative associations between children's sleep consolidation (i.e., ratio of nighttime sleep) and parent‐reported peer problems, and positive associations between sleep consolidation and perceived friendship quality. These findings suggest that well‐regulated sleep in infancy may help children develop the skills necessary for later appropriate social functioning in peer contexts.

人民币汇率波动与贸易收支的协整分析

本文研究的是1985-2004年我国的进出口价格的需求弹性。首先给出了进出口价格需求弹性理论说明,接着通过平稳性检验、协整检验、建立误差修正模型等方法,分别对进口相对价格需求弹性和出口相对价格需求弹性进行实证检验。分析表明在我国ML条件成立,人民币汇率波动对我国进出口有显著的影响。     

法律关系客体之探究

受法律调整的社会关系即为法律关系 ,受刑法调整的社会关系即为刑事法律关系。刑事法律关系的客体应是刑事法律关系主体双方权利和义务所指向的、受刑法所保护的、被犯罪行为所破坏的社会关系 ,不应是具体的物、智力成果、行为。法理学、民法学、经济法学中均将法律关系客体界定为物、智力成果和行为 ,与刑事法律关系客体不一致。在理论上应将其统一起来
