中国与日本、韩国的价值链互补性研究

通过测算GVC互补指数,研究中日、中韩的价值链互补性可以发现,中国和日韩大部分GVC的互补性较强,在价值链层面已形成梯度分工,与日韩的价值链分工逐渐向高端环节发展,并拥有主导区域和跨区域价值链的能力.在新冠疫情蔓延、全球价值链面临断裂风险的情况下,三国应进一步加强政治互信,实施协同创新驱动战略,积极推进中日韩自贸区建设,促进价值链深度融合与提升,并加强以区域内外产业园区为中心的价值链合作,优化营商环境,增强产业合作基础.     

产学研协同创新效率测度及影响因素实证分析——来自泛珠三角的区域层面数据

采用超效率DEA法测度泛珠九省在2007—2016年的产学研协同创新效率,并采用M almquist指数法考察效率的动态变动情况,最后采用Tobit模型验证协同创新效率的关键性影响因素.研究表明,泛珠九省的创新效率总体上趋于改善但也存在短期波动,其中贵州、海南两省的协同创新效率相对最低,而广东省的协同创新效率是泛珠三角区域中最高的.技术进步对协同创新效率的作用最明显,技术效率变动的贡献度却较小,这说明从管理和制度改善方面挖掘效益尚存在较大的空间.高校参与合作及转移知识的能力、企业吸收及应用知识的能力、政府及金融机构的支持程度、产学研合作关系对协同创新效率的改进都具有显著的正向影响,其中政府及金融机构支持的作用最为明显,而地区经济发展程度的影响则不显著.

What are the Determinants of Large‐scale Farming in China?

The Chinese Government has increased its focus on expanding farm scale to promote agricultural development since 2010. A series of favorable polices has been adopted to support large‐scale farming. Using a multivariate probit model and 2015 and 2016 rural household survey data, the present paper examines the factors that influence small farmers' decision to become large‐scale farmers. The empirical regression results suggest that the decision to become a large‐scale farmer is significantly influenced by household human capital, cooperative membership, marketing channels, land‐transfer contracts and government policies. However, the influence of these factors differs with respect to becoming large‐scale grain and non‐grain farmers. These results imply that policy tools should target these factors and the appropriate group of small‐scale farmers. Generally, both central and local governments should promote large‐scale farming by enhancing rural households' human capital, improving marketing channels and providing agricultural social services, as well as encouraging returning migrant workers to engage in large‐scale farming.     

Nature and determinants of household retirement savings behaviour in South Africa

This study investigates the savings behaviour among South African households using the General Household Survey data for the periods 2002–04 and 2008–10. The age-cohort analysis shows that households achieve their income peaks when the household heads are in their early forties, earlier than in most other countries. Although initial support for the life-cycle hypothesis framework in the form of smoothed consumption was found from multivariate analysis, a closer examination reveals that the consumption–income ratio is also smooth over the age and cohort variables. This indicates that savings rates do not follow a hump-shape pattern as required in the life-cycle hypothesis framework. While households are seen to be able to maintain their consumption in retirement years through government grants, a large portion of the grants seem to be utilised for savings. This shows that the government grants have the dual effect of sustaining consumption levels while disincentivising savings during working years.     

瑜伽馆顾客体验价值对营销策略的影响:以北京瑜伽馆市场调查为例

本文以瑜伽馆顾客体验价值为研究对象,旨在找出影响瑜伽馆顾客体验的因素,为促进瑜伽馆的发展提供参考。本文通过概览体验营销和顾客价值方面的研究文献,综合运用文献资料法、问卷调查法、访谈法进行研究,调查和分析了瑜伽馆顾客体验价值包含的因素,并根据这些因素的重要程度与瑜伽馆开展体验营销的关系进行了策略上的讨论。研究得出,影响瑜伽馆顾客体验价值的影响因素主要有产品、环境、价格、人员服务、关系、形象、传播七个方面。在这七个影响因素中,产品的两个细分因素教练专业能力和课程设置在影响顾客体验价值因素中重要程度非常高,是瑜伽馆开展体验营销的重点;环境、价格、人员服务的各个细分因素影响程度也很高,而关系、形象、传播的细分因素重要程度存在差异,影响程度较弱。     

家族企业主的政治联系、制度环境与慈善捐赠——基于全国私营企业调查的实证研究

家族企业的慈善捐赠是中国慈善事业的中坚力量,探究其影响因素对深化理解家族企业行为具有重要价值。文章基于2012年全国私营企业调查数据,采用Tobit回归模型,研究了家族企业主的政治联系、制度环境对慈善捐赠的影响。研究发现家族企业主的政治联系促进慈善捐赠行为,具有政治联系的家族企业主比没有政治联系的家族企业主更多地进行慈善捐赠,政治联系级别越高,慈善捐赠水平也越高。当企业所处地区的制度环境更完善时,政治联系对慈善捐赠的促进作用减弱。文章揭示了家族企业慈善捐赠行为的部分规律,对推动中国慈善事业的发展具有一定的政策含义。

Pricing the cloud: a QoS-based auction approach

ABSTRACT

Cloud computing is an evolutionary technology that offers on-demand resources and elastic services through the Internet. Most providers adopt fixed-price mechanisms (e.g. pay-as-you-go). However, a few providers have recently employed auction-like approaches to price cloud services. Meanwhile, cloud consumers pay more attention to Quality of Service (QoS) such as availability, which measures how well a service is performed. This paper proposes a novel auction approach that can efficiently allocate resources according to customers’ QoS preferences. The QoS-based pricing can generate more revenue than a fixed-price strategy. This research lies at the intersection of cloud computing, economics, and information systems.     

中国药品研发专利激励制度研究——基于《专利法》第四次修订

通过分析2020年专利法第四次修订内容,发现此次修订在专利制度上作出大幅度调整.其中有关药品专利激励制度新增了专利链接制度、药品专利期补偿制度,这对于激励新药研发具有重要的意义.但现有制度若想实现制度效率最大化,仍要解决配套制度问题,以及对于制度本身所涉概念内涵需要明晰.在制度效率理论指导下,从专利链接配套制度完善、专利信息登记平台搭建、三部门链接等角度为制度落实与效率提升问题提出对策建议.
