Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management. This research focuses on the cross-border e-commerce context, to propose a blockchain-based framework, and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management. A general blockchain-based product traceability framework is introduced. This framework is based on a cross-border e-commerce supply chain context, incorporating a series of blockchain-based models, including multi-chain structure model, data management model and block structure model. Several core methods and algorithms are also developed, such as information anchoring method, key distribution method, information encryption algorithm and anti-counterfeiting method. The framework, models and methods form a complete and comprehensive solution, which are evaluated by applying to several typical problems and attack cases. The case analysis results show that the framework, models and methods can successfully deal with key recover problem, and protect against clone attack, counterfeit tag attack and counterfeit product attack. The effectiveness, extendibility, security, implementation and governance issues of applying these solutions are also discussed. This research contributes to the theoretical and practical literatures on blockchain technology, cross-border e-commerce and supply chain management research fields. 相似文献

粤港澳大湾区以其独特的地理优势,在国家发展大局中具有重要的战略地位。采用问卷调查、深度访谈和中介效应分析等方法,选取广东居民赴香港参加体育赛事者为调查对象,了解两岸居民参与体育赛事受到哪些因素的影响及其影响程度,帮助相关部门企业制定合理策略促进两岸体育爱好者交流及地方经济增长,同时进一步拓展了跨境消费行为研究,特别是跨境体育消费研究。结果显示,赛事产品因素及相关吸引因素对个人态度及行为意愿具有重要影响,而经济因素和交通因素对于跨境体育消费者的决策影响十分有限。通关因素、货币汇率因素对跨境参加体育赛事影响不明显。 相似文献

长期以来,滇越边民以地缘为条件,以族缘、亲缘为纽带的跨境流动非常频繁,并在中越两国关系发展的不同阶段发生变化。从"江外三猛屯方"的实证研究可以看出,双方哈尼族边民的跨境流动受中越两国关系影响甚大。市场经济时期,双方边民以族源、亲缘为重要纽带的跨境流动呈现出经济性流动占主导与经济利益优先的特征。 相似文献

跨国并购对我国的影响及相关对策研究 总被引：1，自引：0，他引：1
20世纪90年代以来,跨国公司为了迅速占领我国市场,实现其全球战略,不断加快在华的并购进程。同时,随着我国资本市场的日益完善、国有企业重组、产业结构调整和解决日益严重的就业问题等,我国也进一步加大了跨国并购的发展力度。换言之,我国正迎来一个跨国并购高速增长的时期,这对我国产业安全甚至经济安全产生了现实和潜在的影响。文章从跨国公司在华并购的现状出发,分析了跨国并购对我国产业安全带来的影响,进而从政府的角度提出了应对策略和建议。 相似文献

This paper presents the findings of a study undertaken by the United Kingdom Quality Assurance Agency for Higher Education (QAA), with support from the International Network for Quality Assurance Agencies in Higher Education (INQAAHE), aimed at investigating the challenges and limits to cross-border cooperation in the quality assurance of transnational education. The study builds on the outcomes of the recently concluded Erasmus Mundus project Quality Assurance of Cross-Border Higher Education (QACHE) and in particular the QACHE Toolkit developed as part of the project to foster cooperation between quality assurance agencies in quality assuring transnational education. Based on the responses to a survey sent to QAA’s partner agencies in key sending and receiving countries of transnational education, the study extract recommendations to agencies to help them developing viable strategies for inter-agency cooperation, identifying concrete ways in which they might or might not cooperate across borders. 相似文献

The aim of the study was to examine the role of migrants in cross-border learning in occupational contexts. The research data included 78 semi-structured and 20 life-course interviews with people who had migrated from Estonia to Finland or who were transmigrating between these countries. The interview data were analysed qualitatively through a combination of data-based and theory-guided content analysis. The results showed how the migrants had engaged in transnational brokering and boundary encounters between work communities across national borders. Transnational brokering had involved introducing new work techniques, clarifying organizational cultures, conveying best practices and explaining local work requirements and communication styles. These transnational brokers had supported the processes of perspective making and perspective taking by explaining local work practices and, more broadly, mind-sets to non-migrants both in the host society and in their country of origin. Theoretical concepts from situated learning theory and transnational migration studies were applied in the analysis. The study provides a new perspective through which to examine international and multicultural work environments and the transformation processes related to the increasing cross-border mobility of labour. 相似文献

An important aspect of the transnational lives of Polish migrants in the Netherlands is their frequent use of healthcare services in Poland. Transnational care use may be detrimental for the continuity and the quality of the care migrants receive. The current study aims to shed light on the antecedents of migrants' doctor visits in Poland. Drawing on a representative population-based sample of Polish migrants in the Netherlands (n = 1,082), logistic regression is used to assess whether length of stay in the Netherlands is negatively associated with the likelihood of doctor visits in Poland. The KHB decomposition method is used to determine the extent to which this potential association is mediated by three specific acculturation factors: ethnic identification, trust in the Dutch healthcare system and Dutch language proficiency. The models show that migrants who stayed in the Netherlands longer were less likely to visit doctors in Poland. Mediation analyses indicated that this effect was largely attributable to their greater Dutch language proficiency compared to their counterparts who arrived in the Netherlands more recently. Strong ethnic self-identification as Polish and lower trust in the Dutch healthcare system were also associated with a higher likelihood of visiting doctors in Poland. However, no significant mediation of the effect of length of stay via ethnic self-identification or Dutch language proficiency was found. The findings suggest that voluntary language programs may foster inclusion of Polish migrants in the Dutch healthcare system and reduce the need migrants perceive to seek care in their country of origin. 相似文献
