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

No amount of crystal ball gazing may help us fathom the full impact of the Covid-19 (C-19) crisis on business organizations in a distinct manner. Given the lack of precedence, any such analyses seem to demand routine revisions as we progress further up the “number of infected” curve. Most countries of the world have imposed restrictions on social congregations or even people working in close proximity to each other. Industries that produce and deliver information products and services therefore, have continued to function while those that manufacture physical products especially labor-intensive firms were forced to minimize operations or temporarily shut down. However, in most countries, physical products which were essential in nature were reluctantly permitted to be manufactured given the need for them in people’s everyday life. In this viewpoint, I draw upon three dimensions – information intensity of product/service, information intensity of process/value chain; along with a third dimension – essential nature of the product/service to help understand the immediate implications of C-19. I also present some anecdotal evidences of attempts to alter business models in these circumstances in order to address the challenges that certain product characteristics impose but at the same capitalize on the business opportunities presented by the essentiality of the products. 相似文献

建立双寡头Bertrand序贯博弈模型,比较均衡时四种环境规制手段的厂商RD激励大小。认为排污税和拍卖RD激励最高,在异质产品市场上,使用简单排放标准比排污权交易更能激励企业从事环境研发投资,获得动态效率提升。在环境治理方式选择上,切忌政策"一刀切",要充分考虑市场结构、规制目标和需求函数等诸多因素影响。 相似文献

产品设计本身就是文化的组成部分,因此设计必然反映和彰显文化。当设计创新与国家竞争力相联系的时候,涉及到文化层次是个必然的策略。通过分析传统符号在现代产品设计中的应用,我们应该认识到现代产品设计就不应只满足于套用传统符号来作为文化的装饰,而应该深入理解和应用传统文化元素,为产品设计增加附加价值。 相似文献
