Blockchain in Additive Manufacturing and its Impact on Supply Chains

Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results suggest opportunities that are related to intellectual property (IP) rights management, the monitoring of printed parts throughout their lifecycle, process improvements, and data security. The most important barriers for blockchain adoption in AM are an absence of blockchain‐skilled specialists on the labor market, missing governance mechanisms, and a lack of firm‐internal technical expertise. By addressing important limitations of AM, blockchain is expected to improve the competitiveness of AM in parts’ production, catalyzing the trend toward more decentralized manufacturing resulting in more agile, resilient, and flexible supply chains and reduced logistics costs. Beyond that, blockchain‐based AM platforms are expected to enhance supply chain visibility, drive supply chain digitalization, support supply chain finance, and contribute to the emergence of shared factory systems.     

实施知识产权战略——我国企业应对美国337条款的有效途径

我国加入世贸组织之后,中美之间的贸易战逐渐出现一些新的变化,在反倾销措施不断加强的同时,美国正在越来越多地使用对贸易和知识产权限制更为严格的337条款作为保护其贸易的手段,使中国企业蒙受了巨大的损失。因此,实施知识产权战略,是我国企业维护自身利益,跨越美国337条款这道贸易壁垒最有效的途径。     

基于 TCP/IP 的远程数字监控系统

根据美国国家经济研究局（NBER）的最新宣布,美国经济自2001年3月已经进入衰退。本文认为,美国此次衰退是难以避免的,这是经济周期的必然规律,由于此前虚拟经济与实体经济的发展脱离,形成泡沫,那些过剩的资本终究会退出,于是造成人们心理预期的过度反应,消费和投资需求出现大幅萎缩,而恐怖袭击事件则加速了衰退的进程。对中国而言,美国衰退的影响是利弊兼有,主要表现在出口、引资、经济格局等方面。

Critical resource: An institutional economics of the Internet addressing-routing space

This paper links the analysis of IP address policy to the established vocabulary and concepts of institutional economics. Internet addressing and routing are usually discussed in technical terms, yet embedded in this highly technical discourse are a number of critical economic concepts, such as scarcity, externalities, common pool resources, tragedy of the commons, and conflict over the distribution of costs. To solve these problems, governance institutions native to the Internet have evolved. Yet despite the centrality of addressing and routing to Internet governance, there is very little research literature that bridges economic, institutional and technical discussions of IP addressing and routing. This paper connects the techno-economic discussion to analysis of institutions and governance arrangements.
