Abstract: E-commerce supply chains are potentially at risk from cyber-attacks. Consumers who purchase goods online also risk having their private information being stolen. Thus, businesses are investing to improve cyber-security at a non-trivial cost. In this talk, we discuss an analytical study on e-commerce supply chains with considerations of cyber-security. To be specific, in the basic model, we first derive the equilibrium pricing and cyber-security level decisions in the supply chain. Based on real-world practices, we then explore whether or not governments should impose cyber-security penalty schemes. Our findings show that when the government is characterized by having sufficiently high emphasis on consumer surplus, implementing the penalty scheme is beneficial to social welfare. Moreover, once it is beneficial to implement the penalty scheme, the government should charge a very heavy fine. This may explain why in the real-world, governments basically always adopt a polarized strategy, i.e., either do not impose penalty or impose a super heavy penalty, on cyber-security problems. Then, we examine how adopting blockchain technologies will affect the government's choice of imposing penalty. We uncover that when it is beneficial to have government's penalty scheme, the technology benefit-to-cost ratio is a critical factor which governs whether the optimal penalty will be lower or higher with the adoption of blockchain technologies.

Abstract: Today, the research and development of sustainability and space technology such as the use of satellite to monitor global climate change, forest fires, remote sensing and melting glaciers etc. enable the safety and health of our planet as well as the space environment. The issue of space resources and space economy has gained many research attention and interests, and many countries have launched their space missions to explore the deep space to meet the current needs of society and future benefits of mankind. In this talk, the speaker will discuss some of the key technologies, opportunities and challenges of sustainability and space resources. In particular, it will introduce some of the research works and developments contribute by the Hong Kong Polytechnic University's research team in space missions. One of the future sustainability technologies in the utilization of space resources using Space Solar Power Station will be reviewed, and with the advancement and innovation will provide mankind with an inexhaustible source of efficient and clean energy.
