We benefit from the results of the global supply chain every day. But do you know how the supply chain operates? The supply chain encompasses a series of activities, from sourcing raw materials to manufacturing products and finally, to sales and distribution. The goal is to deliver products to consumers with the lowest cost, highest quality, fastest speed, and maximum satisfaction. The supply chain is an incredibly complex system involving collaboration and competition among multiple countries, industries, and businesses. It has been continually evolving with history, transitioning from simple linear form to complex interconnected networks, which also reflects the progress of human society. This chapter, examining the development and characteristics of the supply chain from both temporal and spatial perspectives, analyzes its impact on the global economy and society. Additionally, we will look ahead to the future of the supply chain, delving into how it will cope with the digitization and the challenges among globalization. We will explore how it will leverage new technologies to enhance its adaptability and flexibility. Throughout this chapter, you will discover that the supply chain is not only a “chain” but also a dynamic “network.”
