Mirroring in production? Early evidence from the scale-up of Battery Electric Vehicles (BEVs)
研究了汽车制造商在纯电动汽车生产中是否镜像了模块化设计，发现目前仍与传统燃油车混线生产，且关键系统自产而非外包，对模块化理论提出了挑战。
Abstract The mirroring hypothesis is central to modularity theory, positing isomorphism between technical interdependencies of a product and organizational arrangements. When a product’s design becomes more modular, a full mirroring response would change both its manufacturing and its supply chain. We evaluate this prediction for Battery Electric Vehicles (BEVs), observing whether automakers have mirrored the modular BEV architecture in either internal production processes, external sourcing arrangements, or both. Our data from 19 automakers show that, to date, BEVs are manufactured in their assembly plants alongside conventional internal combustion engine vehicles (ICEVs). New automakers with fully BEV plants utilize essentially the same production process. Furthermore, automakers make—or ally to make—key Electric Vehicle (EV) systems, rather than outsourcing them. We discuss the implications of this partial mirroring for modularity theory and ask whether these arrangements will persist once BEV sales surpass ICEVs.
