新冠疫情加速全球价值链重构：新冠肺炎疫情爆发以来，全球价值链贸 易被加速重构。其一，在新冠肺炎疫情爆发后，欧美发达经济体经济增 长明显放缓，而新兴市场国家受影响相对较小，成为了全球经济增长的 主要动力，承接了更多的全球需求；其二，疫情冲击下全球产业链分工 体系的脆弱性有所凸显，各国日益重视供应链产业链的安全，包括美日 在内的国家开始扶持产业链回归本土。在此背景下，东盟、拉美等地区 在全球价值链贸易中的地位明显提升。这一轮全球价值链的重构表现为 三种形式，一是本土化，部分延申在外的价值链环节回流国内；二是区 域化，区域价值链联系加强；三是多元化，广泛布局可替代的价值链。 三种形式的价值链重构都会带来全球范围内的产业转移，本土化要求制 造业回流，区域化和多元化也将带来全球生产的重新配置。

When a medical emergency arises, an air ambulance is a specially equipped helicopter or aircraft that is used to carry sick or injured patients over distances or terrain that would be too difficult for a traditional ground ambulance to travel.

The global aggregates market refers to the overall demand, supply, and trade of construction and industrial raw materials commonly known as aggregates. Aggregates, in this context, include sand, gravel, crushed stone, and other materials that are used in various construction and infrastructure projects. These materials are primarily used in the construction industry for applications such as concrete production, road construction, civil engineering, and building construction. Aggregates are also widely used in the manufacturing industry, especially in the production of glass and ceramics. The market encompasses both the production and consumption of aggregates on a global scale. The production side includes companies involved in mining, quarrying, and processing of aggregates, while the consumption side includes sectors such as residential and non-residential construction, infrastructure development, and industrial manufacturing.

Acrylonitrile is a colorless, volatile organic compound with a pungent smell. The highly flammable liquid is manufactured by the reaction of ammonia, propylene, and air in the presence of a catalyst, which contains a complex of catalytic oxides comprising bismuth, potassium, chromium, cobalt, cesium, cerium, nickel, iron, and molybdenum. The yellow color of acrylonitrile indicates the presence of impurities, and it needs to be purified before being used in chemical manufacturing.

The nuclear energy market includes the generation of electricity through the use of nuclear reactions. The market volume is calculated based on the amount of electricity produced by nuclear power plants, while the market value is determined by multiplying the amount of electricity produced with the wholesale price for electricity generation. All market data and forecasts are represented in nominal terms (i.e., without adjustment for inflation) and all currency conversions used in the creation of this report have been calculated using constant 2022 annual average exchange rates.

The drone market (known as unmanned aerial vehicle (UAV)) consists of the revenue from the sales of drones. The market is segmented into two major categories: commercial and consumer drones. However, military drones are not included in our market scope. Commercial drones are unmanned aerial vehicles primarily used for business purposes. These drones are versatile and can perform a diverse range of tasks, including but not limited to surveying land, inspecting infrastructure, delivering packages, and capturing aerial footage for movies and TV shows.

The global automotive manufacturing industry is dominated by large, multinational manufacturers including Toyota, Volkswagen, Hyundai, and General Motors. The leading players in this industry are tapping into the growing demand for hybrid & electric vehicles, while alliances within the industry are a common strategy. The automotive industry is continually facing new challenges, with globalization, individualization, digitalization, and increasing competition putting pressure on the industry. Moreover, companies are facing more stringent regulations in terms of their safety and environmental commitments. The competition in Electric Vehicles (EVs) and automated driving is growing more intense, yet it is conceivable that these technologies might be considered commonplace in 5 or 10 years. Beyond contending with their conventional rivals, these companies must also be adaptable to the emergence of startups and unconventional players in the automotive sector, including ride-sharing services.
