The growing share on the aerospace market is due to the increased supply of aircraft components, primarily engines (Figure 5).The changes in the global AM markets' "design" among other things have been caused by the implementation of industrial policies aimed at increasing competitiveness and accelerating growth through structural reforms. However, countries' priorities and implementation methods vary significantly. Industry 4.0 radically changes the understanding of industrial policy vector and stakeholders [Reischauer, 2018]. Germany, China, and the US are striving to maintain leadership by increasing value added in the manufacturing industry. France and Japan localize production, increase its sustainability, and reduce the negative effects of high labor costs. France aims to modernize its manufacturing basis and retain AM leadership, provided it can contain labor costs growth and related social factors [Blanchet et al., 2016]. Russia's industrial policy is mostly vertical in nature, providing selective support and "appointing champions" -industries Таble 1. Classification of AM markets Group Number of markets Composition Share in aggregate AM market (%) Industry 3.0 3 Electronics, optoelectronics, ICT 63.2 Industry 4.0 4 Additive manufacturing, biotechnology, life sciences, flexible production (including robotics) 27.2 Other* 4 New materials, aerospace, nuclear technologies, armaments 9.6* Products not directly related to Industry 3.0 and 4.0. COMTRADE data includes only public information on international trade in armaments. Thus the above estimates do not reflect this market's actual size. However, using this approach makes sense for two reasons. Other available data allows to estimate the overall arms market size without breaking it down into product types (e.g. the SIPRI Arms Transfers Database project). For us, it's important to consider structural shifts not only between markets but also within them, at the level of specific product groups. In line with the adopted approach, the arms market comprises not only armaments and their parts, but also prismatic infrared binoculars, optical telescopes, periscopes, navigation logbooks, and depth sounding equipment..
