Report Industry Investment Rating The provided content does not mention the report industry investment rating. Core Viewpoints of the Report - The escalation of the tariff event has accelerated the process of self - controllability in key areas. China is using "independent innovation" to drive "import substitution" and upgrading the high - end manufacturing supply chain [2]. - The semiconductor, computer, AI, and military industries are expected to benefit from the trend of self - controllability. The semiconductor industry is in an upward cycle, the computer industry is gradually recovering, the AI industry has more development opportunities, and the military industry shows strong resilience [7]. - Some convertible bonds, such as Xingfa Convertible Bond, Weil Convertible Bond, Daotong Convertible Bond, and Kelan Convertible Bond, are worthy of key attention [9]. Summary According to the Directory 1. Breakthrough and Establishment: Accelerated Implementation of Self - Controllability in Key Areas 1.1 Tariff Event Review - In early April 2025, the Sino - US tariff event escalated. The US continuously increased tariffs on Chinese goods, and China took counter - measures. The event objectively accelerated the process of domestic substitution [15]. 1.2 Semiconductor Industry - The self - autonomy process of the Chinese semiconductor industry has accelerated. China is considering strengthening cooperation with other regions to diversify the supply chain, but the key lies in independent innovation. The "integrated circuit origin rule" promotes the transfer of the industrial chain to the domestic market [19][20]. - In terms of semiconductor materials, China is trying to break through the import dependence on key materials such as CMP polishing materials, high - end photoresists, and electronic special gases. Some domestic companies have achieved certain results [21]. - For semiconductor chips, the tariff event has a short - term impact on imports, but it also accelerates domestic substitution. In the long run, it promotes the construction of a "de - Americanized" supply chain [24][25]. 1.3 Information Technology Application Innovation (ITAI) - The tariff event has a short - term impact on the ITAI industry but catalyzes long - term domestic substitution. The ITAI industry is upgrading from "usable" to "good - to - use" [26]. - Huawei's HarmonyOS has achieved breakthroughs in technology and ecological construction. It faces challenges in application and developer ecosystems but has the potential to form a tripartite situation with Android and iOS [28][30]. - The tariff event accelerates the R & D and iteration of domestic industrial software, promoting its market penetration and competitiveness [32][35]. 1.4 Satellite Internet - The satellite Internet industry in China has transformed from policy - driven to technology and market - driven, with a complete industrial chain. It has achieved technological breakthroughs but also faces challenges such as security protection and standardization [36][39]. 1.5 Domestic Computing Power - The domestic computing power industry is in a critical turning point from following to leading in technology. It has achieved multi - dimensional breakthroughs in basic software and hardware, and the market is in a virtuous cycle of investment and application [42][43]. 1.6 National Defense and Military Industry - The national defense and military industry has a high degree of self - controllability in the supply chain, showing strong resilience in the tariff event. The military electronics and aerospace industries have achieved system - level development [45][46]. 2. The US Imposes Tariffs on China, and the Self - Controllable Sector May Become the Dominant Force 2.1 Semiconductor Industry - The global semiconductor industry is recovering, entering an upward cycle. AI development and automotive intelligence drive the industry. Some leading companies have achieved significant performance growth. Key convertible bonds to focus on are Weil Convertible Bond and Xingfa Convertible Bond [47]. 2.2 Military Industry - In 2024, the performance of military industry listed companies showed a more significant structural differentiation. Leading enterprises maintained growth, while small and medium - sized manufacturers faced challenges [50]. 2.3 Computer Industry - In 2024, the computer industry gradually recovered. Leading enterprises achieved performance growth through innovation and market expansion. Daotong Convertible Bond is worthy of attention [56]. 2.4 AI Industry - In 2024, the AI industry had more development opportunities. Leading enterprises achieved performance growth through innovation. The industry is expected to benefit from the expansion of application scenarios and policy support. Kelan Convertible Bond is worthy of attention [58]. 3. There Are Many Relevant Convertible Bonds, and Some Can Be Focused on 3.1 Xingfa Convertible Bond - Xingfa Group has transformed from a traditional chemical enterprise to a high - end chemical new material supplier. Its business is distributed at home and abroad, and its net profit has increased significantly [61]. 3.2 Weil Convertible Bond - Weil Semiconductor is a leading global semiconductor design enterprise. Its performance has grown significantly, and it is in a leading position in the industry [63][65]. 3.3 Daotong Convertible Bond - Daotong Technology is a leading global enterprise in automotive intelligent diagnosis. Its net profit has increased steadily, and its overseas business revenue accounts for a high proportion [67]. 3.4 Kelan Convertible Bond - Kelan Software is an important participant in the financial technology field. Its performance has grown steadily, and it continues to expand its business areas [70].
