Investment Rating - The report does not explicitly provide an investment rating for the aerospace industry. Core Insights - The commercial aerospace sector is rapidly developing, driving innovation across high-end manufacturing, information communication, new materials, and new energy sectors, while integrating into various economic and social fields [3][10]. - The establishment of a comprehensive aerospace economic measurement system is deemed feasible, important, and urgent, reflecting the contributions of aerospace to the economy and measuring the scale of the commercial aerospace industry [6][9]. Summary by Sections Section 1: Importance of Aerospace Economic Measurement - The concept of "aerospace economy" describes the economic implications of aerospace technologies and products, with the commercial aerospace industry scale estimated based on the aerospace economic scale, which in the U.S. accounts for approximately 80% [10]. - The aerospace industry has evolved through three stages: military and research aerospace, civilian aerospace, and the rapid development of commercial aerospace, with significant applications in environmental monitoring, urban planning, and disaster prevention [11]. Section 2: Measurement as a Response to Trends - The measurement of aerospace economics is a necessary choice to align with the development trends and statistical needs of the aerospace sector, especially as the demand for accurate statistics has increased due to the rapid growth of the commercial aerospace industry [15][18]. - The government has recognized commercial aerospace as a new growth engine, emphasizing the need for data-driven decision-making in aerospace governance [17]. Section 3: Current Measurement Challenges - There are significant discrepancies in the measurement of aerospace economics in China, including unclear definitions, diverse statistical standards, and inconsistent reporting, which hinder effective domestic and international comparisons [20][21]. - The report highlights the need for a unified measurement framework to support accurate analysis and decision-making in the aerospace sector [22][26]. Section 4: Proposed Measurement Framework - The report suggests the establishment of a "China Aerospace Economy and Core Industry Directory" to categorize and identify relevant industries based on international standards [49][51]. - The proposed framework includes the design of a satellite account for aerospace economics, which would encompass supply and use tables, balance sheets, and input-output tables to meet the statistical needs of various stakeholders [55][60].
