Constructing a Sustainability Evaluation Framework for China's Alloy Assembly Models （AAM） : An Empirical Analysis of the Pearl River Delta Region = 중국 합금 조립 모델（AAM）에 관한 지속가능성 평가 프레임워크 구축: 주강 삼각주 지역 실증 분석

다국어 초록 (Multilingual Abstract)

Against China's ＂dual-carbon＂ strategy and rising green trade barriers, the Alloy Assembly Model （AAM） industry faces the challenge of transforming from traditional manufacturing to green sustainable development. However, tailored evaluation systems for this niche industry are scarce, and general standards fail to capture AAM's unique combination of precision manufacturing and IP cultural attributes. Thus, a scientific, industry-specific evaluation system is urgently needed.
This study bridges the gap by constructing a ＂dual-layer architecture＂ for sustainability evaluation. The core layer covers environment, economy, and society; the extension layer incorporates brand IP cultural attributes, expanding evaluation scope from physical to cultural value.
Methodologically, the Pearl River Delta, China’s most concentrated AAM region, serves as an empirical analysis object. The Delphi method screened indicators; EFA validated structural validity; AHP quantified weights; and robustness tests confirmed model applicability across enterprises.
Results show reliable practical effectiveness: horizontally, the framework differentiates sustainability performance among AAM brands of varying scales; vertically, tracking a single brand from T0 to T2 confirms high sensitivity for monitoring improvement effects.Overall, this study advances the theoretical evaluation system for AAM brand sustainability and offers a replicable methodology for similar cultural and creative brands, providing theoretical and practical value for green transformation and cultural capacity enhancement of regional manufacturing industries.
