In recent years, the issue of global climate change has become increasingly severe, prompting countries worldwide to intensify their control over carbon emissions to achieve sustainable development goals. As a crucial component of the modern economy, high-tech retail enterprises significantly influence the entire industry's sustainable development through technological innovations and business models. This study focuses on Chinese high-tech retail enterprises, employing a theoretical framework grounded in Resource Dependency Theory and the dialectics of productive forces and relations from a Marxist political economy perspective, supported by Structural Equation Modeling (PLS-SEM). The study identifies the degree of green technology application, corporate environmental policy response strategies, and consumer environmental awareness and demand as mediating variables. The aim is to deeply explore the impact mechanisms driving green and new-quality productivity in Chinese high-tech retail enterprises and to provide an in-depth understanding of the sustainable development of their green and new-quality productivity. The findings indicate that external resources such as policy support, technological innovation, and market demand significantly impact the green productivity of high-tech retail enterprises. Government environmental policies and subsidy measures provide institutional safeguards and resource support for enterprises; technological innovation drives the application and efficiency improvement of green technologies; and market demand for environmentally friendly products promotes the green transformation of enterprises. The study explores how enterprises can integrate different external resources to maximize the benefits of green productivity, including formulating policy response strategies, strengthening technological innovation and R&D investment, seizing market opportunities, and establishing cooperative relationships. These findings offer necessary theoretical support and practical insights into the resource dependency strategies and the mechanisms impacting the development of green productivity in high-tech retail enterprises. This study provides valuable theoretical and practical references for high-tech retail enterprises in promoting the development of green and new-quality productivity. It offers valuable suggestions and guidance for enterprise decision-making and policy formulation. By revealing the dialectical interaction between external resources and internal production relations, this study provides a systematic path analysis and strategic recommendations for achieving the Dual Carbon goals.
