General Secretary Xi Jinping creatively puts forward the brand-new concept of "new quality productivity". In the current complicated international economic environment and grim global economic and trade situation, "accelerating the formation of new quality productivity and enhancing new development momentum" should be taken as the fundamental principle and action guide for China’s foreign trade. This article describes the new spatial pattern of China’s foreign trade, analyzes the new momentum of China’s foreign trade under the spatial reconstruction of global supply chain, defines and explains the "new quality productivity of foreign trade" that promotes the high-quality growth of foreign trade before proposing policy suggestions. This article holds that currently influenced by various factors such as trade protectionism, geopolitical conflicts, and manufacturing backflow, the global industrial and supply chains are accelerating its reconstruction, shifting their orientation from cost control, production efficiency, science and technology to supply security, industrial stability and geopolitical governance, demonstrating such features as regionalization, diversification, localization, digitalization, agglomeration and other forms that steadily point to a fragmented growth pattern. In this new spatial distribution pattern, China’s foreign trade is facing unprecedented risks and challenges. The export trade to developed economies in Europe and America has dropped sharply, and export enterprises are struggling for survival. Against this complicated and severe external environment, China, being the world’s largest manufacturing country, empowers the manufacturing industry with digital technology, vigorously promotes the transformation and upgrading of industrial structure, innovates product structure, and actively responds to the unfavorable situation of order transfer and export decline caused by "decoupling and chain breaking" and industrial chain relocation. The export of "new three products" represented by electric autos, lithium-ion batteries and solar cells has replaced that of labor-intensive "old three products", achieving the phased goal of stabilizing scale and optimizing structure, improving quality and efficiency, and injecting new momentum into the high-quality development of foreign trade. This article provides a detailed and in-depth analysis of the specific manifestations of new quality productivity in China’s foreign trade. It is maintained that data, information, and flow are key elements of new quality productivity in foreign trade. The integration of a new round of technological revolution and industrial transformation is the driving force behind new quality productivity in foreign trade. The integration of digital and physical economies, and that of virtual and real economies, provides a solid foundation for new quality productivity in foreign trade. New quality productivity in foreign trade has unique advantages and resilience driven by two wheels. Lighthouse factories are the backbone of new quality productivity in foreign trade, while unicorns are the driving force of new quality productivity in foreign trade. The new cross-border E-commerce models, overseas warehouses, full custody, and other new formats established on virtual aggregation platforms have formed new quality productivity in China’s foreign trade. It is necessary to support and enhance the new quality productivity of foreign trade with advanced manufacturing, emerging industries and future industries, and expand and boost the new quality productivity of foreign trade with a huge domestic consumer market.
