Group 1 - The article discusses the intensifying competition and cooperation among major global powers, highlighting the politicization and weaponization of economic issues, leading to a restructuring of the global value chain and international division of labor [1] - Since the reform and opening up, China has experienced two typical stages in the global value chain: initial entry into the global value chain and dual embedding within it [1][2] - The initial stage involved China leveraging its labor advantages to engage in low-value-added manufacturing, primarily through outsourcing from multinational corporations, which allowed for the development of export-oriented economic models [2][3] Group 2 - As China's demographic dividend diminishes and Western countries adopt a "de-globalization" stance, Chinese manufacturing faces pressures from both high-end production returning to developed countries and low-end production shifting to developing countries [4] - The key to overcoming low-end lock-in is to invest in advanced production factors, transforming the value chain into a learning and innovation chain, while also restructuring the global value chain to be more China-centric [4][5] - The dual embedding model allows Chinese enterprises to cluster in industrial parks, enhancing their ability to upgrade products and processes through shared resources and services [5] Group 3 - The restructuring of the global value chain post-US-China trade tensions is characterized by shorter, more regionalized supply chains and a steeper "smile curve," reflecting a shift in value chain division based on geopolitical considerations [6] - Developed countries are employing various measures to hinder China's industrial upgrades, including technology decoupling and investment restrictions, which aim to reshape the global value chain under their control [6][7] - In response, China needs to shift its strategy from merely integrating into the global value chain to constructing a national value chain, focusing on building an internal demand-driven global value chain [7] Group 4 - The internal demand-driven global value chain emphasizes self-sufficiency, dynamic competition, and the extension of industrial chains, as exemplified by China's high-speed rail sector leveraging domestic demand for innovation [7] - To achieve this, China must enhance its technological innovation capabilities, improve the business environment, and strategically guide the relocation of its manufacturing sectors [7]
