Core Viewpoint - The effective supply of international public goods is crucial for global governance, with the Shanghai Cooperation Organization (SCO) demonstration zone serving as a new platform for international cooperation under the Belt and Road Initiative, enhancing its role as a platform builder, resource linker, and solution provider [1][2]. Group 1: Platform Builder - The SCO demonstration zone can further expand its supply space by deepening its existing public service platforms, such as the SCO Economic and Trade Comprehensive Service Platform and the Qingdao SCO Pearl International Expo Center, to continuously provide international public goods elements like industry, scenarios, ecology, and lifestyle to SCO and Belt and Road countries [1]. - There is potential to broaden the scope of cooperation, particularly in the international energy sector, by expanding into energy trading, supply chain finance, and digital services [1]. Group 2: Resource Linker - The SCO demonstration zone has initially established a linkage open pattern, serving as a hub supported by other domestic and international open platforms, and aims to attract more high-quality domestic and international resources to enrich the supply of international public goods [2]. - In trade services, the focus is on accurately linking domestic and international business entities and trade resources to accelerate the creation of a "data mother port" and "practical blueprint" for the economic and trade development of SCO member states [2]. Group 3: Solution Provider - The SCO demonstration zone should provide systematic solutions to SCO countries, leveraging the multilateral cooperation platform of the SCO's industrial and supply chains, and deepen bilateral cooperation mechanisms through the "friendly city cooperation" dialogue [2]. - There is a need to explore the establishment of a regional economic and trade cooperation "big customs clearance" mechanism, enhancing mutual recognition in inspection, quarantine, certification, and recognition, as well as strengthening information exchange and regulatory cooperation [2]. - The development of international public goods is complex and challenging, necessitating effective communication mechanisms and supportive policies to enhance the quality and efficiency of international public goods supply [2].
