This Study Report is one of the outputs of APEC PPSTI funding project “Workshop on Catalyzing Quality STI Demand Raised by Demand-side of Technology Commercialization” (PPSTI 08 2021A). Experts from supply and demand sides of STI from member economies are invited to attend workshops organized by Project Overseer team. Most representatives introduced their practical cases, and some concrete ideas for cooperation in STI supply and demand relationships. The main task of this report is to build a more effective technology commercialization chain targeting at high-quality STI demands in order to promote a sustainable economic recovery in the APEC region, and to serve as a reference across the region for policymakers and the academia to formulate influential and efficient policies, which could promote scientific and technological achievement transformation ecosystem, further activate the supply-demand matching and diversified technology transaction mode, and strengthen the flexibility of the technology supply chain.
