Abstract: The signing of RCEP provides a huge opportunity to promote the high-quality development of China's economy. Trade liberalization measures, high-standard economic and trade rules, and regulation of new trade issues within the RCEP framework provide a solid foundation for forming the new development paradigm. However, RCEP's internal structural risks, external interference factors, and reform issues under the docking of standards also bring uncertainty to the dual-cycle development pattern. We should continue to deepen reform, strengthen technological innovation and economic cooperation, continue to expand the economic and trade space within the RCEP framework, actively eliminate internal and external structural risks of RCEP, and create a good environment for forming the new development paradigm.
