Research on the Impact of RCEP on Chemical Products Trade between China and Japan

RCEP (区域全面经济伙伴关系协定)是由东盟十国发起，中国、日本、韩国、澳大利亚、新西兰五个国家受邀签订的多边协定，对中日化工产品贸易的结构调整与发展方向具有深远影响。本文通过分析中日化工产品贸易的现状，发现两国贸易呈现显著互补性：中国以出口基础化工原料为主，日本则以高端化学品为核心。RCEP框架下，因部分高附加值产品关税减免有限、技术标准差异及中日产业同质化竞争加剧而面临贸易转移效应，此外，贸易失衡等因素会进一步制约贸易深化。研究提出优化供应链效率、加速产业数字化转型与供给侧改革等建议，为深化中日化工贸易合作、优化区域产业链分工提供了理论参考与实践路径。RCEP (Regional Comprehensive Economic Partnership Agreement) is a multilateral agreement initiated by ten ASEAN countries and signed by China, Japan, South Korea, Australia and New Zealand at the invitation of five countries. It has a far-reaching impact on the structural adjustment and development direction of China-Japan chemical products trade. Based on the analysis of the current trade situation of chemical products between China and Japan, this paper finds that the trade between the two countries shows significant complementarity: China mainly exports basic chemical raw materials, while Japan mainly exports high-end chemicals. Under the framework of RCEP, due to limited tariff reduction and exemption of some high value-added products, differences in technical standards and intensified competition between China and Japan in the homogenization of industries, it will face trade diversion effect. This study puts forward suggestions on optimizing supply chain efficiency, accelerating industrial digital transformation and supply-side reform, which provides theoretical reference and practical path for deepening China-Japan chemical trade cooperation and optimizing regional industrial chain division of labor.
