本文以中日石材贸易为研究对象，研究RCEP对其产生的贸易效应。本文首先介绍相关理论和RCEP相关规则，通过分析近年来中日本石材贸易的发展现状，测算中日石材贸易的RCA指数，得出中日石材产业的发展特点及地位。继而通过构建SMART模型，分别模拟短期和长期降税情景下，RCEP对中日石材贸易产生的贸易创造效应和贸易转移。得出结论：RCEP将给中日双方带来显著贸易创造和贸易转移效应，对中国来说总体上是负向的贸易效应，但中国可以制定相关策略扭转这种局面，最终实现中日共赢。

This paper takes the Sino-Japanese stone trade as the research object to study the trade effect of RCEP on it. The relevant theories and RCEP related rules are introduced first followed by the analysis of the development status of Sino-Japanese stone trade in recent years. The RCA index of Sino-Japanese stone trade is calculated for the development characteristics and status of the Sino-Japanese stone industry. Then, by constructing a SMART model, the trade creation effect and trade diversion effect of RCEP on Sino-Japanese stone trade under short-term and long-term tax reduction scenarios are simulated respectively. It is concluded that RCEP will bring significant trade creation and trade diversion effects to China and Japan, which is generally a negative trade effect for China. China, however, can formulate relevant strategies to reverse this situation and ultimately achieve a win-win situation between China and Japan.
