In this paper, the authors derive time-varying relative export competitiveness (REC) of the Cambodian rice sector from 1995 to 2018 and examine the key determinants of the REC.,Three different REC indexes are calculated in this paper. The authors also developed the relative symmetric export competitiveness (RSEC) index for calculation of comparative advantage. The short-run regression (SRR) model was applied for capturing the determinants of the REC.,The study results reveal that Cambodia's rice exports became relatively competitive over time. The key findings suggest the Cambodian REC was strengthened as a result of a successful implementation of rice policy and rectangular strategy. The benefits gained from EBA and BRI were found to be the factors contributed to the REC. The higher per capita income had a positive effect on the REC, while higher domestic prices reduced the REC in some phases of the sectoral development.,Further research is needed in two directions. First, the future studies might focus on other agro-products of Cambodia. Second, the development of the crop-specific factor endowment (CFE) model to consider the effect of endowment factors on the REC could be preferred in light of the data availability.,The research enriches the literature on the agricultural trade and provides a basis for further studies. This work makes a few contributions. First, it is the first study on the REC analysis for the Cambodian rice sector. Second, the latest 24-year data sets were covered. Third, a wide range of comparisons of REC among the world's top rice exporters was provided following implications of the various economic policies and foreign policy strategies, such as RS, EBA and BRI.

柬埔寨大米行业的相对出口竞争力

在本文中，作者推导出了 1995 年至 2018 年柬埔寨大米行业随时间变化的相对出口竞争力 (REC)，并检验了 REC 的关键决定因素。本文计算了三个不同的 REC 指数。作者还开发了用于计算比较优势的相对对称出口竞争力 (RSEC) 指数。应用短期回归 (SRR) 模型来捕捉 REC 的决定因素。研究结果表明，随着时间的推移，柬埔寨的大米出口变得相对具有竞争力。主要调查结果表明，由于稻米政策和矩形战略的成功实施，柬埔寨 REC 得到了加强。从 EBA 和 BRI 中获得的好处被发现是促成 REC 的因素。较高的人均收入对 REC 产生了积极影响，而较高的国内价格在部门发展的某些阶段降低了 REC。需要在两个方向上进行进一步研究。首先，未来的研究可能侧重于柬埔寨的其他农产品。其次，考虑到禀赋因素对 REC 影响的作物特定要素禀赋 (CFE) 模型的发展，鉴于数据的可获得性，可优先考虑。该研究丰富了农业贸易的文献，并提供了基础深度学习。这项工作做出了一些贡献。首先，这是对柬埔寨大米行业的 REC 分析的第一项研究。其次，涵盖了最新的 24 年数据集。第三，根据各种经济政策和外交政策战略（例如 RS、
