The concepts of trade competitiveness and complementarity function as key indicators for assessing the strengths and weaknesses of a nation's export profile, as well as predicting future trade trajectories. Analyzing the levels of competitiveness and complementarity within the agricultural sectors of Cambodia and China is imperative for understanding and comparing their respective competitive advantages. This study utilizes quantitative research methodologies to analyze the agricultural trade dynamics between China and Cambodia before and after the pandemic. Specifically, the research involves the calculation of the revealed comparative advantage (RCA) index, the trade complementarity index (TCI), the trade intensity index (TII), and the Grubel-Lloyd (GL) index, covering the period from 2017 to 2022. The data is from the UN Commodity Trade Statistics Database through the HS code 1-24. The study used a three-year period as a short research phase and applied two phases to compare pre-pandemic and post-pandemic. The empirical results demonstrated that China and Cambodia both exhibit a strong comparative advantage in exporting specific items. From 2017 to 2019, China has comparative advantages in exporting HS items 05,13 and 16, and Cambodia has comparative advantages in exporting HS items 10,11 and 17. From 2020 to 2022, China has a comparative advantage in exporting HS item 13, and Cambodia has a comparative advantage in exporting HS item 10. Both China and Cambodia have specific complementary agricultural items in bilateral agricultural exports from 2017 to 2019, but China does not have complementary exports in its exports and Cambodia's imports from 2020 to 2022. The trade intensity index underscores the advantages of their bilateral trade in the direction of China's exports to Cambodia. Inter-industry advantages are identified in specific agricultural products. This study is beneficial for the Cambodian government and relevant stakeholders in formulating sustainable policies to promote agricultural trade after pandemic. The insights derived from these indices will furnish a rigorous foundation upon which the Cambodian government can develop and implement evidence-based sustainable strategies to optimize and enhance its agricultural trade performance.
贸易竞争力和互补性概念是评估一个国家出口概况的优势与劣势以及预测未来贸易轨迹的关键指标。分析柬埔寨和中国农业部门的竞争力和互补性水平对于理解和比较它们各自的竞争优势至关重要。本研究采用定量研究方法来分析疫情前后中国和柬埔寨之间的农业贸易动态。具体而言,该研究涉及计算显示性比较优势(RCA)指数、贸易互补性指数(TCI)、贸易强度指数(TII)和格鲁贝尔 - 劳埃德(GL)指数,涵盖2017年至2022年期间。数据来自联合国商品贸易统计数据库,通过HS编码1 - 24获取。该研究将三年期作为一个短期研究阶段,并应用两个阶段来比较疫情前和疫情后情况。实证结果表明,中国和柬埔寨在出口特定商品方面都表现出较强的比较优势。2017年至2019年,中国在出口HS编码05、13和16商品方面具有比较优势,柬埔寨在出口HS编码10、11和17商品方面具有比较优势。2020年至2022年,中国在出口HS编码13商品方面具有比较优势,柬埔寨在出口HS编码10商品方面具有比较优势。2017年至2019年,中国和柬埔寨在双边农产品出口中都有特定的互补农产品,但2020年至2022年中国在其出口与柬埔寨进口方面不存在互补出口情况。贸易强度指数突出了中国对柬埔寨出口方向上双边贸易的优势。在特定农产品中发现了产业间优势。本研究有助于柬埔寨政府和相关利益攸关方制定疫情后促进农业贸易的可持续政策。从这些指数中得出的见解将为柬埔寨政府制定和实施基于证据的可持续战略以优化和提升其农业贸易表现提供坚实基础。
