EVFTA是越南政府与欧盟委员会签署的自由贸易协定。本文的目的是通过国家之间的双边农产品贸易需求来检验越南与欧盟之间的自由贸易协定的效果,它涉及到从越南和欧盟的角度对农产品市场需求进行定量评估。CGE模型用于分析欧盟-越南自由贸易协定的潜在影响。该发现表明对越南一些主要农产品的预期影响。对现有数据的审查表明,与进口价值相比,关税的取消使越南的出口增长更快。自由贸易协定正在推动欧盟与越南之间的进出口结构发生渐进但积极的变化。它为通过增加金融直接投资进一步整合越南和欧盟贸易提供了一个很好的机会。这反过来又会扩大欧盟与越南之间的双边贸易。根据该条约,越南农民将获得更好的非歧视性市场准入,从而提高利润率。该协议将有助于帮助越南继续促进经济多元化、进出口、投资伙伴关系和市场多元化。在全球经济受到新冠病毒大流行的严重影响,加速经济关系、国际贸易和供应链调整的新趋势以及全球链价值的情况下,这些具有至关重要的意义。作为对越南主要合作伙伴承诺最高水平的协议,EVFTA将带来诸多好处,特别是促进对欧盟市场的贸易、吸引投资、创造经济发展引擎、创造就业机会……对开放市场的承诺将为企业创造许多增加出口营业额的机会,特别是在纺织品、鞋类、农业和水产养殖产品等潜在领域……越南对欧盟的出口营业额预计在2025年和2030年分别增长42.7%和44.37%比较没有一致意见。高标准实施EVFTA是长期推动国内经济改革、增长方式转变、出口结构转变,特别是提高商品技术含量的动力,朝着更具竞争力、创新和创新的经济方向发展。这可以看作是越南人表达对欧盟对越南出口的严格规定和标准的愿望和意见的机会。目前,欧盟也是越南最大的贸易伙伴之一,仅次于中国。这种合作使越南在进出口方面具有互补性,没有太多的直接竞争。为了了解EVFTA对越南的影响,农业作为审查部门,以了解这项自由贸易协定的影响。该研究旨在研究欧盟-越南自由贸易协定对越南农业贸易的潜在影响,作者认为,一旦越南与欧洲之间的自由贸易协定生效,这项研究是捕捉越南对欧洲国家农产品出口未来发展的努力之一。分析越南的竞争优势,以便当地出口公司了解他们如何与其他国家的农产品出口竞争。该研究还为越南政府的决策者提供了证据,他们了解他们在越南向欧洲国家出口路线图中的作用。该研究将定量和定性评估相结合,以减少采用定性或定量评估的弱点。在这种情况下,未来的研究人员将可以从阅读本研究中受益,因为他们可以利用研究结果在未来的研究中验证他们的一些论点。

Rice （Oryza sativa） is sensitive to salinity, but the salt tolerance level differs among cultivars,which might result from natural variations in the genes that are responsible for salt tolerance. High-affinitypotassium transporter （HKTs） has been proven to be involved in salt tolerance in plants. Therefore, wescreened for natural nucleotide polymorphism in the coding sequence of OsHKT1, which encodes the HKTprotein in eight Vietnamese rice cultivars differing in salt tolerance level. In total, seven nucleotidesubstitutions in coding sequence of OsHKT1 were found, including two non-synonymous and five synonymoussubstitutions. Further analysis revealed that these two non-synonymous nucleotide substitutions （G50Tand T1209A） caused changes in amino acids （Gly17Val and Asp403Glu） at signal peptide and the loop ofthe sixth transmembrane domain, respectively. To assess the potential effect of these substitutions on theprotein function, the 3D structure of HKT protein variants was modelled by using PHYRE2 webserver. Theresults showed that no difference was observed when compared those predicted 3D structure of HKTprotein variants with each other. In addition, the codon bias of synonymous substitutions cannot clearlyshow correlation with salt tolerance level. It might be interesting to further investigate the functional roles ofdetected non-synonymous substitutions as it might correlate to salt tolerance in rice.
