This paper aims to focus on testing the long-run relationship between fish production and two main variables, the foreign direct investment inflow and the marine trade balance in Oman, which is one of the Arab Gulf countries, during the period 1985-2016.,This study uses what known as the two-step Engle–Granger cointegration test to give evidence for the long-run relationship among the variables.,The results show that there are a negative long- and short-run relations between fish production and marine trade balance; moreover, any shocks will be corrected within two periods at the most. ,This study is one of few studies in using the econometric models to study the impact of fish production on marine trade balance and foreign direct investment.

鱼类生产，海洋贸易平衡与外国直接投资之间的长期关系

本文旨在重点检验1985-2016年间鱼类生产与两个主要变量之间的长期关系，这两个变量是阿拉伯海湾国家之一的阿曼的外国直接投资流入和海洋贸易平衡，这项研究使用了所谓的两步Engle-Granger协整检验，为变量之间的长期关系提供了证据。结果表明，鱼类生产与海洋贸易之间存在长期和短期的负相关关系平衡; 此外，任何冲击最多将在两个周期内得到纠正。，这项研究是利用计量经济学模型研究鱼类生产对海洋贸易平衡和外国直接投资的影响的少数研究之一。
