Ship investment strategies in fluctant shipping market condition: Turkey's perspective
Maritime transport has become the way of carrying the greatest amount of world trade, which has been the case in recent years. In maritime trade, ports are the most important points that logistics opens up to international routes.

Regression analysis, which is one of the quantitative research methods, was used to measure the relationship between this index and the "Economic Openness Index", which was developed to measure the economic vulnerability of the countries involved in global trade and which was obtained by calculating the total export, import and gross domestic product of countries.

In addition to the general development of the country, it is predicted that maritime trade is one of the factors that will enable trade to be least influenced by the fluctuations in the global crisis and uncertainty period and this study aims to create a one-way model for the development of maritime logistics networks from every direction. Increasing port capacities and developing new logistic services for our students in line with the coastal structure of our country will be a bridge to provide a competitive advantage for our country in international global markets. In the near future, logistical networks, maritime and port development issues will be a requirement for the protection of our country's level of economic stability and prosperity in times of global crisis.

The effects of the Customs Union on Turkish foreign trade and foreign trade legislation
Looking at the history of the world, the trade policy of the states among each other; the colonial-imperialist state understanding that the powerful states were taxed by the weak, the tax measures they applied to each other if the two states were strong, or the tax privileges they had given each other. However, these policies have sometimes been economically disadvantageous to other states, including both parties to an agreement, sometimes both, or contracted parties. The political and economic disputes that lived until the end of World War II led to great destruction in the states. With the concern that the neighboring state of Soviet Russia would be exposed to communism and the US view this as a danger and that this danger could only be overcome with a united Europe, the European idea to unify emerged, with the material and intellectual support of the United States has been thrown away. Our work will first examine the explanations, causes, types, success conditions and integration tendencies in the world of economic integration theory and then examine the effects of the Customs Union Theory, one of the types of economic integration theory. It will be briefly mentioned from the history of the European Union, the institutions and organizations that our country has made a Customs Union agreement, and the process of entry into the Customs Union of our country will be mentioned.

Finally, the Customs Union Agreement, which entered into force in 1996, examines our foreign trade data with the innovations brought about by our foreign trade legislation, and the impact on the Turkish Foreign Hades will be revealed. ii Keywords: Economic Integration, European Union, Custom Union, Turkish Foreign Trade
