<span lang="EN-US">The major goal of this research paper is to investigate the relationship among Turkish Economic growth, airway transportation and FDI. Several research results consistent with this papers finding and it has been founded that the economic growth plays a crucial role in air transportation by implementing econometrical models including Multiple Linear Regression (MLR), Johansen co-integration test and VAR model. The variables have been put into the Vector Autoregressive Model (VAR) and Johansen co-integration test. According to the test result of Johansen co-integration test there is a long-term relationship between the variables of GDP, FDI and air transportation. According to the both variance decomposition and Impulse Response analysis, the effect of GDP is found to increase </span><span lang="EN-US">air transportation</span><span lang="EN-US"> more than the FDI. Finally, the contribution of Turkish economy to civil aviation seems significant which is consistent with this paper’s research results.</span>

Today, the processes of restructuring the railway sector and the liberalization of the railway market change significantly. Vertical separation between infrastructure railway transportation service provision and train operations is a significant key element in the railway liberalization. This paper focuses on a research into railway regulation and liberalization in 30 countries. The aim of this paper is to give a comparative overview of the regulation of railways and analyses the process of the liberalization and restructuring of railways in the 30 countries. We test this theoretical prediction using a data base that contains investment in transport with private participation, transport services information from World Bank. Our final results are valid for the period 1980-2014. Overall, the analyses showed statistically significant interaction effects between railways transportation and transport services and investment in transport with private participation. This study presents new insights in theory, paving the way for further research.

Purpose-Ports have a leading role on affecting country and regional economy with the development of international trade. With the world trading volume increasing day by day the performance of ports and terminals, which provide export, import, transit, local or regional transportation services, must be examined regularly in order for their maximum capacity to be utilized. Furthermore, due to the high costs of infrastructure and superstructure investments of container ports, long term plans and strategies are required. This study aims to evaluate the performance of 20 container ports operating in Turkey by examining the performance criteria of container ports in the world. Methodology-For this reason, when calculating the maximum capacity utilization of the ports, the main principle is to examine the effective utilization of all the inputs using various methods. In this study, the performance of 20 container ports operating in Turkey, has been analysed with the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method, using non-financial data from 2015. Findings-As a result of the analysis, the values that show the overall performance of the ports were converted into a single score with the help of the TOPSIS method and port performances were evaluated by comparatively examining the results obtained. Mersin port, Ambarlı Marport and Kumport derived first with the highest performance. Conclusion-Port performance measurement has an important requirement for maritime transport. The high performance of container ports improve the productivity of the production such as labour and capital.
