Efficiency Analysis of Eu and Non-Eu R&d Investor Firms on Matched Samples
(Springer, 2023) Belgin, Onder
This study is on the efficiency analysis of EU and non-EU R&D investor firms. The study mainly aims to understand if there is a difference between the efficiency level of EU and non-EU R&D investor firms and what the effecting factors of firm efficiency are. To construct an unbiased group of EU and non-EU firms, propensity score matching (PSM) is employed and thereby the analysis is made with the firms that have similar features. In the efficiency analysis stage, a slacks-based measure data envelopment analysis (SBM DEA) model is used for 2017-2019 period. After that, a panel Tobit regression model is used to examine the factors effecting the efficiency of the EU and non-EU firms. The results showed that EU firms have higher efficiency than non-EU firms only in 2018 and EU firms have very high improvement potential in market capitalization. By panel Tobit regression model, it was understood that capital expenditure intensity has negative effect on both the efficiency of EU and non-EU firms. Size of the firms has negative effect on only non-EU firms.
The Relationship Between Operational Efficiency and Financial Efficiency in the Shipping Industry: An Example From Privatized Ports in Türkiye
(EDP Sciences S A, 2025) Kaya, Ebru Nur; Mete, Mevlut Hurol; Belgin, Onder
Since the ports are the backbone of international trade they need to be managed efficiently. This study addresses to analyze the operational and financial efficiency of the selected privatized ports that have been belonged to TCDD (Republic of T & uuml;rkiye State Railways). For this purpose, EATWOS (Efficiency Analysis Technique with Output Satisfying) method is employed, and the weights of the inputs and outputs are determined using LOPCOW (Logarithmic Percentage Change-Driven Objective Weighting), MEREC (Method Based on the Removal Effects of Criteria), and CRITIC (Criteria Importance Through Intercriteria Correlation) methods. After obtaining the weights from these objective methods, the comprehensive weights are calculated using TPOP (Technique of Precise Order Preference) method. Finally, Spearman's rank-order correlation shows that there is no relationship between the operational and financial efficiency of the ports. The number of studies that address both operational and financial efficiency of ports is limited, and this study distinguishes itself by investigating the relationship between both efficiency types.
