dc.description.abstractCountries participate in regional trade blocks to enhance their trade activities and trade performance. This study proposes a novel approach to trade performance assessment, introducing innovations both in terms of performance parameters and methodology. From a performance parameter perspective, the inclusion of sustainable development and economic diversity levels in trade performance evaluation differentiates this study from traditional trade performance measurement approaches. From a methodological perspective, a hybrid model that simultaneously considers both subjective and objective criterion weighting based on expert opinions is introduced. The spherical fuzzy (SF)-simple weight calculation (SIWEC)-symmetry point of criterion (SPC)-opportunity losses-based polar coordinate distance (OPLO-POCOD) model, developed as a decision support system, is proposed for evaluating the trade performance of country blocs. SF-SIWEC is employed as the subjective criterion weighting method, while SPC serves as the objective criterion weighting method. The OPLO-POCOD alternative ranking method is employed to calculate the trade performance of countries. The proposed methodology is applied to the Organization for Economic Cooperation and Development (OECD) countries. According to the subjective weighting method, "sustainable development (0.0978)" emerges as the most important criterion, whereas in the objective weighting method, "number of product types (export) (0.1612)" is identified as the most significant one. In the final criterion weights, "number of product types (export) (0.1232)" is also determined to be the most important criterion. Considering the final criterion weights, the United States (0.9871) has the highest trade performance among the OECD countries. Thus, when both sustainability and economic diversification are considered, it is understood that the most influential criteria in determining multidimensional trade performance are the number of exported product types and sustainable development. From this perspective, the United States stands out as the country with the highest multidimensional trade performance among OECD countries. This study contributes to the literature by integrating sustainability and economic diversification parameters into trade performance measurement as well as proposing a comprehensive methodology for performance evaluation in trade blocs.
