Nowadays, supply chains are highly vulnerable and prone to various risks due to geographical expansion and the complexity of communication networks. Sustainability in supply chains is increasingly seen as part of supply chain management. Sustainability has become a necessity, and every supply chain needs sustainability. However, the supply chain has a breadth and complexity of indicators. This paper aims to provide a model for evaluating the impact of the sustainable supply chain on organizational performance and efficiency in the National Iranian South Petroleum Company (NISOC). This study consists of two quantitative studies and a qualitative stage by designing several questions and using a mixed research method. The qualitative stage uses grounded theory methods following a systematic review of the literature on sustainable supply chain management and its adaptation to the local needs of the sustainable supply chain in one of the country’s largest oil companies. The statistical population of the research includes all employees of the NISOC with an unlimited number, of which 384 subjects are randomly selected as samples. In this study, a questionnaire is used as the data collection tool. The questionnaire designed in this research is based on a 5-point Likert scale. Options range from strongly agree to disagree strongly. The research hypotheses are tested using SmartPLS software. According to the results, the organizational performance and efficiency in the NISOC are affected by the green supply chain, industry supply chain, macro policies, socioeconomic factors, organizational factors, political factors, technology, manufactured products, customers, and supply chain failures. As shown in this study, using sustainable approaches to the supply chain of the petroleum company improves the situation of this organization and increases its effectiveness and efficiency. Further, the performance of individual components of organizations increases due to the sustainability model in this company

The paper focuses on regional trade agreements and economic co-operation and develops a new appropriate approach to study their impact on growth and trade. The approach is based on an endogenous trade-growth theory and novelly specified in an economic integration (expenditure) framework which is the conceptual foundation of regional trade agreements. Importantly, it also appropriately takes into account major add- and sub-factors as recommended by Johansen, the computable general equilibrium pioneer, in practical economic planning and policy modelling. Applications of the approach to China, a key member of the Regional Comprehensive Economic Partnership agreement group, are also reported to provide useful insights for suitable evidence-based impact analysis. The analysis has relevance to such trading blocs as BRICS and the 21-member Indian Ocean Rim Association where Iran is a key member. Policy implications from the findings are then briefly discussed.

  The paper uses economic and energy data analysis and econometric modeling to study the prospects and challenges of Korea€™s 2003 FTA Roadmap (MOFAT 2013) in the form of potential comprehensive partnerships with its major trade and energy partners. It first reviews Korea€™s international economic and trade relations in recent years with a focus on its major merchandise export destinations and energy imports, and their association with the country€™s economic performance. A causal model of endogenous growth, gravity trade and energy imports for Korea in an economic integration theory framework (Tran 2012 Tran and Limskul 2013) is then developed to investigate the structural effects between these sectors. Empirical findings by system estimation are finally used to provide predictive policy implications for comprehensive partnerships between Korea and major resources-rich countries in the Middle East and potentially Iran.
