نقش اعتماد و تعهد بر عملکرد زنجیرۀ تامین پایدار با میانجی ‎‍گری انعطاف‎‍پذیری عرضه (مورد مطالعه: صنعت پتروشیمی)

هدف پژوهش حاضر، مطالعۀ تاثیر اعتماد و تعهد بر عملکرد زنجیرۀ تامین پایدار شرکت‌های‌ فعال در صنعت پتروشیمی ایران، با در نظر گرفتن نقش میانجی انعطاف‎‍پذیری عرضه است. ابزار گردآوری داده‎‍ها پرسش‌نامۀ استاندارد است و جامعۀ آماری، مدیران ارشد زنجیرۀ تامین پتروشیمی کشورند که تعداد نمونه با استفاده از فرمول کوکران 119 نفر تعیین شد. پرسش‌نامه‎‍ها به روش نمونه‎‍گیری تصادفی ساده توزیع و در‌نهایت از 108 پرسش‌نامه برای تحلیل‌ استفاده شد. پژوهش حاضر از‌لحاظ هدف کاربردی، روش آن توصیفی و از نوع پیمایشی است و نتایج به ‌روش‌ حداقل‌ مربعات‌ جزئی استخراج‌ شده‌ است. یافته‌ها‌ نشان‌ می‌دهد‌ اعتماد و تعهد و انعطاف‎‍پذیری عرضه بر عملکرد زنجیرۀ تامین پایدار، تاثیر مثبت دارند. مطابق با نتایج، زمانی که اعضا به تامین‌کنندگان خود اعتماد دارند و دارای راهکارهایی برای حل مشکلات و تطبیق با تغییرات‌اند (انعطاف‌پذیری عرضه)، تعهد به ارائۀ یک عملکرد پایدار بهبود می‌یابد. با تشریح رابطۀ بین اعتماد و تعهد با انعطاف‎‍پذیری عرضه و تاثیر آن بر عملکرد زنجیرۀ تامین، این پژوهش‌ به فهم بهتری از طراحی و مدیریت زنجیرۀ تامین پایدار در صنعت پتروشیمی کمک می‌کند.

studying the influence of trust and commitment on sustainable supply chain performance considering the mediating role of supply flexibility the case of the petrochemical industry

purpose: trust and commitment in the economy of production are considered vital concepts for the development of companies in the petrochemical supply chain. such companies can achieve sustainable performance by being capable of supply flexibility and continuously promoting trust and commitment among their partners. this study aims to investigate the influence of trust and commitment on the performance of the sustainable supply chain in the iranian petrochemical industry, taking into account the mediating role of supply flexibility.design/methodology/approach: the data collection tool was a questionnaire, and the statistical population included the senior managers of the petrochemical supply chain. the sample size has been determined 119 respondents, based on cochran’s formula. questionnaires have been distributed through a simple random sampling method. the current research is typically descriptive and survey-based and the results have been analyzed using the partial least squares method.findings: findings indicated that trust commitment and flexibility of supply had a positive influence on the performance of the sustainable supply chain. also, supply flexibility played a mediating role in the impact of trust and commitment on sustainable supply chain performance.research limitations: although the data generally supported the proposed model of this research in the petrochemical industry, one of the potential limitations was related to the selection and sample size. this limitation can change the amount of explained variance and cause bias in the results.practical implications: according to the results, when members trust their suppliers, have strategies to solve problems, and adapt to changes (supply flexibility), the commitment to provide sustainable performance improves. by describing the relationship between trust and commitment to supply flexibility and its influence on supply chain performance, this research helps to understand the design and management of sustainable supply chains better in the petrochemical industry.social implications: supply flexibility as a mediator in the relationship between trust and commitment has an essential impact on supply chain performance. by confirming this hypothesis, supply flexibility acts as an influencing factor in improving sustainable supply chain performance. providing an infrastructure capable of promoting trust and commitment in the supply chain facilitates improved supply flexibility and, thus, improved sustainable supply chain performance. suppliers and other members of the supply chain should review and evaluate their capabilities in supply flexibility.originality: investigating the influence of trust and commitment on the performance of the sustainable supply chain, considering the mediating role of supply flexibility in the petrochemical industry indicates that such factors have a significant impact on the performance and sustainability of the supply chain in this industry.
