چکیده مقاله :
شهرهای ایرانی اسلامی در گذر زمان شاهد تحولات و دگرگونی‌های متعددی بوده‌اند. در عصر حاضر، با پیشرفت روزافزون تکنولوژی، ضرورت ارائه خدمات الکترونیک شهری به عنوان راهکاری برای ارتقای کیفیت زندگی شهروندان بیش از پیش احساس می‌شود. در این راستا، شهر تاریخی یزد با سابقه درخشان در معماری و شهرسازی سنتی، گامی مهم در جهت ارائه خدمات الکترونیک شهری برداشته است. هدف اصلی تحقیق بررسی تأثیر زنجیره تأمین پویا بر عملکرد خدمات الکترونیک شهری در بافت تاریخی شهر یزد می‌باشد. این پژوهش از لحاظ هدف، کاربردی و از لحاظ روش تحقیق، توصیفی-تحلیلی است. برای جمع‌آوری داده‌ها از روش‌های اسنادی با ابزار کتابخانه‌ای و میدانی استفاده شده و جامعه آماری افراد آشنا به مبحث خدمات الکترونیک شهری و زنجیره تأمین پویا بوده و نمونه‌ای به حجم 250 نفر به روش نمونه‌گیری تصادفی ساده انتخاب شده است. تجزیه و تحلیل داده‌ها با نرم‌افزار Smart-PLS انجام شده است. نتایج پژوهش نشان داد که که زنجیره تأمین پویا نقشی کلیدی در ارتقای عملکرد خدمات الکترونیک شهری در بافت تاریخی شهر یزد ایفا می‌کند و شاخص‌های هزینه، قابلیت اطمینان، انعطاف‌پذیری، پاسخگویی، دارایی و چابکی به ترتیب مهمترین شاخص‌های زنجیره تأمین پویا هستند. با توجه به اهمیت این موضوع در سایر شهرهای ایرانی اسلامی، ضروری است که مطالعات مشابهی در این زمینه انجام شود تا الگویی جامع و کاربردی برای ارتقای کیفیت خدمات الکترونیک شهری در سراسر کشور ارائه شود.
Iranian-Islamic cities have witnessed several developments over time. In the current era, with the advancement of technology, the necessity of providing urban electronic services to improve the quality of life of citizens is felt more than ever. The main purpose of this study is to investigate the impact of a dynamic supply chain on the performance of urban electronic services in the historical context of Yazd city. This research is applied in terms of purpose and descriptive-analytical in terms of research method. To collect data, documentary methods with library and field tools were used, and a sample of 250 people was selected by simple random sampling. The results of the research showed that a dynamic supply chain plays a key role in improving the performance of urban electronic services in the historical context of Yazd city.
Keywords: Dynamic Supply Chain, Electronic Services, Historical Context.
Introduction
Nowadays, population growth and the increase in migration to cities have led to the uncontrollable development of urban areas, the creation of new settlements, a decrease in the level of human welfare, and the occurrence of many problems for urban managers, especially in developing countries (Delbazeh et al., 2021: 99). The historical texture of cities is a part of the country's capitals, which are not only valuable in terms of aesthetics, the continuity of collective memories, and identity, but also the place of residence of a significant part of the population of cities. The increasing growth of the dimensions of urbanization and the complexity of the nature of urban issues have caused the emphasis and attention of managers and planners to be focused more than ever on the lower levels and the full dimensions of citizens' lives.
The supply chain is the key unit of competition in today's business environment. This approach aims to improve the performance, profitability, and competitiveness of supply chain business partners. However, contemporary supply chains are exposed to various risks, including supply disruptions, supply delays, and demand fluctuations (Lin et al., 2020: 2020). Dynamic capabilities are the ability of a company to integrate and rebuild resources in order to adapt to changes in the external environment (Sadeghi & Ghasemi, 2021: 125).
The development of e-cities in the world is moving rapidly and has created many opportunities for people's living, working, and recreational environments. Providing communication infrastructure, networking, human software, security infrastructure, and the development of information institutions are among the prerequisites for the establishment of an electronic city. Creating an electronic city and stepping into the age of information technology is an undeniable opportunity. Therefore, the purpose of this study is to investigate the effect of dynamic supply chain on the performance of urban electronic services in the historical context of Yazd city.
In order to obtain a preliminary list, by reviewing the studies, the indicators have been identified and categorized and presented in Table(1).

Research Methodology
This research is applied in terms of purpose and descriptive-analytical in terms of research methodology and based on structural equation modeling based on partial least squares which has been done with Smart-PLS software. The data required for this research have been collected through documentary methods using library and field tools (questionnaires). In this research, the theoretical literature and the background of previous research were reviewed based on library studies including books, articles, and related sites. The statistical population of this study is people familiar with the topic of urban electronic services and dynamic supply chains in the historical context of Yazd city, and a sample of 250 experts of companies and organizations located in Yazd Science and Technology Park were selected by simple random sampling method and were examined by a questionnaire whose items ranged from one (very low) to seven (very high) based on Likert scale. In analyzing the obtained data, using the capabilities of SPSS, Excel, and pls-Smart software, structural equations based on variance with partial least squares method were used. In this study, in order to test the reliability of the variables, Cronbach's alpha coefficient and the combined coefficient, the extracted mean-variance (AVE) was used to calculate the validity of the variables and also to investigate the relationships of the research effect paths (t-statistic value and path alpha coefficient). It should be noted that the scope of this research in temporal and spatial dimensions is related to the winter of 1402 (2024) in the historical context of Yazd city.

Conclusion
The aim of this study was to measure the impact of a dynamic supply chain on the performance of urban electronic services in the historical context of Yazd city. In this study, using structural equation modeling and using Smart PLS software, the factors and items of dynamic supply chain and urban electronic services were identified. The results of the research showed that there is a significant, consistent and strong relationship between a dynamic supply chain and urban electronic services in the historical context of Yazd city, and urban electronic services can be explained and predicted through a dynamic supply chain (its six indicators) at the rate of 0.788. In this regard, the results have shown that the indicators of cost, reliability, flexibility, accountability, asset, and agility are the most important indicators of the dynamic supply chain, respectively, which have a significant and strong effect on urban electronic services.
