| هدف از پژوهش حاضر بررسی مؤلفههای مؤثر بر مدیریت تجارت آب مجازی در ایران از دیدگاه متخصصان آب میباشد که با روش پیمایشی انجام گرفت. این تحقیق از نوع تحقیقات توصیفی- همبستگی مبتنی بر مدلسازی معادلات ساختاری بود. ابزار جمعآوری دادهها پرسشنامه و جامعهی آماری نیز شامل متخصصان آب ایران به تعداد 300 نفر بود که بر اساس جدول کرجسی و مورگان (1970) حجم نمونه به تعداد 169 نفر انتخاب و به روش تصادفی ساده نمونه‌گیری شد. برای تعیین روایی پرسشنامه از پانل متخصصان گروه ترویج و آموزش کشاورزی دانشگاه تربیت مدرس استفاده گردید. همچنین، بهمنظور سنجش پایایی ابزار تحقیق از آزمون آلفای کرونباخ استفاده شد، که مقدار آن برای قسمتهای مختلف پرسشنامه بین 70/0 تا 90/0 محاسبه گردید. نتایج تحلیل همبستگی نشان داد که متغیرهای مؤلفههای سیاستی، مؤلفههای اقتصادی، مؤلفههای زیست‌محیطی، مؤلفههای اجتماعی و فرهنگی و مؤلفههای آموزشی و ترویجی با متغیر وابستهی تحقیق رابطهی معنیداری دارند. بهمنظور بررسی و برازش متغیرهای نهفته و آزمون فرضیههای پژوهش از روش مدلسازی معادلات ساختاری با نرمافزار LISREL8.80 استفاده شد. نتایج تحلیل عاملی تأییدی، پایایی و برازش متغیرهای نهفته پژوهش را تأیید کرد. مدلسازی معادلات ساختاری نیز نشان داد که متغیرهای نهفتهی بیرونی 65 درصد از تغییرات واریانس مدیریت تجارت آب مجازی در ایران را تبیین نمودند و شاخصهای برازش مدل در وضع خوبی قرار دارند. | ||

| The purpose of this study is to investigate components affecting the management of virtual water trade from water experts’ viewpoints. A survey research was conducted. This research was a descriptive- corelative research based on structural equation modelling. The data collection tool was questionnaire and statistical population included water experts (N=300). Using Krejcie and Morgan’s (1970) Table, 169 experts were selected using sample random sampling method. To determine the validity of questionnaire, a panel of experts consisting of the Department of agricultural extension and education at tarbiat Modares University was used. Furthermore, in order to assess the reliability of the research tool, cronbach's alpha test was used. The value of cronbach's alpha for different parts of the questionnaire was between 0.70 and 0.90. The results of correlation analysis showed that political, economic, environmental, social-cultural and educational-extension components had significant relationship with the dependent variable. To evaluate the Fitting Model of the latent variables and to test the research hypotheses, the structural equation modelling technique was applied through LISREL8.80 software. The results of confirmatory factor analysis confirmed the reliability and fitness of the latent variables of the research. Structural equation modelling showed that 65 percent of the changes in the distribution of Virtual water trade management were explained through external latenet variables and the indices of fitness of the model were approperiate. | ||
