چکیده

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.
