چکیده

در این بررسی به منظور ارزیابی عوامل مؤثر بر انتخاب مصرف کنندگان شهر اصفهان برای خیار معمولی، سالم و ارگانیک از روش انتخاب تجربی و مدل لاجیت چند گانه استفاده گردید. در مدل انتخاب تجربی جهت طراحی سناریو از روش رتبه بندی مشروط استفاده شد. داده ها و اطلاعات مورد نیاز از طریق پیمایش های میدانی، با طراحی و تکمیل پرسش نامه پژوهش گر ساخته به روش نمونه گیری انتساب متناسب طبقه ای از 230 مصرف کننده در سال 1392 جمع آوری شد که به منظور آزمون پایایی ابزار پژوهش، تعداد 30 پرسشنامه برای انجام آزمون مقدماتی در منطقه مورد مطالعه توزیع گردید و با میانگین آلفای کرونباخ 74/0 به دست آمده، اعتبار آن تایید شد. اولویت‌بندی ترجیحات مصرف‌کنندگان نشان می دهد که به ترتیب 1/77 درصد محصول سالم، 4/12 درصد محصول ارگانیک و 1/10 درصد محصول معمولی را اولویت نخست انتخاب خود می دانند. نتایج حاصل از مدل رگرسیونی نشان داد که عواملی چون درآمد، اطلاع از ویژگی های محصولات سالم، اهمیت به سلامتی و حفظ محیط محیط زیست و وجود فرد سالمند و بیمار در خانواده، اثر مثبت و معنادار بر انتخاب محصول سالم و ارگانیک دارند. باارتقاء سطح آگاهی مصرف کنندگان از مزایای مصرف محصولات سالم و همچنین تغییر نگرش آنان در زمینه اهمیت حفظ سلامتی‌شان می توان در جهت بهبود سلامت جامعه و محیط زیست گام برداشت.
