چکیده

امنیت غذایی، یکی از محورهای رشد و توسعه اقتصادی و از اهداف مهم هر کشور محسوب می­شود. با توجه به اهمیت بخش کشاورزی در امنیت غذایی، در این مطالعه، با استفاده از شبکه بیزین به بررسی تأثیر بهره­وری کشاورزی و محیط کسب و کار بر شاخص تولید غذا در ایران در دوره زمانی 1381-1396 پرداخته شد. نتایج نشان داد متغیرهای بهره­وری کشاورزی و محیط کسب و کار تأثیر مثبت بر شاخص تولید غذا دارند. همچنین، نتایج تحلیل حساسیت شبکه بیزین نشان داد بیشترین متغیر تأثیرگذار بر شاخص تولید غذا، متغیر بهره­وری کشاورزی و پس از آن بهره­وری آب در بخش کشاورزی می­باشد. بنابراین، اعمال سیاست هایی به منظور کاهش هزینه تولید، افزایش بهره وری تولیدکنندگان محصولات کشاورزی و تشویق سرمایه گذاری بخش خصوصی در بخش کشاورزی، می­توانند در جهت هدفمندسازی سیاست های حمایتی بخش کشاورزی در راستای امنیت غذایی مؤثر باشند.
