ملخص المقالة :
تحقیقات به عنوان راهبردی مناسب برای افزایش تولید و عرضه محصولات کشاورزی و رفع فقر و کمبود مواد غذایی می‌باشد.تحقیقات به اشکال گوناگونی بر تولید و بهره‌وری بخش کشاورزی اثرگذار می‌باشد. سرریز تحقیقات از سایر بخش‌ها و کشورها، بخش مهمی از ارتقای بهره‌وری بخش کشاورزی را در برمی گیرد. در این پژوهش با استفاده از روش حداقل مربعات و الگوی وقفه‌گیری آلمون، به بررسی و ارزیابی اثر تحقیقات و سرریزهای آن برای سال‌های 1339 تا 1391 پرداخته شد. نتایج نشان می‌دهد که کشش تحقیقات بخش کشاورزی 311/0، تحقیقات سایر بخش‌های اقتصادی 109/0، تحقیقات ناشی از کالاهای وارداتی سرمایه‌ای، 057/0 و تحقیقات ناشی از کالاهای وارداتی واسطه‌ای 0462/0 می باشد. ضریب جابجایی عرضه ناشی تحقیقات بخش کشاورزی 193/0، تحقیقات سایر بخش‌های اقتصادی 068/0، تحقیقات ناشی از کالاهای وارداتی سرمایه‌ای، 035/0 و تحقیقات ناشی از کالاهای وارداتی واسطه‌ای 029/0 برآورد شده است. بنابراین تحقیقات بخش کشاورزی، بیشتر از تحقیقات سایر بخش‌ها (سرریزها) بر بهره‌وری بخش کشاورزی اثرگذار می‌باشد.
