Tóm tắt

Nghiên cứu này là một phân tích đa quốc gia về năng suất của ngành nông nghiệp tại các quốc gia châu Phi cận Sahara (SSA) trong giai đoạn từ 2010 đến 2017. Nghiên cứu đã áp dụng thiết kế mô tả. Kích thước mẫu bao gồm ba mươi tám (38) quốc gia châu Phi cận Sahara. Việc thu thập dữ liệu cho nghiên cứu này liên quan đến việc thu thập các yếu tố đầu vào và đầu ra nông nghiệp từ năm 2010 đến 2017 từ các báo cáo của Ngân hàng Thế giới và Liên Hợp Quốc. Nghiên cứu đã sử dụng Phân tích Bao phủ Dữ liệu (DEA) và phân tích hồi quy bảng để xác định và đánh giá các điểm số hiệu quả cho từng đơn vị ra quyết định (38 quốc gia SSA) và để xác định các nguồn lực cụ thể có đóng góp đáng kể nhất vào sản lượng sản xuất được đưa vào nghiên cứu. Kết quả tiết lộ rằng 9 quốc gia SSA (có tỷ lệ 23,68%) hoàn toàn hiệu quả về mặt kỹ thuật trong việc sử dụng các đầu vào nông nghiệp để tạo ra đầu ra trong khoảng thời gian từ 2010 đến 2017. Một vài quốc gia khác chỉ đạt hiệu quả kỹ thuật trong một khoảng thời gian ngắn từ 2010 đến 2013. Các kết quả thống kê cũng chỉ ra rằng một số quốc gia SSA không hiệu quả về mặt kỹ thuật từ 2010 đến 2013, nhưng từ 2014 đến 2017, họ đã duy trì hiệu quả kỹ thuật một cách liên tục. Theo các phát hiện, nghiên cứu đã thiết lập những tác động quan trọng để thúc đẩy lý thuyết và thực tiễn về năng suất nông nghiệp.
