Abstract

Currently, rice production in the Mekong Delta region accounts for more than 50% of Vietnam?s total paddy production and 90% of its rice export volume. Therefore, increasing the efficiency of rice production systems and enhancing the comparative advantage of Vietnam?s rice industry have been an important focus area for policy makers and researchers for many years. Access to credit has been identified as a key factor for improving rice production. This fact is validated in this study by considering the production and technical efficiency levels of rice production for a sample of farmers in the Mekong Delta. The study focuses particularly on the effects of both formal and informal credits on production levels and production efficiency by using a Stochastic frontier analysis and a quantile regression. The results confirm the positive influence of credit on production and production efficiency. Both formal and informal credit appear to be important. JEL: E5, G2, O2
Keywords: Stochastic frontier analysis, quantile regression, access to credit, rural households

Tóm tắt

Gần đây, sản xuất lúa ở đồng bằng sông Cửu Long (ĐBSCL) chiếm hơn 50% tổng sản lượng lúa ở Việt Nam và 90% sản lượng xuất khẩu. Vì vậy, tăng cường hiệu quả hệ thống sản xuất lúa và nâng cao lợi thế so sánh ngành công nghiệp lúa gạo của Việt Nam là một lĩnh vực tập trung quan trọng cho nhà nghiên cứu và người làm chính sách nhiều năm qua. Tiếp cận tín dụng được xác định là nhân tố quan trọng để phát triển ngành lúa gạo. Thực tế này có giá trị ở nghiên cứu này thông qua việc xem xét mức độ hiệu quả kỹ thuật và sản xuất lúa cho nông hộ ở ĐBSCL. Nghiên cứu này tập trung đặc biệt vào tác động của tín dụng chính thức và phi chính thức lên mức độ sản xuất và hiệu quả sản xuất qua việc sử dụng mô hình Phân tích giới hạn ngẫu nhiên (Stochastic Frontier Analysis) và Mô hình phân vị (Quantile Regression). Kết quả này củng cố tác động thuận của tín dụng lên hiệu quả kỹ thuật và sản xuất lúa. Cả tín dụng chính thức và phi chính thức đều có vẻ quan trọng.
Từ khóa: Stochastic frontier analysis, quantile regression, tiếp cận tín dụng, nông hộ
