CHƢƠNG 5 : KẾT LUẬN, GIẢI PHÁP VÀ HẠN CHẾ CỦA ĐỀ TÀI
5.3. Hạn chế của nghiên cứu
Mặc dù đã cố gắng rất nhiều, nhưng theo tác giả, đề tài vẫn còn một số hạn chế. Về mặt số liệu thống kê, ước lượng mơ hình: vì chỉ tiêu nợ cơng là một chỉ tiêu khó tổng hợp đầy đủ và chính xác ví dụ như đối với các khoản nợ vay nước ngoài của các con nợ không cư trú ở nội địa, nợ của chính quyền địa phương...rất khó thu thập. Nên kết quả ước lượng có được trong nghiên cứu có thể sẽ khơng chính xác. Do thống kê tài chính trong nước khơng đầy đủ và rất khó tiếp cận nên nghiên cứu sử dụng số liệu từ các tổ chức tài chính quốc tế nên có thể sẽ có một số điểm khác biệt với các số liệu báo cáo trong nước, điều này có thể do phương pháp, cách phân bổ khác nhau và khái niệm về nợ công giữa các tổ chức khác nhau không thống nhất.
Thực tế qua số liệu thống kê trong nghiên cứu này, tỷ lệ nợ công trên GDP của Việt Nam theo WB tổng hợp trong những năm gần đây chỉ xoay quanh mức 40%-50%. Qua số liệu của cả giai đoạn 1986-2013, ngưỡng nợ cơng tìm được tại mơ hình là
62,61%. Trong khi đó, trên các phương tiện thơng tin đại chúng và số liệu phổ biến trên các trang mạng điện tử lại cho rằng nợ cơng Việt Nam có khả năng đạt đến mức 100% nếu tính đầy đủ tất cả các khoản nợ của doanh nghiệp nhà nước khơng được Chính phủ bảo lãnh nợ và nợ đọng xây dựng cơ bản.
Mẫu quan sát tương đối nhỏ (27 quan sát, theo số liệu năm 1987 - 2013), nếu số liệu của Việt Nam được phản ảnh theo quý, thì số mẫu quan sát nhiều hơn và kết quả đo lường kinh tế lượng sẽ chuẩn xác hơn.
