Từ những hạn chế nêu trên, các bài viết và nghiên cứu về lĩnh vực lợi nhuận của CTBH nên mở rộng lấy mẫu cho toàn bộ CTBH tại Việt Nam và thời gian nghiên cứu dài hơn, đồng thời số liệu được lấy từ những tổ chức uy tín để có kết quả phân tích chính xác hơn.
Bên cạnh đó, trong nghiên cứu tác giả chỉ đề cập tới một số yếu tố tiêu biểu, còn nhiều yếu tố tác giả chưa đưa vào bài viết. Các nghiên cứu sau có thể tìm hiểu và bổ sung những yếu tố như chi phí quản lý, đòn bẩy, lãi suất, thất nghiệp, chính sách kinh tế của nhà nước.
