Tóm tắt

Bài báo này nghiên cứu cách các công ty có thể sử dụng sức mạnh tổng hợp để tối ưu hóa danh mục công nghệ thông tin của họ. Chúng tôi bắt đầu bằng việc xây dựng một khung lý thuyết cho việc lựa chọn danh mục bằng cách xác định ba loại sức mạnh tổng hợp trong công nghệ thông tin. Tiếp theo, chúng tôi sử dụng khung này để xem xét tác động của các loại sức mạnh tổng hợp khác nhau đến việc lựa chọn danh mục. Các mô hình phân tích được phát triển để minh họa vai trò của từng loại sức mạnh tổng hợp, và các phương pháp phân tích và tính toán được sử dụng để điều tra tác động của sức mạnh tổng hợp. Phân tích trong bài báo này cung cấp các điều kiện mà trong đó việc tăng cường sức mạnh tổng hợp dẫn đến một danh mục hiệu quả hơn hoặc kém hiệu quả hơn. Nghiên cứu của chúng tôi xác định rằng các công ty có ngưỡng rủi ro cao hơn có khả năng thu được các danh mục công nghệ thông tin hiệu quả hơn bằng cách tăng cường sức mạnh tổng hợp, trong khi các công ty có ngưỡng rủi ro thấp hơn ít có khả năng hưởng lợi từ việc tăng cường sức mạnh tổng hợp.
