The article origins from the general theories of the air defense identification zone system, combines with the practice of the representative countries worldwide, and develops through a variety of ways including historical analysis, literature analysis and comparative analysis. It eventually reaches the following conclusions:EEZ airspace residual rights are the best perspective to study the air defense identification zone system, which provide a perfection direction for the domestic legislation and the theoretical basis that the system is able to develop into international space law. The article is divided into four parts:the first part analysis the general theories including the concepts of the air defense identification zone and the differences between which and the related fields, the second part focuses on the practice of States, the third summarizes the latest guiding trend in the exclusive economic zone of airspace residual rights, he fourth part reaches reasonable and innovative proposals. Each chapter identify problems, analyze problems, put forward problem-solving ideas, and make reference to observations to improve air defense identification zone. |
