In Taiwan, secondary education links junior high compulsory education and upper secondary education. The achievement of social diversification has resulted in various conflicts and pressures. This has led to questions regarding how secondary schools should adapt to the changing environment and how to appropriately respond to the impact and challenges of numerous internal and external factors. This study explores the difficult conditions and challenges experienced by campuses undergoing ecosystem changes using multiple perspectives, namely, ecosystem theory, a policy feedback model, and the leadership theory framework. This study is divided into three main sections. First, the dimensions affecting changes in campus ecosystems are identified. Then, the reasons influencing campus ecosystem changes are analyzed. Finally, strategies for adapting to ecosystem changes are proposed.
