The prism model theory was founded by Gus, a famous contemporary American management scientist. "Prism model theory" divides social forms into three basic models, namely agricultural society, prism society and industrial society, and then compares their respective characteristics and the influence of social environment on administrative system.

The agricultural society that Riggs said is similar to the traditional society, the industrial society is equivalent to the modern society, and the prismatic society is a transitional society. The concept of prism society is not only an important contribution of Riggs, but also his theoretical feature.

Riggs' masterpieces and theories

Administrative Ecology is the most important representative work of Riggs and the most important work in the field of administrative ecology.

In this book, Riggs takes traditional Thailand, modern Thailand, the Philippines and modern America as objects, and systematically expounds his own views on administrative ecology by analyzing their respective socio-economic structures and the interaction among culture, history and public administration. Conclusion: When we study the administrative system and behavior of a country, we should not only describe and compare the administration itself in isolation, but also further understand its relationship with the surrounding environment.

Riggs believes that in developed countries, economic, political, administrative and other social aspects have their own scope to some extent, so it is easier to study them separately. However, in developing countries, these aspects are often intertwined and closely influenced. Therefore, it is necessary to study the relevant factors of the whole social and political system in order to outline the real situation of public administration.
