  • Smart city has effect toward its sustainability. Citizens should be viewed as co-creators of cities, not consumers. From this point of view, citizen responsibility and ethics should be emphasized. Now, Smart cities are becoming more important than ever. From now on, urban development is divided into two major categories. One side is the development based on smart city, and the other is urban development that revives the old city. As the city grows bigger and bigger, many problems arise and there are many problems. This tendency must become stronger in the future. But, Stones shall be dressed to exact size and shapes before being laid. Until now, No attempt has been made to declare about Citizen Spirit in Fourth Industrial Revolution. In the era of the Fourth Industrial Revolution, in order to become a leading country of Smart City, we must first complete the spiritual revolution. From this aspect, this study proposes the "Declaration of the Fourth Industrial Spirit Revolution".
