Public buildings involve various aspects of people's livelihood, such as cultural and sports education, science and technology, medical and health care, and administrative offices. With the continuous growth of China's economy, people's spiritual needs for health, leisure, entertainment, etc. will become higher and higher, but there are problems of lag behind developed countries and uneven distribution. Taking medical and health care as an example, China's per capita medical resources are lower than the level of developed countries, and the average urban population has more than 2.5 times the medical resources of the rural population (the three most resource-rich places: Beijing, Shanghai, and Tianjin). Therefore, the focus of the public building industry will gradually shift to second- and third-tier cities with the "spillover effect" of first-tier cities, thereby driving the development of the public building market in second- and third-tier cities.
