The Index, jointly developed by the Development Planning Department of the National Development and Reform Commission and the Cloud River Urban Research Institute, is the most scientific, international and practical index concerning the development of Chinese cities I have ever seen. It is a comprehensive "health check-up report" for Chinese cities. Every city evaluated by the Index can find its "diseases" and get a treatment plan. The "health check-up report," released on an annual basis, will add more indicators, identify new situations and spot new problems.

Urbanization provides enduring impetus to China's economic and social development, and China's urbanization has a long way to go. At the same time, China's economy has transformed to the phase of high-quality development. Urbanization and high-quality development are converged. Cities are main players in economic development, and also spatial carriers of high-quality development. China's high-quality development as a whole hinges on high-quality development of Chinese cities.

The China Integrated City Index provides an evaluation of urban development from the environmental, social and economic perspectives, and embodies the idea of spatial balance. That is why I say it is a truly comprehensive and genuine evaluation of development. Only in this way will the evaluation of urban development be scientific and conducive to guiding the development of cities in a more comprehensive, coordinated and sustainable manner.

China's urban development must adhere to the philosophy of ecological civilization, promote green development, circular development and low-carbon development, and minimize the interference with and damage to the nature, while promoting the economical and intensive utilization of resources including land, water and energy. Much attention should be paid to eco-safety, and the ratio of green and ecological spaces, such as forests, lakes and wetlands, should be increased, in order to enhance the water conservation capacity and environmental capacity. The quality of environment should be improved, by reducing emissions of major pollutants, controlling over the intensity of development, and increasing the capability to withstand and mitigate natural disasters. The China Integrated City Index provides a number of implementable green indicators. All cities should check for their gaps from the indicators and find out the areas to work on for urban development. In this regard, the China Integrated City Index is not only an evaluation, but also points out the direction for future development.
