The infrastructure is an important guarantee of regional economies and social development，basic public service is the important support to satisfy peoples’ daily life and all-round development. In recent years，Sichuan province continues to increase urban and rural infrastructure investment and basic public service supply，but in between county towns，rural and urban areas in whole province at present stage，the inefficient and unbalance supply of infrastructure and public service is the objective reality. Accordingly，speeding up infrastructure construction and improving the level of basic public service supply constantly has a great practical significance to ensure the rapid speed of urban and rural economies and social development，to meet the needs of urban and rural residents in the production and life，to build a well-off society in an all-round way in 2020.
