ABSTRACT
To implement the transit priority policies, governments in many cities have issued a series of relevant policies and measures. One important measure is to combine low fares with large financial subsidies. In other words, governments purchase public services from businesses through financial subsidies.

1 INTRODUCTION
With China’s urbanization and mechanization pressing ahead, cities continue to expand, and urban population and traffic volume increase rapidly. As a result, traffic congestion, security issues, environmental pollution and energy depletion are increasingly prominent, becoming the bottleneck of urban sustainable development and imposing great pressure to the construction of a resource-conserving and environment-friendly society. Urban public transit possesses advantages such as high holding volume and efficiency, and low energy consumption and pollution. Learning from Europe, Japan, Singapore and South America, China is striving to prioritize public transit to reduce environmental pollution and energy consumption, and to achieve low carbon and sustainable development.
