For a long time, the government's handling of public affairs has been in a relatively monopoly state. As social transformation has intensified, social governance has faced more and more challenges, and the government has been unable and unnecessary to deal with many complicated social affairs. Appeared, it is urgent to clarify the relationship between the government and the society. The society can handle it and hand it over to the society. The government only performs macro-control and supervision, which must be completed by the government itself. Services help to strip off part of the government's functions, expand the space for social self-service, enable the society to conduct self-management and self-service, and ultimately promote the improvement of the overall efficiency of society. What does this passage mean? ["Government's monopoly on public affairs hinders social efficiency.", 'Social transformation weakens the role of government in handling public affairs.', 'The transformation of government functions to services is an inherent requirement of social transformation.', 'Purchasing public services is the primary way for governments to improve efficiency in the future.']
