Brief Analysis of the Externality of the Government Behavior and its Economical Function

The externality of government behaviors is a by-product in the process when the government makes the public policy and exerts the function of public service to make up for the defects of the market. It is produced by political process. Through changing the trade principles or the control of the ownership, it can change the externality of the market indirectly, and causes transference of the corresponding cost and profit. In the new phase of the reform, it is of great importance to understand the externality of the government behavior fully, which will do good to accelerating the political frame reform and perfecting the socio-economic management in China.
