下面我们将谈一下美国的政治制度，美国是一个联邦国家，其政权组织的形式为总统制，并实行三权分立的政治体制以及两党制的政治政党。美国的宪法规定了美国的政治制度的基本原则，包括人们的自然权利，民主权，和政治权。总统制：总统是国家的元首，三权立法，行政和司法分别在国会，总统和法院负责。当三个部门分别行驶权利的时候，他们可以互相制约，实现权利的平衡。国会议员：由一百多人组成，每个洲的选票，每个人的选票都体现了平等的原则，参议院由四百多名成员参加，其中根据各州的人口选择不同的数字，只有国会才有宣战的权利，总统是有民间选举产生的，选民是由各州选举的代表来进行选举。国会有立法权，但是总统可以否定国会的立法。然而国会也可以推翻总统。在美国的政治体系中，权利分离，可以保证平等和公平性，也可以调动各部门的积极性，政府无权干涉执法部门，这种类型的美国政府，直接显示了人民的意愿。

Next, let us talk about the political system of the United States. TheUnited Statesis a federal state, whose regime organization form is a presidential system, and it practices the political system of Separation of the Three Powers and counterbalance combination, as well as a political party of the two-party system. The U.S. Constitution provides the basic principles of the American political system, including: man’s natural right, natural rights, popular sovereignty and the right to limit government, non-legal rule of man, representative system, separation of powers and checks and balances, federalism, civilians’ power to control the military. As for the Presidential system: The president is head of the state and head of the government. The principle of implementing separation of powers and checks and balances: The three rights legislative, administrative and judicial are respectively in charge of the congress, the President and the courts. They can restrict each other to achieve the balance of power when the three departments exercise their rights. State legislative attributed the Congress, and the senate is composed of 100 people. Each state votes two persons to embody the equality between each state. The House of Representatives has 435 members at present, of which the corresponding number is selected according to the states population. Only the congress has the right to declare war in the separation of powers. President is elected by voters indirectly: the element of Electoral College to elect President is the corresponding number of voters who are selected by states. The President does not need to be responsible for the congress because the congress does no help with the electing. The congress has the legislative power and the president can veto the bill which is passed by the congress; however, the congress also can authorize to override the president’s veto under certain conditions. In America’s political system, the separation of powers can make every department become uncaused and can fully mobilize the enthusiasm of each department. The government has no right to interfere with the independent actions of the judicial department. This type of regime in the United States directly shows the citizens’ wishes. The citizens can be directly involved in the political life and help to solve questions for the country, which all reflect the direct democracy [Andrew, H (2007)].

By comparison, firstly, we can know that the United States’ political system is more complete than China’s political system and its legal system is better than that of China’s. So I think the United States has more constrains, and the United States’ market has more standards, for the political system in the United States is so mature. It is difficult to get lots of profits under these conditions and restrictions. In contrast, the market system in China is less perfect, and many areas have no clear rules and laws; there will be fewer restrictions on business, so it is easy to obtain more profits.
