Different international trade theory to guide the practice of foreign trade, will produce a wide range of specific trade policies and measures. Free trade theory suggests that it should try to eliminate obstacles to trade development measures, such as reductions in tariffs and non-tariff barriers and trade protection theory is that should be based on the needs of its industrial development, there is mining duties and other non-tariff measures to restrict certain products imports, encourage the export of certain products. Various policy measures impact on imports and exports is not the same, what kind of measures to adopt, or in combination of several measures to achieve target certain areas, we need to make a special research and analysis. Practice of modern international trade show, both on the international trade market there is competition, but also there is the use of different countries. So by different countries will sign various agreements, treaties or participate in certain international economic organizations to constrain their behavior and norms. These agreements, treaties and international economic organizations exactly how many Member States will bring concrete economic benefits or losses, usually requires researchers conducted a special analysis. The facts tell us that the international economic and trade relations related to the long-term interests of all countries, and therefore trade policy measures adopted by countries usually runs through the political and military considerations, and therefore the study of international trade policies and measures, not just from the economic point of view, and We should look at a problem from a political and economic perspective. International trade and the world economy on the country's participation in the development of trade has an important role, particularly in the following areas:

1, regulating supply and demand in the national market

States regulate the market supply and demand, exchanges always been an important feature of international trade. World production levels due to the impact of science and technology and the distribution of production factors and other factors, production capacity and market demand and supply situation there is a degree of difference. Both within countries exist products in short supply situation, and there are various forms of product surplus situation. And through international trade can not only increase the market supply shortage of domestic products to meet consumer demand, but also for the domestic markets of the surplus product provides a new way, to a certain extent, ease the contradiction between supply and demand in the market, thereby adjusting market supply and demand countries.

2, to promote the full use of production factors

In today's world, labor, capital, land, technology and other factors of production located in various countries are often uneven, some national labor surplus and capital shortage, some countries lack the capital and abundant land, vast land and some countries backward farming techniques. If there is no international trade, domestic production scale development of these countries and the social productive forces, which will be subject to a shortage of factors of production constraints, some factors of production will be idle or wasted, production potential can not be realized. Through international trade, these countries can take the international trade in services, capital transfers, land leasing, technology trade, etc., the factors of production of domestic surplus with other countries to exchange shortage of domestic factors of production, so that the shortage of factors of production constraints to ease or elimination of surplus factors of production can be fully utilized to expand the scale of production, and accelerate economic development.

3, comparative advantage, an important basis for improving the productivity of countries in international trade is comparative advantage and comparative advantage

The use of comparative advantage and comparative advantages of the international division of labor and international trade, commodity production can expand the narrow inferior commodity production and exports competitive products in exchange for their underdog goods from abroad, which can increase productivity at the same premise of social productivity performance elements, improve production efficiency, greater economic benefits.

4, improve production technology, optimize the domestic industrial structure

In today's world, the universal introduction of advanced science and technology and equipment through international trade, in order to increase domestic productivity levels, speed up economic development. Meanwhile, international trade, so that the domestic industrial structure gradually improve coordination and promote the coordinated development of the national economy.

5, increase revenue, improve the development of national welfare level of international trade, for a government to open up sources of revenue

Government can get a lot of revenue from the customs territory of the previous cargo tariffs, domestic taxes levied on the import and export goods, transit goods to provide a variety of services and so on. The federal government in the early days of the United States, tariff revenue has accounted for 90% of federal revenues. So far, foreign customs duties and taxes are still particularly important source of revenue for developing countries. International trade can also increase the level of welfare of citizens. It can be imported but domestic shortage is the urgent need for the goods or imported goods cheaper than domestic prices, better quality, more innovative style, features more prominent commodity to domestic consumers get more benefits. In addition, the expansion of international trade, especially in labor-intensive exports growth will provide more employment opportunities for domestic and indirectly promote national welfare.

6, strengthen national economic ties and promote economic development

In modern times, the world conduct extensive international trade activities, which not only developed a high level of productivity linked to each other, but also the low level of development of productive forces developing countries caught up in international economic life. Competitive activities of the international market, also contributed to the overall development of the world to further accelerate productivity. This will not only promote the further development of the economies of developed countries, but also to promote the economic development of the least developed countries and regions.

Innovative way of international trade [1]
Research on the status quo of international trade will lead to the development of international trade theory. When the capitalist mode of production began to sprout, the bourgeoisie in international trade, the role of increasing the time, we begin with the bourgeoisie first international trade theory - mercantilism. However, this international trade theory does not reveal the nature and significance of international trade, with the development of the capitalist mode of production, the bourgeoisie awareness of international trade continues to deepen, to Adam? Smith and David? Ricardo as the representative of the United Kingdom classical economics make more scientific explanation of the causes and significance of international trade production. They have put forward a theory of absolute advantage and comparative advantage theory that labor productivity in different countries can develop their absolute advantage or comparative advantage in international division of labor, specialized production of their absolute superiority relative advantages of the product, through international trade, countries You can make a profit. On this basis, other economists on international trade issues in the exchange rate, international trade expanded in-depth study of the distribution of benefits issues. Sweden Heckscher and Ohlin in the early twentieth century, based on the theory of Smith and Ricardo, factor endowments theory further proposed that the production cost differences between countries factor endowments differences caused by the generation of the cause of international trade . Smith and Ricardo and their theories have emphasized free trade will give the benefit of the participating countries in international trade, thus forming a free trade theory of international trade. Different international trade theory to guide the practice of foreign trade, will produce a wide range of specific trade policies and measures. Free trade theory suggests that it should try to eliminate obstacles to trade development measures, such as reductions in tariffs and non-tariff barriers and trade protection theory is that should be based on the needs of its industrial development, there is mining duties and other non-tariff measures to restrict certain products imports, encourage the export of certain products. Various policy measures impact on imports and exports is not the same, what kind of measures to adopt, or in combination of several measures to achieve target certain areas, we need to make a special research and analysis. Practice of modern international trade show, both on the international trade market there is competition, but also there is the use of different countries. So by different countries will sign various agreements, treaties or participate in certain international economic organizations to constrain their behavior and norms. These agreements, treaties and international economic organizations exactly how many Member States will bring concrete economic benefits or losses, usually requires researchers conducted a special analysis. The facts tell us that the international economic and trade relations related to the long-term interests of all countries, and therefore trade policy measures adopted by countries usually runs through the political and military considerations, and therefore the study of international trade policies and measures, not just from the economic point of view, and We should look at a problem from a political and economic perspective.

International Trade Organization in the form of a virtual enterprise innovation
Traditional organizational enterprises are faced with a great impact on e-commerce functions based organizations also received widespread attention, it has brought vitality. Virtual Enterprise is a typical representative of the network organizational structure. It there is no region, industry, business boundaries, all the resources without any constraint, links to all resources via electronic means, all its resources for its effective organizational entity used to play its biggest utility. Definition of virtual enterprise is vague, not a strict concept. It is the enterprise resource effective match different combinations. Determine the characteristics of virtual enterprise rigid structure of traditional enterprises are no longer adapted to the contrary, the opposite of the rigid organizational structure as a flexible network plays an important role in leading, flexible networking capabilities and the associated resources accordingly match, to achieve optimal allocation of resources.

Innovation --EcR flow of international trade patterns
The rapid development of the Internet to bring consumers a choice more and more, in the face of the great variety of goods, consumption of its self-consciousness gradually increased, new product requirements are rising, demand for personalized more prominent. In order to meet the rapidly changing needs of consumers, international trade flows derived a new distribution model, that effective consumer response (EficientConsumetResponse) ~ T referred ECR, unprecedented changes its appearance occurred and effective promotion. It's fast, good features to meet consumer demand. ECR mode to the traditional mode of foreign trade is a revolution, it has the following advantages: (1) pay attention to the introduction of new technologies and new methods. ECR international trade system is a revolution that leverages advanced information technology between manufacturers and sellers has set up a bridge that automatic ordering system (CAO). Application of the system from the fundamental solution to China's foreign trade ,, a lot of problems to deal with, especially new trade protectionism played a multiplier effect.

(2) establish a stable partnership. In traditional foreign trade commodity supply chain, each link of the chain are each isolated, without any closely related, and each time ordering randomness are difficult to grasp.

Channels of international trade an electronic innovation intermediaries
Electronic brokers characteristics are obvious: (1) a virtual exchange. Electronic brokers on this basis has been adjusted and innovation. Electronic broker as a transaction by mutual recognition of the media, it is positioned as the physical attributes - a place, the place not only have the function of reserve information, and the exchange places provide a wealth of information for producers to meet producers consumer information needs. Especially with information about the purchase. Thus was born the virtual switching operation, and bear shall bear the mission.

(2) provide information intermediary services. The service is a new thing, with the process of the information derived. A new thing, with the process of the information derived. A new thing, with the process of the information derived.
