The commercial revolution is manifested in the expansion of the world market, the increase of the types of commodities in circulation and the transfer of trade centers. After the opening of the new route, the previously isolated areas in the world communicate with each other, which can be said to be the first step to strengthen the ties between different regions in the world. Therefore, the trade between Europe and Africa, America and Asia is developing day by day, and the world market is expanding. The expansion of the world market also means that more and more new products appear in the markets of various countries. Especially, many agricultural products from America spread to Eurasia. With the opening of new air routes, the center of world trade has shifted from the Mediterranean coast to the Atlantic coast. Commercial cities such as Venice and Genoa in Italy declined, and cities such as Lisbon and Seville took their place. Ports on both sides of the North Sea came from behind and occupied the central position of maritime trade more and more.

2. Another consequence of the opening of the new route is the price revolution.

The performance of the price revolution is that American silver flowed into Spain, then from Spain into Genoa, and finally into the Ottoman Empire. Silver flows eastward, and the prices in the areas it passes through rise rapidly, and the currency depreciates. The sharp rise in prices has had a far-reaching impact on the social development of European countries. The price revolution has promoted the changes of class relations in European countries. First, feudal landlords who collected fixed-currency land rent in the traditional way, their real income decreased due to currency depreciation, and they fell into poverty and bankruptcy. Second, handicraft workshop owners, capitalist farmers and new noble have made huge profits. Not only can they buy labor more cheaply, but they also have a lot of products to sell. It can be seen that the price revolution has effectively accelerated the decline of feudal system and the development of capitalism. However, the price revolution played a different role in Spain. /kloc-In the first half of the 6th century, the Habsburg dynasty of Spain pursued the policy of dominating Europe and used huge wealth for military and political activities. In order to pursue a luxurious life, Spanish nobles spent a lot of money, which led to the situation that the gold and silver shipped back from American colonies were quickly transferred to suppliers and creditors in other countries. The colonial activities carried out by Spain can only be used as a wedding dress for others to a great extent. The wealth plundered from the colonies did not turn into industrial capital, but flowed into Britain, France and other countries and turned into capital.

3. The opening of the new air route proves the theory of the earth circle.

4. The opening of the new air route has prepared the conditions for the formation of the world market.

As a result, the world began to break the isolated and closed state in the past, strengthen ties, and gradually began a new process of integration.

5. Early colonial activities and plunder also began with the opening of new air routes.

The colonial empires led by Spain and Portugal carried out early colonial expansion in Asia, Africa and Latin America, and the Western colonial era began.

The new sea route refers to the sea route to India, America and other parts of the world that western European countries want to explore at the turn of the century from 15 to 16.

The opening of the new route is no accident. It has profound economic and social roots, as well as some religious and ideological roots.
