First of all, the opening of new air routes has caused a "commercial revolution"; Its performance is the expansion of the world market, the increase of the types of commodities in circulation and the transfer of trade centers. The opening of the new route enables all regions in the world to communicate with each other, and the trade between Europe and Africa, America and Asia is developing day by day. In addition, with the opening of new 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 Lisbon and Seville took their place. There are more and more ports on both sides of the North Sea.

Secondly, the opening of the new route has caused a "price revolution"; The performance of the price revolution is that American silver flowed into Spain in large quantities, then into Genoa from Spain and finally into the Ottoman Empire. Silver flows eastward, and the prices in the passing areas rise rapidly and the currency depreciates. 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.

Third, the opening of the new air route has prepared conditions for the world market, and the world has begun to break the previous isolated and closed state, strengthen ties, and gradually began a new integration process.

Third, the opening of the new sea route marks the beginning of European colonial activities and plunder: the colonial empires led by Spain and Portugal carried out early colonial expansion on Asian, African and Latin American countries, and the western colonial era began.

Finally, the opening of new shipping routes promoted the development of commodity economy, feudal system declined with the opening of new shipping routes, and capitalism also accelerated its rise, which jointly promoted the development of commodity economy.
