July-September is the off-season, mainly because many companies in western countries will have holidays or take turns to release them. But it also depends on the product type. Pure consumer products are more obvious, but if they are only large items or unconventional items, this time will not have much impact on them.
Foreign trade, also known as "foreign trade" or "import and export trade" or "foreign trade" for short, refers to the exchange of goods, services and technologies between one country (region) and another.
This trade includes two parts: import and export. For countries (regions) that import goods or services, it is import; For countries (regions) that transport goods or services, it is export.
This began to emerge and develop in slave society and feudal society, and it developed more rapidly in capitalist society. Its nature and function are determined by different social systems.
Trade dependence is also called "foreign trade dependence" and "foreign trade coefficient". A country's trade dependence is generally expressed by the proportion of foreign trade import and export value to gross national product or gross domestic product.
That is, trade dependence = total foreign trade/gross national product. The change of proportion means the change of the position of foreign trade in the national economy. Trade dependence can also be expressed by the proportion of total trade to national income.
Dependence on trade = total trade/gross national income. Dependence on foreign trade can be divided into export dependence and import dependence.
Export dependence = total exports/gross national product; Dependence on imports = total imports/gross national product.
