貿易是指什麼工作 ?

貿易（英文係trade）是自願的貨品或服務交換。貿易也被稱為商業。貿易是在一個巿場裏面進行的。最原始的貿易形式是以物易物，即直接交換貨品或服務。現代的貿易則普遍以一種媒介作討價還價，如金錢。金錢的出現(以及後來的信用證、鈔票以及非實體金錢)大大簡化和促進了貿易。兩個貿易者之間的貿易稱為雙邊貿易，多於兩個貿易者的則稱為多邊貿易。 貿易出現的原因眾多。由於勞動力的專門化，個體只會從事一個小範疇的工作，所以他們必須以貿易來獲取生活的日用品。兩個地區之間的貿易往往是因為一地在生產某產品上有相對優勢，如有較佳的技術、較易獲取原材料等。

Trade is the voluntary exchange of goods, services, or both. Trade is also called commerce. A mechanism that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and services. Modern traders instead generally negotiate through a medium of exchange, such as money. As a result, buying can be separated from selling, or earning. The invention of money (and later credit, paper money and non-physical money) greatly simplified and promoted trade. Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade.
Trade exists for many reasons. Due to specialisation and division of labor, most people concentrate on a small aspect of production, trading for other products. Trade exists between regions because different regions have a comparative advantage in the production of some tradable commodity, or because different regions' size allows for the benefits of mass production. As such, trade at market prices between locations benefits both locations.
Trading can also refer to the action performed by traders and other market agents in the financial markets.

貿易通常指進口及出口貨物賣買的工作。

例如一家公司從外國採購一些貨品在本港出售, 這叫貿易。

又例如另一家公司向國內廠家購入貨品以轉口到海外公司，這也叫貿易。

貿易公司是將來自第三手製作的商品,經由進步的國家像是歐美日本等國幫忙著設計與商品化流程、然後銷售出口的公司。 ...
