Import Rate and Export Rate 怎樣影響GDP?

最簡單一個appropch

Gross Domestic Product (GDP) is an aggregate measure of the market value of all final goods and services produced by the resident producing unit of a country in a specified period，usually one year
resident producing unit=常駐生產單位
常駐生產單位指某人會以香港為佢自己ge經濟利益中心，佢所生產ge物品先叫香港生產的
GDP意思係計算香港一年內ge總生產量

Import of foreign product which is not prdouced by HK，so how can we say it will increase GDPof HK
The increase in import the decrease in HK GDP
It is a fallacy and silly to say import can improve HK GDP ，when someone say that it means he does not know what the maening of GDP
I can't find any Economist have even been said about that import capital , and resources in order to develop the economic and then export to earn profit.

You can find the famous economist Keynesian who is the first one to construct the modern Marcoeconomic

On the other hand，the increase in export can increase HK GDP
As the product are produced by HK whatever the good are consumed by the HK resident or export to an other country consumed by foreigner ，it should calculate in HK GDP

The definition of GDP you can find it from Census and Statistics Department
