Investopedia states that
Gross domestic product (GDP) is the total monetary or market value of all the finished goods and services produced within a country's borders in a specific time period.
But how does GDP be calculated? Some articles explained that GDP is being calculated and measured:The monetary value of final goods and services
. I understand that, but won't the value of the product be double - calculated ? What is actually the final (for the example below, for both the manufacturer and shipping company, the product/shipping service could all be considered as final
For example, I buy a Mac book. The Mac book is being produced in China and Apple company pay manufacturer a certain amount of money for manufacture that. Then, the product is shipped from China to other countries to sell. And I finally pay a larger amount of money to get the Mac from apple.
I just wonder will only the money I paid (the final goods) be contributed to GDP or the money apple pay to manufacture be also counted and shipping price be counted as well?
Could anyone explain me how it being measured?
Thanks for any responds
*I checked these two questions: What is the Gross Domestic Product (GDP)? and What is the Gross Domestic Product (GDP)?, but doesn't solve my confusion.
