Final answer:
The full value of the automobiles produced by General Motors in China is included in China's GDP, as GDP accounts for production within a country's borders. However, the value would be included in the US GNP since General Motors is a US company.
Step-by-step explanation:
If General Motors, a US corporation, produces automobiles entirely in China and sells them in South Korea, the full value of the automobiles produced is included in China GDP. This is because GDP (Gross Domestic Product) measures the market value of all final goods and services produced within a country's borders in a given time period.
Since the production occurs within China, regardless of where the cars are sold, the value is added to China's GDP. China's GDP reflects the output produced within its territory, and it does not consider the nationality of the producer. Hence, it includes the cars manufactured by General Motors in China.
Gross National Product (GNP), on the other hand, measures the market value of all final goods and services produced by residents of a country, within or outside the country's territory. Since General Motors is a U.S. corporation, the value of the automobile's production would be included in the US GNP rather than the GNP of China.
