What effect does an increase in investment spending have on a country's GDP?

When a country increases its investment spending, it usually leads to a rise in its Gross Domestic Product (GDP). Investment spending means that businesses are buying new equipment or building new facilities, which creates jobs and helps the economy grow. For example, if a car company decides to build a new factory, it will need workers to construct it, and later, to produce cars. This increase in jobs means more people have income to spend, which can boost other areas of the economy as well. Overall, more investment spending helps to create a cycle of growth that can raise the country's GDP.
