What effect does an increase in investment spending generally have on GDP?

When investment spending increases, it usually leads to a rise in GDP, which stands for Gross Domestic Product. GDP measures the total value of all goods and services produced in a country. When businesses invest more money in things like new buildings, machinery, or technology, they are creating jobs and increasing production. For example, if a company builds a new factory, it not only employs workers but also contributes to the economy by producing more products. This overall growth in production and employment helps boost GDP, showing that more money is flowing through the economy.
