In economics, factors of production are the inputs to the production process. Factors of production may also refer specifically to the primary factors , which are STOCKS INCLUDING land, labor (the ability to work), and capital goods applied to production.

In markets, entrepreneurs combine the other factors of production, land, labor, and capital, in order to make a profit. Often these entrepreneurs are seen as innovators, developing new ways to produce and new products. In a planned economy, central planners DECIDE how land, labor, and capital should be used to provide for maximum benefit for all citizens.
