<p>In order to develop a new FAME production scheme that can reduce price volatility risks in the production of vegetable oils and fats, FAMEs, valuable resources, and the like, a FAME production method and a FAME production system related thereto are provided, whereby vegetable oil obtained from raw oil in a pressure extraction step (A1) and byproduct containing fatty acids obtained in a refinement step (A2) as a byproduct of said vegetable oil are mixed (symbol 1) in a vegetable oil and fat production system (A), and FAMEs are produced in a reaction tank according to a catalyst-free method in a FAME production section (B). If there is a desire to raise the level of production of vegetable oils and fats on the basis of supply and demand balance and price volatility, for example, the quantity of vegetable oil to be provided for vegetable oil and fat production is increased, the quantity of vegetable oil to be provided for FAME production is reduced, and the percentage of byproduct containing fatty acids
