联合国粮农组织（Food and Agriculture Organization of the United Nations（FAO））给出的定义：

“The farm gate prices are in principal the prices received by farmers for their produce at the location of farm. Thus the costs of transporting from the farm gate to the nearest market or first point of sale and market charges (if any) for selling the produce are, by definition, not included in the farm gate prices. Thus the prices collected from such markets may be adjusted for these costs to arrive at farm gate prices. In a number of countries, some commodities are sold at farm-gate, while others are sold at markets or delivered to purchasers' premises. Sometimes the recorded off-farm prices are adjusted to the farm-gate equivalent by allowing transport costs but in many cases no adjustment is made. In many developing countries, agricultural marketing is not well organised and farmers use the entire range of distributive channels: farm-gate, local village markets, wholesale and retail markets and sales of export crops to marketing boards. In order to approximate farm gate prices information on the marketing channels used and quantity sold for different crops and other products is required. Average prices should then be worked out using the output disposed of through various channels as weights. Thus the prices that producers receive when they sell their output should be used, as the attempt to separate the trade and transport margins is usually neither practical nor useful.”

Farm Gate Price可翻译为“农场交货价格”。据百度百科解释，农场交货价格是指以卖方按照合同规定的日期、地点（通常指农场）提交货物，并负担货物交由买方接收前为止的一切费用和风险为条件的价格。一般在国内贸易和陆地接壤国之间的贸易中应用。在国际贸易中，采用农场交货价格时，卖方须按照合同规定将货物备妥，书面通知买方提货，并协助买方在出口国取得必要的货物运输等有关凭证，负担农场交货并由买方接收前的一切费用和风险。货物交由买方处置后，卖方即可按合同规定收取货款。
