《宋史·列传·卷八十六》
均输法，是把发运的职能改为均输，朝廷给予钱币和米粮，凡是上供朝廷的物品，都必须离开价钱高的地区而在价钱便宜的地区购买，以路程近的地区代替路程远的地区，预先报告京城仓库需要购买的物品，以便能在价钱便宜时购买贮存。
均输法者，以发运之职改为均输，假以钱货，凡上供之物，皆得徙贵就贱，用近易远，预知在京仓库所当办者，得以便宜蓄买。
The Grain Transportation Policy changed the previous practice of shipping grain to the central government and established a new grain transportation system. The central government provided money and grain. All the commodities to be submitted to the government had to be purchased from areas with low prices instead of areas with high prices. And areas close to the transportation routes were used to replace areas far from the routes. In addition, the storage requirements of the capital city were reported to the government in advance so that the commodities could be purchased and stored when prices were low.
