茶叶,由于产地的局限性和消费区域的广泛性,自古以来,很早就作为商品生产,西汉王褒《僮约》的记载,说明西汉末,茶叶就有买有卖,并已建立市场,但由于小农经济的分散经营,产量否高,产地不广——局限于四川西南部,买卖还不普遍,大都作为贵重物品,为上层统治阶级享用。 Due to the limitations of the place of production and the extensiveness of the consumption area, tea has long been used as a commodity production since ancient times. The records of Wang Tong’s “Tongyue” in the Western Han Dynasty show that at the end of the Western Han Dynasty, tea was bought and sold and the market was established. However, due to the fragmentation of small-scale peasant economy, the output is not high and the production area is not wide-limited to the southwest of Sichuan. Buying and selling is not yet widespread. Most are valuable items for the upper ruling class to enjoy.
