Urban markets are a complex and unique ecosocioeconomic phenomenon, constituting micro-societies with their own social, political, and economic rationales which provide alternatives to the prevailing logic. This article analyzes the farmers market in the Amazonian city of Castanhal, Pará, Brazil from an ecosocioeconomic point of view, and is based on documentary analysis and oral statements taken from vendors. The findings show that for over three decades, this urban farmers market has functioned as a micro-society based on the emerging rationalities which result from everyday internal and external relationships; the market is a significant political and social actor within the network of urban governance and the local rural production chain. The vendors state that the market works in concert with the rules of local government are economically self-sufficient, have operational autonomy and socially constructed legitimacy, and that ecosocioeconomic relationships emerge from satisfiers which are located between the needs of work and leisure. In conclusion, this urban farmers market is socially and economically important for vendors, producers, and local residents, and its operation is linked to environmental sustainability criteria based on appropriate technologies and local knowledge.

城市市场是一种复杂而独特的生态社会经济现象，由具有自身社会，政治和经济原理的微观社会构成，这些社会为流行的逻辑提供了替代方案。本文从生态社会经济的角度分析了巴西帕拉亚马逊河市Castanhal的农贸市场，并基于文献分析和卖方的口头陈述。研究结果表明，在过去的三十多年中，这个城市农民市场一直是一个微型社会，其基础是日常内部和外部关系所产生的新兴理性。市场是城市治理和当地农村生产链网络中的重要政治和社会参与者。供应商指出，市场与地方政府的规则相一致，在经济上是自给自足的，具有经营自主权和社会建构的合法性，而生态社会经济关系则来自满足工作和休闲需求的满足者。总之，这个城市农民市场对供应商，生产者和当地居民具有社会和经济意义，其运作与基于适当技术和当地知识的环境可持续性标准相关。
