Open-air marketplaces are vital to food security, livelihoods, and the national economy in Papua New Guinea (PNG). Over the past 60 years, rapid growth of urban populations, changes in global commodity prices, and the decline in value of the PNG currency have stimulated demand for domestic fresh food. Selling fresh food in marketplaces has also become an attractive way to earn money for rural producers, whose returns on labour on their export crops have declined, and for urban residents struggling to make a living. This in turn has led to significant changes in PNGʼs marketplaces: spatial and temporal changes, changes in what is bought and sold, changes in who is selling, and changes in how food is transacted. In this paper, we bring together research on PNGʼs marketplaces from between 1961 and 2022 to document these changes and their causes, alongside important continuities, and to examine the implications and substantial gaps in our knowledge.

市场更新：巴布亚新几内亚新鲜食品市场六十年的变化

露天市场对巴布亚新几内亚 (PNG) 的粮食安全、生计和国民经济至关重要。60年来，城市人口的快速增长、全球商品价格的变化、巴布亚新几内亚货币的贬值，刺激了国内生鲜食品的需求。对于农村生产者来说，在市场上出售新鲜食品也成为一种很有吸引力的赚钱方式，他们的出口作物的劳动力回报率已经下降，对于努力谋生的城市居民来说也是如此。这反过来又导致巴布亚新几内亚市场发生重大变化：空间和时间的变化、买卖物品的变化、销售人员的变化以及食品交易方式的变化。在本文中，我们汇集了 1961 年至 2022 年间对巴布亚新几内亚市场的研究，以记录这些变化及其原因，
