Sharing goods and services has been promoted as fostering more sustainable consumption. In this paper, we explore sharing in a middle-class neighbourhood in a Norwegian city. We ask what influences and frames neighbours’ current sharing practices, contending that Polanyi’s notions of exchange systems, specifically reciprocity and redistribution, yield valuable insights for our study. We show that reciprocal and redistributive sharing may reinforce each other by increasing the frequency of sharing and the variety of items shared. Furthermore, redistributive sharing systems may foster close relations and interpersonal trust, which are prerequisites for reciprocal sharing. Hence, if the goal is to increase the rate of sharing of goods and services in neighbourhoods like that studied here, two initiatives can be valid. First, items with the right affordances can be redistributed by existing institutions; second, reciprocity can be encouraged by organising more opportunities for resident interaction.

促进商品和服务共享以促进更可持续的消费。在本文中，我们探讨了在挪威城市中产阶级社区中的共享。我们询问什么会影响和构架邻居当前的共享做法，并认为波兰尼的交换系统概念（特别是互惠和再分配）会为我们的研究提供有价值的见解。我们表明，互惠和重新分配共享可以通过增加共享的频率和共享的项目的种类来相互加强。此外，再分配共享系统可以促进紧密的关系和人际信任，这是相互共享的前提。因此，如果目标是像在此研究的那样，提高附近社区商品和服务的共享率，则两项举措都是有效的。第一，可以由现有机构重新分配具有适当能力的物品；其次，可以通过组织更多的居民互动机会来鼓励互惠。
