The objective of this article is to explore how the mobility power of nurses (the ability to move between employers or leave the labor market) contributes to changing relations between health institutions and temporary work agencies in the Norwegian welfare state. Based on case study as the research strategy, the article contributes to the political economy of labor relations approach and the debate over the role ofTWAs and temporary nursing in the health sector.The mobility power of Swedish nurses who shift from agency nursing to direct temporary nursing in health insti- tutions (bank nursing) partly explains the constrained growth of agency nursing in the Norwegianhospital sector. However, contracting flows of Swedish nurses to Norway since 2015 challengeinternal labor hire and could make health institutions more agency-dependent in future.The dataemployed are semi-structured interviews, official statistics, reports, and news clippings.

卫生机构，临时工作机构和护士的流动能力

本文的目的是探讨护士的流动能力（在雇主之间移动或离开劳动力市场的能力）如何有助于改变挪威福利国家中医疗机构与临时工作机构之间的关系。基于案例研究作为研究策略，本文为劳动关系方法的政治经济学以及关于TWAs和临时护理在卫生部门中的作用的辩论做出了贡献。瑞典护士的流动能力从代理护理转向直接临时护理卫生机构（银行护理）的研究部分解释了挪威医院部门代理护理的增长受限。但是，自2015年以来瑞典护士流向挪威的合同流动挑战了内部劳力的聘用，并可能使卫生机构今后更加依赖机构。
