Tsars, leadership and innovation in the public sector
研究了英国政府中“沙皇”角色的定义、作用及其作为官僚企业家的程度，聚焦卫生部案例，分析其如何利用资源影响政策结果，填补新型治理的空白。
Tsars are increasingly being used in government to coordinate policy, to deal with complex problems and to implement government goals. However, there is almost no extant literature on the role of tsars who occupy a curious position in Britain's constitutional framework. The aim of this article is to examine the role and impact of tsars. The article attempts to define tsars and examines the extent to which they are bureaucratic entrepreneurs. Focusing on tsars in the Department of Health, where they have been most systematically used, the article examines the resources that they have to shape policy outcomes. The article highlights the way in which leadership is being used to fill in the holes created by new forms of governance.
