【摘要】The phrase ‘executive governance’ refers to the merger of two discrete bodies of work, the study of executive government in political science and the study of governance in public administration. We focus on their intersection; on common ground and shared puzzles. We start with a brief account of the several approaches to executive studies in political science, and of the various waves in the study of governance. We cover the core executives of Westminster and Western Europe parliamentary polities. After this conspectus of the literature, we devote most of our attention to the shared puzzles where executive studies and governance intersect. We focus on four puzzles: predominant or collaborative leadership; central capability or implementation; formal or informal coordination; and political accountability or webs of accountabilities. We conclude with some suggestions about the directions for future research under the headings of: the interpretive turn, court politics, and presidential studies.
