Collaborative Research on Environment, Performance, and Leadership on Party Change

这项合作研究(与哈梅尔9112491)调查了政党变化的动态。它审查了在目标、议题立场、活动和缔约方组织方面产生变化的机制。将收集1950-1990年期间四个国家19个政党的时间序列数据。这些数据将被用来评估政党更迭的性质和程度，并从环境变化、政党在选举和政府中的表现以及领导决策方面解释这些变化。虽然这项研究侧重于个别政党，但对于理解政党制度的变化也将是重要的。要了解更大系统中的变化，就必须了解各个方面。此外，这两种类型的变化在理论上都是理解政府动态的核心。当这项密集的数据研究完成后，将增加我们对政党变化动态的理解。此外，收集的数据将对其他对政党感兴趣的学者具有持久的价值。

This collaborative research (with Harmel 9112491) investigates the dynamics of political party change. It examines the mechanisms that produce changes in goals, issue positions, activities, and organization of parties. Time-series data will be collected on 19 political parties in four countries for the period 1950-1990. These data will be used both to assess the nature and extent of party change and to explain those changes in terms of environmental changes, the parties' performance in elections and in government, and leadership decisions. Although focused on individual parties, this research also will be important for understanding change in party systems. An understanding of individual parties is necessary to understand changes in larger systems. Moreover, both types of change are central theoretically to understanding the dynamic of government. When completed this data intensive research will increase our understanding of the dynamics of political party change. Moreover, the data collected will be of lasting value to other scholars interested in political parties.
