Swedish election study 1968

The 1968 election study is almost twice as big as the earlier election studies, largely because of the goal of the survey, which was to cover the system of representation. A separate study, addressed to the Members of Parliament, included similar questions put in this study of the electorate. In this way a comparison of the opinions of the electorate and the opinions of the MP´s is possible. Except the questions repeated in all election studies, this study includes questions on employment, public representation on bank boards, agricultural policy, income tax, privately-owned TV-companies, religion, aid to developing countries, defence expenditures, and the Common Market. There are also a number of questions about how different groups are treated by the authorities. It also includes questions about the respondent´s sympathies for different groups in society. This study also introduces the left-right scale, a ten degree scale on which the respondent positions the political parties according to the respondent´s opinion of the party as a left-wing, centre or right-wing party. The 1968 study is the second stage in the 1964-1968-1970 panel study.

Purpose:

Explain why people vote as they do and why an election ends in a particular way. Track and follow trends in the Swedish electoral democracy and make comparisons with other countries.

1968年选举研究的样本规模几乎是此前各届选举研究的两倍，这主要缘于本次调研的核心目标：覆盖代议体系（system of representation）。另有一项针对议员（Members of Parliament）的独立研究，其问卷设置与本次选民调研的题目高度相似，借此可实现选民与议员双方观点的对比分析。
除所有选举研究均涵盖的常规问题外，本次调研还涉及就业、银行董事会公共代表席位、农业政策、所得税、私营电视台、宗教信仰、对发展中国家援助、国防开支以及欧洲共同市场（Common Market）等议题。此外，调研设置了多道关于不同群体受当局对待状况的问题，另有部分题目用于了解受访者对社会不同群体的态度倾向。本次调研首次引入左右翼立场量表（left-right scale）：该量表共设10个等级，受访者可根据自身对政党的认知，将各政党置于左翼、中间派或右翼的对应位置。1968年的本次研究是1964-1968-1970追踪面板研究（panel study）的第二阶段。

调研目标：
阐释选民的投票动机及选举结果的形成逻辑；追踪瑞典选举民主的发展趋势，并与其他国家开展对比研究。
