Nation-wide Longitudinal Survey Study on Voting Behavior in the Early 21st Century

日本选举研究III （JES3）项目涵盖2001年至2005年的日本全国选举。这是对日本国民进行的9次抽样调查，将小泉纯一郎内阁时期的4次全国选举延长；2001年和2004年的参议院选举以及2003年和2005年的众议院选举。这些数据是为了在每次选举前后进行面对面访谈而设计的（除了两次例外：2001年选举后的电话调查和2003年全国地方选举的邮件调查）。在7次面对面访谈中，537名受访者在所有这些场合都接受了访谈。受访6次及以上的N为1064，受访5次及以上的N为1352。就每次选举而言，在调查前后均接受访问的受访者N为；2001年，N=1253；2003年，N=1769；2004年，N=1810；2005年，N=1428。随着政治参与和政治态度越来越难以被社会人口因素预测，更多微观层面的心理因素变得越来越重要。与此同时，选民对政治制度、政党制度、媒体和经济形势变化的反应仍然是重要问题。考虑到这些，主要研究课题如下：1。选举制度改革效果的原因分析从政治参与的角度分析日本志愿者组织与社会传播的特点。3 .理性选择在选举参与与投票行为中的启示研究。衡量政府经济成就对投票行为的影响。政党认知动态的社会心理学模型研究。社会共享信息形成（民意基础）对投票行为的影响分析。我们的最终结果将以英文公布。2004年数据的一部分也作为CSES2项目的一部分发布了（http://www.cses.org/）。

The Japanese Election Study III (JES3) project covers Japanese National Elections from 2001 to 2005. It is a panel survey with 9 waves for Japanese national sample, which extends the four major national elections under the Koizumi's Cabinet; the 2001 and 2004 House of Councilors Elections and 2003 and 2005 House of Representatives Elections. The data was designed to make face-to-face interviews before and after each of the elections (with two exceptions; the 2001 post-election telephone survey, and the 2003 General Local Election mail survey). Out of the 7 face-to-face interviews, 537 respondents were interviewed in all of these occasions. N for 6 times or more interviewed was 1064, and 5 times or more was 1352.As for each Election N of the respondents who were interviewed both of the pre and post survey was; for 2001, N=1253; for 2003, N=1769; for 2004, N=1810; for 2005, N=1428.As political engagement and attitudes becoming less predictable by social demographic factors, more micro-level psychological factors are gaining importance. Meanwhile, voters' response toward the changing situations of political system, party system, media and economy remains important issues. Considering these, the main research topics were as follows;1. Causal analyses on the effects of reform of election system.2. Analyses of Japanese characteristics in volunteer organizations and social communication in terms of political engagement.3. Investigation of revelations of rational choice in election participation and voting behavior.4. Measuring effects of governmental economic achievements toward voting behavior.5. Investigating social psychological models of the dynamics in party cognition.6. Analyses of the effects of socially shared information formation (the foundation of public opinions) toward voting behavior.Our final results will be released in English. Also a part of the 2004 data was released as a part of CSES2 project (http://www.cses.org/).
