Social network analysis on self-organizing process of local politics

本研究的目的是。用社会网络分析法，特别是认知社会网络分析法分析社区权力结构的自组织政治过程。我特别将社会网络感知的准确性作为分析社区权力结构的关键社会变量。作为本次研究的对象，我选取了山梨县益豪镇地区的社区权力结构，特别是阻碍该地区社会运动的高尔夫球场建设。我对该地区政治企业家的社会关系进行了问卷调查，并对他们进行了访谈。通过这项研究，我发现了以下结果和事实。非常密集的社会交流和对他们的认知有数据支持。但共识型社会网络不同于局部聚合型社会网络，后者是由被调查者的社会关系反应聚合而成的社会网络。我还研究了网络感知的“准确性”概念。网络感知的准确性通常被定义为受访者的网络感知与局部聚合结构网络的一致，我研究了另一个“准确性”概念：即受访者的感知与共识社会网络的一致。我发现LAS（局部聚合结构）的“准确性”与网络的中心性相关，但共识结构的“准确性”与之无关。我的结论是，共识结构的知识没有信息价值，正如许多人所共享的那样，而潜在结构的知识是有用的。阻碍该地区社会运动的高尔夫球场建设在明显交往阶段进行得不好，但在潜在交往阶段取得了成功。该运动的潜在支持者分布在广泛的社会领域，这一事实得到了网络分析结果的支持。我发现一些运动的领导者在网络感知方面很出色。

The purpose of this research is. analyzing self-organizing political process of community power structure with social network analysis, especially with cognitive social network analysis. I especially take up the accuracy in social network perception as key social variable of analyzing the community power structure.As object of this research, I took up the community power structure of Masuho Town area in Yamanashi Prefecture, especially the golf course construction blocking social movement in the area. I carried out a questionnaire investigation on the social relationship between political entrepreneurs in that area and interviews on them.I found following results and facts through this research. Very dense social communications and cognition of them were supported with data. But consensus social network of those is differ from social network of locally aggregated structure, which is social network aggregated with social relationship response of respondents.I also examined the concept of "accuracy" of network perception. Ordinary concept, of accuracy of network perception is defined as accordance of respondents' network perception to locally aggregated structure network, and I examine the other "accuracy" concept : that is 'accordance of respondents' perception to consensus social network. I found "accuracy" to LAS (locally aggregated structure) has correlation to centrality of network, but, "accuracy" to consensus structure has no correlation to it. I concluded that, knowledge of consensus structure has no informational value, as is shared by many people, and knowledge of latent structure is helpful.The golf course construction blocking social movement of that area did not carry well in apparent communication phase, but it succeeded in latent communication phase. The latent support for the movement was spread in wide social area, the fact was supported by the network analysis result. And I found some leaders of the movement have excellence in network perception.
