Abstract

過疎地域の交通支援政策に関する意識調査において,質問項目の違いが回答結果に及ぼす影響を明らかにする.具体的には,回答者の経験や認知に関する設問により,1)政策の理解が高まる,2)WTPの期待値が上昇する,という2点の研究仮説を検証する.前者については,政策への認知や経験の喚起,政策の理解などを潜在変数として共分散構造モデルを推定し,その因果構造を明らかにする.後者については,WTPモデルを構築し,4種類の調査票ごとにWTP分布を推定した上で,それらの比較により,質問項目の違いがWTPに及ぼす影響を定量的に把握する.また,回答者属性がWTPに直接的に及ぼす影響と,回答者属性が経験や認知を喚起する質問項目への回答を介してWTPに及ぼす間接的な影響を識別するために,傾向スコア法を用いる.

The rural communities in the middle mountainous areas and islands or peninsula suffer from low birthrate, aging and depopulation. In order to maintain the infrastructure in these areas, the income transfer from the other region is necessary. This study analyzes the influence of combination of survey items on investments for the transportation policy in the rural area. Following two hypotheses are tested in this study are as follows: 1) understandings of the policy increase, 2) the WTP increases, when the experience and the cognition of respondents about the transportation policy in the rural area are evoked by survey items. In order to specify the survey item effect, specify the survey item effect, the propensity score is applied in the WTP model. Statistical analysis proved the above two hypotheses. We can conclude that the survey items can be utilized as a communication tool to the respondents.
