Outline of Final Research Achievements |
This study investigates the effects of inter-municipal cooperation in municipal solid waste disposal on waste disposal costs. Using a dataset of disposal costs from 2006 to 2015 for all municipalities in Japan, we investigate whether inter-municipal cooperation in the disposal process induces economies of scale and scope. We find that municipalities with inter-municipal cooperation have lower disposal costs, and the effect is remarkable in municipalities with smaller waste emission scale. Our results also show that cooperation in multiple disposal processes is more effective for cost reduction, which suggests the presence of scope economies. These results indicate that economies of scale and scope play a significant role in the cost efficiency of municipal solid waste disposal.

Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義および社会的意義は、これまでに扱われてこなかった処理過程ごとの費用を把握することによって、国内外を含めて現状では十分に明らかになっていない広域化における費用効率性について処理過程別に明示し、広域化が処理費用全体に与える影響について網羅的に明らかにできたことである。さらにこれらの研究成果は、広域処理政策だけではなく、リサイクル政策や有料化政策の費用効率性など、あらゆる廃棄物処理政策の費用便益分析への応用を可能にする。したがって本研究の成果は、人口減少による新たな経済・社会情勢に対して、効果的かつ効率的な公共政策の成立に向けた新たな知見を与える。
