Concept and Measure of Economic Value of Effects of Agricultural and Rural Infrastructure Development Project in Mountainous Regions

山区是乡村和传统文化、乡村风景、乡村娱乐、农村和农业教育功能、自然资源和自然环境保护的重要地区。为了维持这些山区，保持农民的农业收入和促进那里的农业和农村基础设施发展项目对我们来说非常重要。本研究是推动山区农业及农村基础设施发展项目的基础性研究，主要有以下三个目标：(1)讨论和阐明山区区域农业整体经济价值的概念和测度；(2)讨论和明确山区农业农村基础设施建设项目整体经济价值的概念和测度；(3)审议农业农村基础设施建设项目费用负担制度。本研究以福井县大野市南黑市和岐阜县飞驒市新川市为个案进行实证研究，并从公共经济学和区域会计的角度进行理论研究。一些结论如下。(1)明确了农业农村基础设施建设项目（以下简称项目）整体效益经济评价的概念和测度。(2)建立了评价项目经济整体效果的居民问卷模型。(3)由于项目的影响，居民对生活环境和农业环境的重视程度都很高。(4)项目投资效率（总效益/成本）非常高。

Mountainous areas are very important as the areas where rural and traditional cultures, rural sceneries, rural recreatoins, educational functions of rural and agriculture, natural resources, and natural environments are conserved. For sustaining these mountainous areas, it is very important for us to keet up the agricultural income to the farmers and to promote the agricultural and rural infrastructure development projects there.This study is fundamental with the aim of promoting the agricultural and rural infrastructure development projects in the mountainous areas, and has the following three objectives : (1) to discuss and to elucidate the concept and the measure of whole economic value of the regional agriculture in the mountainous areas, (2) to discuss and to make the concept and the measure of whole economic value of the agricultural and rural infrastructure development projects in the mountainous areas clear, (3) to review the system of expense burden for the agricultural and rural infrastructure development project.This study was empirically with the case study of Minami-Rokuroshi in Ohno, Fukui Prefecture and Nyukawa, in Hida, Gifu Prefecture as well as thoretically from the viewpoints of public economics and regional accounting.Some of conclusions are as follows. (1) The concept and the measure of economic evaluation of whole effects of the agricultural and rural infrastructure development projects (we refere this as the projects, here) were made clear. (2) A model of questionnaire to inhabitants for evaluating economically whole effects of the projects was made. (3) As the effects of the projects, the inhabitants set a high value on the living environment as well as the agricultural environment. (4) Efficiency of project investment (total benef/cost) is very high in the projects.
