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

山区是乡村传统文化、乡村风景、乡村休闲、乡村农业教育功能、自然资源和自然环境得以保存的重要地区。为了保持山区的可持续发展，增加农民的农业收入，促进山区农业和农村基础设施建设项目的发展是非常重要的。本研究是以促进山区农业和农村基础设施建设项目为目的的基础性研究，有以下三个目标：（1）讨论并阐明了山区区域农业整体经济价值的概念和测度;（2）讨论并明确了山区农业与农村基础设施开发项目整体经济价值的概念和测度;（3）对农业和农村基础设施建设项目费用负担制度进行了考察，本研究以福井县大野县南六郎和岐阜县希达县牛川为例进行了实证研究，并从公共经济学和地区会计学的角度进行了理论分析，得出了以下结论。(1)明确了农业和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方法。(2)建立了评价工程经济整体效果的居民问卷调查模型。(3)由于工程的影响，居民对生活环境和农业环境的评价很高。(4)项目投资效率（总效益/成本）在项目中非常高。

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.
