土地改良の経済効果に関するパネルデータ分析

AI解説:
土地改良は、農業の生産効率を向上させる直接的な経済効果のみならず、高収益作物の導入や生産構造の改善を通じた生産コストの低減や収益性の向上といった間接的な経済効果も持っています。この研究では、新潟県の市町村別データを使用し、土地改良の経済効果をパネルデータ分析によって計測することを目的としています。特に、地域性と構造変化を考慮した詳細な分析を行い、土地改良の真の経済効果を明らかにすることを目指しています。

著者による要約:
Land improvement has both direct and indirect economic effects on agricultural production. Besides of its direct economic effects on agricultural production by improving efficiency of agricultural production, the indirect economic effects of land improvement can also be obtained through reduction of production costs such as the improvement of production structure or improvement in profitability such as introducing high profit crops. Such economic effects (both direct and indirect) of land improvement will be finally reflected into land profitability. Therefore, it is considered that we can estimate economic effects of land improvement by measuring the relation of the land capital stock and land profitability in agricultural sector. However, economic effects of land improvement are usually influenced by regional difference and structural change in agriculture. Thus, in order to make an accurate estimation, we apply the panel data analysis to the data at 2 points of time of each city, town and village of Niigata prefecture instead of using cross-section data or time series data as a usual way of estimation, and clarify the economic effects of land improvement in this area.
