    This study examines the characteristics and problems of self-accounting bookkeeping in four steps. First, it examines prior research. Second, it considers the requirements of an “orderly bookkeeping system.” Third, it considers this system for single-entry, double-entry, and self-accounting styles. Finally, the study clarifies the characteristics and problems of self-accounting bookkeeping. The results were as follows: (1) self-accounting bookkeeping requires an “orderly bookkeeping system.” (2) Double-entry bookkeeping is not an “orderly bookkeeping system.” (3) Single-entry bookkeeping cannot satisfy the requirements of an “orderly bookkeeping system”. (4) Self-accounting bookkeeping has a self-auditing function, which is subject to farm management.

    日本の家計では高度経済成長期に畜産物の家計消費量が増加し,この時期の20年間で消費量は約5倍となった.この要因として考えられるのは,家計所得の増加による増加分が半分の約2.5倍,残りの半分は,価格の低下,嗜好の亢進,官製食育によるものである.その後,70年代後半に日本経済が低成長に転換すると,畜産物の家計需要量も停滞傾向に転じた.畜産物の中での主要品目である牛肉について近年の国内需要についてみると,特徴的なのは,2003年12月に米国で発生したBSEの影響で豪州産が米国産に代替したが,数量ベースで輸入牛肉は39%減少した点である.一方で,国産牛肉の消費量は増加しなかった.そこで,BSE以後の牛肉の国内需要の実態を明らかにするため,牛肉を対象とした需要体系分析を行った.その結果,国産牛肉は特に品質が隣接する畜種間でこうした「つぶし合い」の効果が大きく,一方,輸入牛肉はほとんど影響を受けていないことが明らかになった.

    China plays a major role in global cotton markets and lower cotton imports by China could reduce global cotton prices significantly. In this study, we provide a methodology for total factor productivity (TFP) of China’s agriculture under data availability limitation. As a case study, we apply this TFP methodology to cotton production.

    Since 2001, Shiga prefecture has promoted environmentally friendly agricultural products through the “Kankyo Kodawari” certification. This certification can be divided conceptually into two parts: reducing the use of chemical fertilizers and pesticides, and preventing water degradation due to soil erosion from paddy fields. The former has both private and public benefits, while the latter has public benefits. We investigate the evaluation of environmentally friendly rice by residents through a choice experiment. We collected data through a mail survey with random sampling from the voters’ list. The results show that environmentally friendly rice is valued about 1,000 yen/5 kg higher than conventional rice; however, that value does not stem from preventing soil erosion alone. Rather, this premium is attributable to reducing the use of fertilizers and pesticides.

    Many agricultural brands in Japan do not have product management systems, such as product standards and monitoring systems for maintaining standards. This study aims to understand consumer evaluation for constructing a product management system in Kagoshimakensan Kurobuta, one of the most popular brands of pork in Japan, using choice-based conjoint analysis. Moreover, we examine the determinants of marginal willingness to pay for a product management system. The results are as follows. First, we show that a product management system raises the willingness to pay for Kagoshimakensan Kurobuta. Second, safety concerns of food and buying in mail order business have positive effects on marginal willingness to pay for a product management system.

    This study examines the technical details and trends of plant breeding technologies by analyzing patent applications. The study uses text mining for patent application date of Monsanto and Syngenta from 2000 to 2017 for the following results. First, there has been rapid improvement in genome editing technologies, which enable the generation of new traits from endogenous genes. Especially, the two companies focus on R&D in genome control and regulation, which are necessary techniques in using genome editing technologies. Second, there has been a rapid increase in plant varieties with environmental tolerances to drought, cold, and nitrogen to counter the effects of climate change.

    In this study, we evaluate the economic potential of biomass power generation using rural sewage sludge in Hokkaido prefecture, Japan, using a cost-benefit analysis. We show that the return on investment for facilities of biomass power generation using rural sewage sludge was lower than the total investment cost.

    In Japan, the scale of rice farming management has been expanding (business size and farm size). We monitored diversification strategies and business innovation in rice farming. We selected three large-scale rice farms as the subjects for our case study. The study aimed to (1) examine diversification strategies for business and product sales, and (2) discuss the characteristics of diversification strategy and options for handling issues that may arise in future. Focusing on management objectives and sales management, we investigate the characteristics of diversification strategy in corporate rice farming. The survey results revealed that farmland location is important for an effective diversification strategy, as it influences both vertical and horizontal diversification in corporate rice farming.

    本論文では京都・奈良の山村部に移り住んだIターン者を事例に,その農村活性化に果たしうる役割を検討する.ここではIターン者の貢献を(1)村落の既存の機能や活動の再活性化,(2)これまでにない新しい活動の導入,という二つの側面から分析した.まず公的な村の組織活動については,Iターン者は寄合や村の共同作業に可能な限り参加しようとする姿勢がうかがえた.Iターン者はまた,村の伝統芸能や祭りの保存に深い関心をもち,積極的に関わっている場合も多い.食料の一部自給を目指すIターン者も多く,有機農法や自然農法を実践している人が多かった.このようにIターン者は,既存の村機能を活性化させる意味でも,新しい試みをしていくという意味でも,さまざまな役割を果たす可能性をもっている.ただそうした役割を果たすためには,公的な行事や農作業などに積極的にコミットし,地元住民の信頼を得ることが重要であることも判明した.

    近年,携帯電話を利用した銀行取引,いわゆるモバイルバンキング(Mバンク)が,より多数の人々の銀行サービス利用を企図して低所得途上国で導入されている.しかし,Mバンク利用に関する実証研究はバングラデシュなどの途上国では限定的である.本研究の目的は,バングラデシュ農村世帯がMバンクに加入する要因を明らかにすることである.計量モデルでは,Mバンク加入の有無(または時期)を被説明変数,Mバンクがバングラデシュに導入される直前の世帯主及び世帯の属性を説明変数として設定した.多項ロジット・モデルの推定から,教育水準,性別等の世帯主属性やMバンクが導入される前の携帯電話の保有がMバンク加入に有意な影響を与えていたことこが見出された.

    Tariffs, export subsidies, and income supports are major examples of agriculture protection by developed countries. However, comparing the revealed trade advantage and nominal rate of assistance, there is no clear evidence that protection affects trade. Therefore, this study examines the impact of agricultural protection policies on agricultural competitiveness using a fixed effect model with panel data of 76 countries worldwide. The empirical results show that agricultural protection policies do influence agricultural competitiveness. In addition, as mentioned in several studies, the land-labor ratio and average wage partially regulate agricultural competitiveness. The empirical results suggest that agricultural protection policies do reduce trade volume and can cause economic inefficiency at the same time.

    This study examines the development process and problem solving in the restaurant business through regional cooperation, using a case study of restaurant chain company “W” in Kobe City and Tosashimizu City. Close examination of materials provided by W and some stakeholder interviews have revealed three points, as important factors of regional cooperation in the restaurant business. The first is business matching by the coordinator tying an urban and rural community and gradual commercialization. The second is a stable food supply chain and reduction in distribution costs due to regional cooperation. The third is the allotment of appropriate roles depending on the strengths of each actor. This case study shows the possibility of regional cooperation in the restaurant business as a win-win scenario for cooperating businesses.

    The study analyzed the actual condition of company B, which is using SNS to sell fresh agricultural products in China. The questionnaire survey shows that it may be possible to resolve some limiting factors in e-commerce in fresh agricultural products from the perspective of buyers, for example, searching for distributors, after sales service, establishing relationships of trust with sellers, asymmetric information, and so on. The study revealed that SNS is an effective way to develop e-commerce in fresh agricultural products.
