    1997年1998年にスリランカのエッパワラ地域で行った農家調査結果にもとづき、稲作農業に関するコストや所得を試算し、現代の稲作農家の経済状況に影響している要因について分析し考察した。その結果、第1に、肥料・農薬の投下量が米の収量に比例しており、このことはすでに稲作が近代化されていることを示しいてること。第2に、肥料・農薬の投下量は、経営面積に比例して増加し、稲作の収量は経営面積が大きくなるほど増加する傾向が見られる。しかし、それは肥料・農薬の投下量の増加ほど明確ではないこと。第3に、1エーカー当たりの稲作の粗収益と総コストは経営面積が大きくなるにしたがって増加するが、所得については、経営規模間の相違は見られないこと、などである。このように稲作の経営規模間の生産性にかかわる諸指標の間にズレがあることが明らかとなったが、その要因は、農業雇用労賃、農業資材費用と不十分な潅漑条件などにあると考えられる。スリランカの稲作は技術的には、一部潅漑条件や機械化などの不十分さはあるものの「緑の革命」や開放経済過程の条件下で近代化されたといえる。しかし、近年の低価格な輸入米の増加による生産者米価の低下や雇用賃金などのコストの高騰が、大規模経営のスケールメリットを不十分なものとし、経営的優位性が確認できない要因となっているといえる。そのため大規模経営農家は、稲作経営の一層の拡大ではなくて、金貸しや稲作以外の農業やサイドビジネスに投資する傾向が強まっでいる。

    "c+v" theory has been widely recognized as a fundamental theory which shows the relation between non-capitalistic family farms and the capitalistic economy, "c" and "v" express the constant capital and the price of agricultural labor or the required household expenses of a farm family, respectively. According to this theory, since "v" is prescribed by non-agricultural-employed laborer's wages, the rise in agricultural productivity brings profits and a land rent in addition to wages to some owner-farmers. Consequently, the farmer class decomposes capitalistics and employed laborers and capitalistic agriculture is born from owner-farming. With such an interpretation, "c+v" theory is regarded as the basic theory which shows the future vision of the capitalistic economy which includes owner-farmers. However, the vision of the formation of capitalistic agriculture with sufficient profits and a land rent has not been actualized in Japan. First of all, except for period immediately after the end of World War II, agricultural labor income has not been balanced by laborer's wages. It is shown clearly in this paper that the the theory has the following fatal problems. It depends on a semblance, "price of labor", and on an error in which value and price of small farmer's commodities are prescribed by laborer's wage law. The mechanism of formation of laborer's wages differs fundamentally from the value and price of small farmer's commodities. Therefore, "c+v" theory cannot be adjusted in the value theory and cannot have validity as a social economic theory. But, why, then, was such theory made into the basic theory on the agricultural problems? The reason is that it is exactly a reflection of the conflict included in the actual mechanism by which the farm family is reproduced, and that the conflict expressed by the mechanism of the reproduction of a farm family is the constant antagonism between the family farm and the capitalistic economy. This paper clearly shows from the structure of this reproduction that the subject entrusted to this theory is in the grasp of the conflict between capitalism and agriculture. Present family farming theory should be built by the result of capital accumulation movement rather than capital theory. However, the conventional theory which makes the cost price theory a starting point therefore is based on what the capital law realizes. Consequently, it has a fatal defect in dealing with problem exceeding capitalistic economy, such as agricultural environmental problems and national agreements regarding of supporting agriculture. That is the reason that we ask for the abandonment of "c+v" theory as the first step toward resuscitation of the theory on agricultural problems.

    フィリピンにおける米の自給水準は1970年から1999年までのこの30年間、漸減している(年率0.16%)。一方人口と消費は同時期にそれぞれ年率2.32%、2.73%と高い割合の増加を示している。米生産の停滞要因として、灌漑の未整備、異常気象、高品質品種の未使用、収穫後の施設不足などを指摘することができる。そのため米の自給目標を達成しようとするフィリピンにおける取り組みの現状と将来は、決して明るいものではない。もし、政府によって適切な対策がとられなければ、米の国内生産量の不足により、安定した米供給が不可能となり、輸入量を増加させなければならなくなると考える。しかも、世界の米市場は小さく、また変動しやすい状況にある。それ故、国内自給を高めなければ、それに代わりうる安定した確実な方策は見いだすことができない。それ故、フィリピンにおいては今日、米の自給を政策的に実現することが、政治的、社会的、経済的に大きな意義があることを明確に主張し続けなければならなくなっている。そのために政府は、灌漑施設や乾燥・貯蔵施設の整備に投資をすることをはじめ、農民のそれらの利用率の向上や技術の収得が必要になっている。

    Currently, the U.S. agro-food sector is in the midst of transformation process so-called 'Industrialization.' Under this structural change, it is increasingly critical for farmers and their cooperatives to get involved forward into value-adding stages in the commodity chains. Rapid development of the new generation cooperatives (NGCs) in the 1990's can be recognized as one of the possible alternatives to cope with this challenge. The NGCs are apparently different from conventional farmers' marketing and/or supply cooperatives, with the most characteristic and critical system of 'delivery right share.' A unit of delivery right share represents (1) the legal right and duty to deliver a defined amount of agricultural product to the cooperative, (2) the right to receive cash dividends in proportion simultaneously both to the patronage and to the equity investment. And (3) it is transferable, with appreciated or depreciated price reflecting the value of the cooperative as a business entity. With this system, the NGCs can successfully address the free-rider problem, horizon problem, and portfolio problem. These problems are among the critical reasons why the members of conventional cooperatives hesitate to increase their equity investment, and consequently the cooperatives suffer from the lack of sufficient capital necessary to enter value-adding activities. Among the main conclusions from the case study on some NGCs' in the grain producing area are as follows. The value-adding activities on agricultural raw products by NGCs, particularly in the special commodities and/or niche markets, are effective as means to retain more value in the hands of farmers, as well as to revitalize the rural economies. On the other hand, the NGCs, activities in the more generic commodities and/or oligopolistic markets, where they must compete with the huge multinational agri-food businesses, are somewhat complicated. Because of the scale-economy, tough competition, and relatively generic character of the farm products, it is difficult to remain the delivery right share system, and then the NGCs are faced to the likeliness to transform into the large regional cooperative approach, or even to the invester-oriented firm approach.
