W. RUTTAN AND YUJIRO HAYAMI I. Introduction The "technology factor," in either its embodied or disembodied form, is increasingly recognized as a major source of differences in productivity and welfare over time and among nations.' Yet techni- cal change is one of the more difficult products for a country in the early stages of economic development to produce. In agriculture the initial success of the "green revolution" has resulted in renewed interest in the economic and institutional considerations involved in international technology transfer.2 The international diffusion of agricultural technology is not new. The classical studies by Sauer and Vavilov and the more recent cytogenetic studies of plant origins indicate that the international and intercontinental diffusion of cultivated plants, domestic animals, DR.

It was presented at the Conference on Agriculture and Economic Development, Japan Economic Research Center, Tokyo, September 6-10, 1971. The paper draws exten- sively on the book by Yujiro Hayami and Vernon W. Ruttan, Agricultural Development: An International Perspective (Baltimore, 1971).

W. Ruttan and YujiroHayami hand tools, and husbandry practices was a major source of productivity growth in prehistory and in the classical civilizations.3 It is well known that the transfer of new crops (potatoes, maize, tobacco, and others) from the new continents to Europe after the discovery of the Americas had a dramatic impact on European agriculture. The technological bases for the staple exports of many developing countries-cocoa in West Africa and rubber in Southeast Asia, for example-occurred as a result of the international diffusion of crop varieties. Before agricultural research and extension were institutionalized, this diffusion took place as a by-product of travel, exploration, and communication undertaken primarily for other purposes.4 Over a long gestation period-several decades and even centuries-exotic plants, animals, equipment, and husbandry techniques were gradu- ally introduced and adapted to local conditions. In the 19th century the international diffusion process became more highly institutionalized. National governments established agencies deliber- ately to seek out and introduce exotic crop varieties and animal breeds.5 Colonial governments and the great trading companies operating under their protection sought to introduce crops with export potential into new areas of cultivation. Over time, these efforts have had a substantial impact on the location of staple production and on international trading patterns in crop and animal products. The enormous agricultural productivity differences among countries, combined with the success of earlier diffusion efforts, have 3See Carl O.

This perspective im- posed a "naive diffusion" or "extention bias" to much of the national and international aid efforts for agricultural development that emerged after World War II. In reviewing the agricultural development efforts of the 1950s and early 1960s, Albert Moseman em- phasized that "this 'extention bias' met with only limited success because of the paucity of applicable indigenous technology and the general unsuitability of U.S. temperate zone materials and practices to tropical agricultural conditions."6 JIn this paper, from earlier research on the diffusion of culture and technology, we draw insights that can contribute to a more adequate understanding of the processes involved in the international transfer of agricultural technology and the impact of such transfer on the location of agricultural production and international trade in agricultural commodities. This analysis leads us to place major emphasis on the emergence of national experiment-station capacity for adaptive research and development as a critical element in the international transfer or "naturalization" of agricultural technology. II. Diffusion Models and International TechnologyTransfer There are multiple traditions of research on diffusion processes: in anthropology, economics, geography, sociology, and other dis- ciplines. Each tradition has evolved a somewhat different model of the diffusion process. Aside from differences in terminology, real differences among these models exist because they are concerned with different aspects of diffusion phenomena. The main focus of sociologists and geographers has been on the impact of communication (or interaction) and sociocultural resistance to innovation on the pattern of diffusion over time and across space.7 The models of 6A.
