THE RURAL POOR AND TECHNOLOGICAL OPPORTUNITY IN THE DRY ZONES OF SOUTHERN ASIA
探讨农业经济学家在评估技术创新中的角色转变，从比较外源与本土技术，转向研究生态脆弱、低产地区中影响贫困家庭的多点创新及其制度条件。
In contributing to the appraisal and evalution of technological innovation, agricultural economists have a major but changing role to play. Whereas hitherto the concern has been chiefly to compare sharply different exogenous and indigenous technologies, the challenge now is to assess technological change of either or both these kinds in ecologically sensitive and relatively unproductive areas when the bulk of the people are poor and survival is the most common preoccupation where innovations could impinge at many points in household life‐systems but are, singly, likely to have only small impact where the institutional structure will be crucial to their acceptance and might itself have to change.
