Abstract
This study selects a case involving water purification systems in Binh Dinh, Vietnam, as an appropriate example to examine appropriate technology (AT) acceptance factors and derive possible insights into the stable settlement and development processes whereby to diffuse AT. This analysis administered questionnaires to users of water purification systems installed in five elementary and middle schools in Binh Dinh, from which 296 samples were collected for the final analysis. The original unified theory of acceptance and use of technology (UTAUT) was modified by incorporating the factors of physical support and educational support, and empirically studied using structural equation modeling. The findings revealed that all constructs significantly affect the behavioral intentions toward AT, of which performance expectancy and physical support have the most significant impact. Thus, understanding local needs and improving the quality of life by spreading AT are key in its acceptance and diffusion. Furthermore, sustainable technology is guaranteed only if human and economic support is accompanied by AT development that fits the local context and environment. Finally, the analysis results, that moderating effects differ by role, imply that educational support’s influence varies between manager and student groups.
Highlights
Humanity has evolved to unprecedented levels as a result of its technological advancements
This study considers the importance of performance expectancy, and assumes this will positively affect the usage of water purification systems
This study examined the factors determining appropriate technology (AT) acceptance among the residents of Binh Dinh, Vietnam, with an aim to provide and spread sustainable AT
Summary
Humanity has evolved to unprecedented levels as a result of its technological advancements. Modern technology has significantly influenced all social aspects by improving human productivity and the quality of life. A wide technological gap simultaneously exists between developed and developing countries, which is difficult to bridge as innovative technologies are developed on a foundation of high-level technology. One possible solution to reducing this gap is appropriate technology (AT), proposed by British economist E.H. Schumacher [1]. AT has been widely discussed among engineers, researchers, and policymakers as a solution for the purported “others” deprived of modern technology and its benefits
