According to economist Schumacher, appropriate technology is a cheap and less restrictive technology that aims for small-scale production activities that can be done by the local people using local materials, small capital and relatively simple technology. For this reason, aid from the poorest countries and the developing world through proper technology has been receiving much attention recently. In the meantime, the central approach to providing large-scale infrastructure, which was promoted in the form of exclusion of substantial participation by local residents, was ultimately not sustainable within the local community. The survival of Official Development Assistance(ODA) through proper technology is to ensure that local residents have sustainable capacity even if aid from donor countries is suspended by actively collecting opinions from local residents about technologies needed by local residents. The World Intellectual Property Organization (WIPO) held a proper technical competition to find the right technologies with the Korean Intellectual Property Organization (KIPO) and developing countries' patent offices, and analyzed and evaluated the process, current situation, and representative cases. The WIPO project for finding the proper technologies was reviewed through 18 evaluation results, and while some improvement was needed in the sustainability of the competition, it was highly successful in terms of relevance, effectiveness, and influence. Based on the results of the WIPO project from the perspective of the OECD DAC evaluation standards, seven suggestions are proposed for sustainable development. They include the standardization of competition manuals for each country's patent offices (P-1), the segmentation of support fields (P-2), strengthening the government's engagement policy for promotion events (S-1, C-1), the operation of intellectual property education programs (C-1), the provision of business models tailored to winning prizes (C-2), the sharing of public relations and marketing strategies of each country, and regular international symposiums (G-2). It also suggests holding an international competition in the mid- to long-term cycle of three to five years. In this case, considering the seven proposals for sustainable development of WIPO technology exploration projects in terms of time and budget, the International Competition aims to first share a feasible proposal, such as P-1, P-2, and then to share C-1, G-1 and G-2, and finally to share S-1, G-1 and G-2. Because the WIPO project has a special nature that leads to active cooperation of the recipient country from the stage of demand development, it can be said that the ideas proposed in the region will grow and have strong power in the future when active related policy linkage and continuous support of the recipient country continue, which will have a positive impact on the economic ecology of the region. The WIPO project, which starts with the voluntary participation of the recipient country, is well worth it as a prime mover that gives hope to developing countries in the future.
